Changes were estimated in the morphology, physiology, photosynthesis, nodulation, and yield in two mungbean varieties ‘PKV AKM 12-28’ and ‘VBN (Gg)3’ under salt stress (0, 75, 100, and 125 mM NaCl) for 15, 30, and 45 days. Multivariate modelling was used to analyse results to explore complex data and to visualize time and concentration-dependent modulations. Principal component analysis showed modulations in morpho-physiological attributes such as shoot length, root length, the number of secondary branches, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight and leaf area; photosynthetic attributes such as chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll, total carotene and total anthocyanine content; nodulation attributes such as nodules per plant, size of the nodule, and fresh weight per nodule, and yield attributes such as number of pods per plant, fresh weight per pod, and seed characteristics such as the number of seeds per pod and fresh weight per 1000 seeds are key traits affected by salt stress and can be used as indicators. Discriminant analysis identified modulations in morpho-physiological attributes such as root length, leaf area, root fresh weight, shoot fresh weight, shoot dry weight, shoot length and photosynthetic attributes such as chlorophyll-a content, and mean nodule weight as discriminating variables at different salt concentrations. Besides, it identified modulations in morpho-physiological attributes such as root length, root fresh weight, photosynthetic attributes such as total anthocyanin content and total chlorophyll content, nodulation attribute such nodule size and nodule weight, and yield attributes such as pod number and number of seeds per pod are discriminating variables at various durations of salt stress. Principal component analysis and discriminant analysis identified ‘PKV-AKM 12-28’ as salt-tolerant and ‘VBN (Gg)3’ as salt-susceptible varieties. Multiple correlation analysis identified significant correlations among morphological, physiological, photosynthetic, nodulation and yield parameters.
研究了2个绿豆品种PKV AKM 12-28和VBN (Gg)3在0、75、100和125 mM NaCl盐胁迫下15、30和45 d的形态、生理、光合、结瘤和产量变化。多变量模型用于分析结果，以探索复杂的数据，并可视化时间和浓度相关的调制。主成分分析表明，茎长、根长、次生枝数、茎鲜重、根鲜重、茎干重、根干重和叶面积等形态生理属性均发生了变化;光合特性，如叶绿素a、叶绿素b、总叶绿素、总胡萝卜素和总花青素含量;单株结瘤数、根瘤大小、每节鲜重等结瘤属性，单株荚果数、每荚鲜重等产量属性，每荚种子数、每千粒鲜重等种子特性是受盐胁迫影响的关键性状，可作为指标。判别分析发现，在不同盐浓度下，根长、叶面积、根鲜重、茎鲜重、茎干重、茎长等形态生理属性和叶绿素-a含量、平均根瘤重等光合属性是区分变量。根系长、根鲜重等形态生理属性、总花青素含量和总叶绿素含量等光合属性、根瘤大小和根瘤重等结瘤属性、荚果数和每荚果数等产量属性的调节是盐胁迫不同持续时间下的鉴别变量。主成分分析和判别分析表明，PKV-AKM 12-28为耐盐品种，VBN (Gg)3为耐盐品种。多相关分析表明，形态、生理、光合、结瘤和产量参数之间存在显著的相关性。

Moringa oleifera Lam. leaves are commonly used for diabetes worldwide. To date, there has been no research study done to investigate its effect on lipid and carbohydrate profile in Algerian diabetic patients. This pilot clinical study aimed to evaluate its long term-effect on lipid and carbohydrate profile in Algerian diabetic patients in preparation for a larger trial. 44 diabetic patients from Adrar city were administrated with 3600 mg of MO leaves powder twice a day at breakfast and at 7 p.m. for a period of 90 consecutive days, along with their regular hypoglycemic medications, in order to evaluate their serum lipid (TC, C-HDL, C-LDL and TG) and carbohydrate profile (blood sugar and HBA1c), weight, BMI and blood pressure, across five time-points (on days 0, 3, 7, 30, and 90). The results showed that oral administration of Moringa oleifera powder had a statistically significant effect on blood sugar (HBA1c), LDL-C, HDL-C levels in diabetic patients (p<0.05). Moringa oleifera leaf powder seemed reduced LDL-C, and HBA1c and elevated HDL-C, in diabetic patients. No side effect was reported by any participant. However, it did not have a statistically significant effect on weight, BMI and blood pressure. The data from the present clinical trial provide persuasive, although preliminary evidence supporting the therapeutic potential of Moringa oleifera leaf powder for managing chronic hyperglycemia and dyslipidemia in Algerian patients with diabetes. A more extensive trial is necessary to determine the Moringa oleifera leaf powder optimal dose and evaluate if its effect results into long-term advantages. In addition, further investigations are required to clear the underlying mechanisms involved with these effects.

The objectives of this study were to test the strain Wickerhamomyces anomalus WO2 as a plant growth-promoting yeast (PGPY), to evaluate the effect of its inoculation on the growth and physiological performance of Suaeda fruticosa subjected to salt stress, and to understand by which mechanism the yeast can protect the plant from high salinity. The results showed that the strain is halophilic, and grows at salt concentrations of up to 15%. Salinity caused decreases in chlorophyll a, b, and T in both inoculated and non-inoculated S. fruticosa. A significant increase in carotenoids was observed in W. anomalus WO2 inoculated plants. Inoculation enhanced the production of proteins, polyphenols and flavonoids at 1% of salinity, and sugars at all concentrations of NaCl. Although Na+ and K+ were higher in the leaves of non-inoculated plants compared to inoculated ones, the correlation of sodium translocation factor (TF) with salinity was very strong positive only in the inoculated plants. The production of carotenoids had a very strong positive relationship with salinity in inoculated plants, and a very strong negative correlation in non-inoculated plants. Soluble sugars were very strongly positively correlated with salinity in both inoculated and non-inoculated plants. However, a strong positive correlation of sugars with carotenoids was observed only in inoculated plants. This strain proved to be a promising candidate as a PGPY under salt stress. This work amends the PGPY bank with new strains having interesting abilities to resist high concentrations of NaCl and which can be used in the future as a biofertilizer.

The study was performed to investigate the possible neuroprotective role of palmatine, a protoberberine alkaloid against aluminum-induced aberration in neurotransmitter levels, excitotoxicity, neuronal inflammation, damage, and degeneration. 100 mg/kg of aluminum chloride served as the inducing agent and was administered orally to male Wistar albino rats for 42 consecutive days. Animals were divided into four groups, groups I, II, III, and IV which involve the normal group, the toxic control group receiving aluminum chloride, and two treatment groups administered orally with palmatine at a dose of 10 mg/kg and 20 mg/kg respectively followed by aluminum chloride. Expression of neuronal inflammatory markers like IL-6 and TNF- α were checked by the ELISA method. Deranged neurotransmitter levels of acetylcholine esterase and glutamate in rat brains were measured to determine the extent of excitotoxicity. The neuroprotective role of palmatine was determined based on histopathological studies and by determining BDNF expression by the immunohistochemistry method in rat brains. Palmatine treatment effectively regulated acetylcholinesterase levels and glutamate levels otherwise elevated by aluminum. It lowered excitotoxic damage induced by aluminum and lowered the degree of expression of inflammatory markers IL-6 and TNF- α. Improved expression of BDNF in palmatine-treated groups is indicative of the neuroprotective potential of palmatine in the restoration of neuroplasticity. Histopathology further confirms the neuroprotective potential of palmatine as the treatment significantly prevented neuronal damage degeneration and loss and restored healthy and viable neurons. The findings of the study confirm the neuroprotective potential of palmatine against aluminum-induced neuroinflammation and excitotoxicity.

Heavy metals including nickel have adverse effects on hematological system and red blood cells antioxidant defense. The purpose of the study is to examine the possible corrective effect of fig (Ficus carica L.) extract (FCE) on hematological parameters and antioxidant enzyme activities in red blood cells of rats exposed to sub-lethal concentration of nickel. Male Wistar rats were exposed to nickel chloride (10 mg/kg) and then treated or no with FCE (350 mg/kg) for 4-weeks. The intoxication induces alteration of haematological parameters and enhances blood haemolysis, generates oxidative stress induced decrease in the antioxidant enzyme activities and depletion in reduced glutathione levels in intoxicated group compared to the control group. The oral administration of FCE increase significantly hemoglobin levels (Hb), red blood cells count (RBC), hematocrit (Ht) and decreases white blood cells counts (WBC), and platelets in F. carica treated groups, and also the extract increase the GSH-Px and SOD antioxidant activity, GSH reserves in red blood cells, and reduces lipids peroxidation. The present study concludes that fig fruits may exhibit potent antioxidant potential for erythrocytes and have a positive effect on hematological system.

This study was conducted to investigate the effect of treatment conditions of plant growth regulators on the marketability of ‘Red Dream’, a triploid grape. In order to achieve the purpose of this study, gibberellic acid 3 (GA3) 100 ppm single use treatment group was set as a control group. In addition, the fruit characteristics expressed when cytokinins such as thidiazuron (TDZ) or forchlorfenuron (CPPU) 2.5 ppm or 5.0 ppm mixed with GA3 100 ppm were compared with the control group. Cluster weight was commonly higher in the mixed treatment of TDZ or CPPU than in the GA3 single use treatment, and it was found that the cytokinin mixed treatment could effectively induce the enlargement of ‘Red Dream’ berries. Although the harvesting period was slightly delayed compared to GA3 single use treatment in the case of mixed treatment of GA3 and TDZ or CPPU, there was no inhibition of coloration, soluble solid sugar content and functionality, which are important indicators of marketability. In particular, in the GA3 100 ppm + TDZ 5 ppm treatment group, where the enlargement of fruits was the largest, the occurrence rate of non-commercial berry was also found to be the lowest. Therefore, it is expected to contribute to strengthening the marketability of ‘Red Dream’ if such plant growth regulator treatment condition is applied during cultivation.

Basella alba is an underutilized vegetable with ethnobotanical importance used for culinary as well as medicinal purposes in many parts of the world. Morphological characterization and chromosome studies of the mitotic and meiotic cells of the green stemmed and the red-stemmed B. alba was carried out with a view to filling the knowledge gaps that exist in their morphological characterization and also to provide insightful information on their chromosome numbers and meiotic behaviour. The B. alba accessions studied were characterized with respect to their habit, leaves, inflorescence, fruits and seeds. Mitotic and meiotic studies were carried out on the Basella accessions using standard techniques. The morphological studies revealed significant differences between the green-stemmed and red-stemmed Basella alba with respect to the green/red colour of their stems, colour of the flower bud apex, mean plant height at flower bud initiation, mean leaf length, mean leaf width, mean petiole length, mean flower per spike, mean fruit length and mean fruit diameter. The cytological study revealed a chromosome number of 2n=4x=44 for both the green-stemmed and the red-stemmed B. alba studied. It also revealed the occurrence of chromosomal aberrations such as stickiness and precocious migration of chromosomes to the poles during meiosis, which could lead to irregular chromosome segregation that could result in chromosome instability and aberrant meiotic products within the species.

Nerium oleander var. ‘Villa Romaine’, commonly called oleander, is an ornamental shrub that exists in Tunisia in the wild and cultivated form. This plant is frequently propagated and produced in nurseries and used in urban plantings and on roadsides. The effects of nature of the plants (spontaneous or cultivated), climatic conditions (localities), and altitude (from 6 to 447 m) on seed shape, size, and germination of Tunisian populations, were investigated. Seeds were harvested from 23 locations belonging to six bioclimatic stages and distributed from North to South of Tunisia. The seed parameters studied were area, roundness, J index, and germination rate. A significant variation was obtained between populations, categories (cultivated and spontaneous), bioclimatic zones and altitudes. Seeds of cultivated plants were the smaller and showed the higher germination rates, compared with spontaneous populations, which had large seeds and a low germination rate. Climatic conditions and geographical location had an effect on seed morphology; seeds in lower humid were small for both cultivated and spontaneous types, they also showed a low J index value and a high germination rate. On the other hand, in upper Saharan, seeds were large and roundness and germination rate were the lowest. Also, seeds from plants in higher altitudes were the smaller and presented the lower values of the J index compared with those collected from low-altitude sites.

Also, seeds from plants in higher altitudes were the smaller and presented the lower values of the J index compared with those collected from low-altitude sites.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48842362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use and consumption of wood has always captured the attention of forest researchers, mainly from the point of view of forest management and the sustainable processing of raw materials. For this reason, the wood industry has not only been concerned with the maintenance of forests, but also with efficient processing. The objective was to identify, analyse and discuss the main elements that influence the efficient use of natural timber resources at a global, regional and local level, providing a historical and current perspective of the industrial forestry sector in Mexico. Historically, the wood industries worldwide have been concerned with applying intensive silvicultural treatments in native and artificial forest stands, in search of satisfying the demand of a growing market. In this context, industries evolved as processes needed to be more efficient. Therefore, efforts were made to reduce and take advantage of forest residues, at the same time various historical events generated additional needs. At present, the integration of silviculture and forest transformation allow to increase and improve the quality of the products generated. Through the application of intensive silvicultural treatments, products of a single species are obtained. However, it is possible to direct production to a specific market as the forest mass develops. For its part, selective treatments in uneven-aged forests maintain a constant production of diverse products for different specialized markets. In Mexico, it is imperative to analyse and generate innovative or competitive products derived from wood to improve the efficiency of forest harvesting.

Microsatellite markers previously developed for other leguminous species were tested for cross-genus transferability and evaluated for their potential usefulness in providing an improved assessment of the genetic relationships between two closely related taxa belonging to Onobrychis genus (Fabaceae). Candidate microsatellite markers were tested for polymorphism and replicability in sixteen populations of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. and O. montana. Out of the 23 SSRs, there were identified seven polymorphic loci. In total 32 alleles were detected and the number of alleles per locus varied from two to six. PIC values ranged from 0.375 to 0.6454, and four SSRs displayed a PIC > 0.5. Relative uniform rates of genetic diversity were obtained. In case of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. the observed and expected heterozygosity ranged from 0.100 to 0.952 and from 0.219 to 0.525, respectively, while for O. montana ranged from 0.166 to 0.750 and from 0.083 to 0.375, respectively. Seven polymorphic SSRs with clear and reproducible amplification were identified. These markers proved to be very efficient for unambiguous population discrimination based on both geographic and taxonomic criteria. Hereafter, these SSR markers can be used as tools for evolutionary studies in Onobrychis genus, as well in providing knowledge on patterns of the species phylogeography.
