But the present scenario has forced mankind to search for alternative options. While keeping in mind the concept of sustainable agriculture, pest management including termites and other phyto-diseases etc. needs to be focused. For the achievement of the above stated goal, eco-friendly and cost-effective strategies need to be emphasized. Biopesticidal agents that mainly comprise of herbal and microbial formulations are known to exhibit anti termite activity and have a pivotal role in the production of organic food products. In order to reduce the chemical consumption, the vast area of biological alternatives needs to be explored as they provide us with many beneficial aspects like sustainability, suitable application, biodegradable nature, target specificity etc. Further, the bioactive components of such biological agents can later be used as commercially viable termititoxicant in the form of formulations. These herbal and microbial termititoxicants are effective and have immense scope to be used in future for sustainable development.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78883875","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 present study was undertaken to bring insights into the traditional use and distribution pattern of three Aconitum species from the region. An ethnobotany-directed approach was employed to study the conservation status of three Aconitum species. Their phytochemical profiles and biological properties were screened under in vitro conditions. Folin–ciocalteu and Aluminium chloride assays were employed to measure their total phenolic and total flavonoid contents, respectively. Plant extracts were evaluated for antioxidant, antimicrobial and anti-inflammatory activities. Three Aconitum species, viz. Aconitum heterophyllum Wall. ex Royle, Aconitum violaceum Jacquem. ex Stapf and Aconitum chasmanthum Stapf. ex Holmes showed dwindling conservation status in Kashmir Himalaya. Aconitum extracts showed significant variations in total phenolic and flavonoid contents. Antioxidant activity of Aconitum chasmanthum methanolic extract was studied to be comparatively higher (80.115%). Aconitum chasmanthum DCM & methanolic extracts showed a good MIC value of 0.125 mg/ml against Candida albicans and Streptococus pyogenes, respectively. The percent inhibition of NLRP inflammasome was found significant in Aconitum violaceum ethyl acetate extract (74.61%). The present study revealed that Aconitum species are constantly declining at least in investigated habitats of Kashmir Himalaya and hence need strategic conservation planning. The results also emphasized the utility of Aconitum species as an antioxidant, antimicrobial and anti-inflammatory agent that could be used to manage various health problems.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75123925","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}

They are 5 times denser than water (Tchounwou et al., 2012). Nowadays, it is a serious issue to keep safe environment from two important biologically hazardous heavy metals viz. Arsenic (As) and Cadmium (Cd). Since heavy metals are non-biodegradable and hence can be separated out through different physical or chemical process (Jung et al., 2017). Arsenic can be found in different forms depending upon its oxidation state or valency which ranges from +3 to +5. Arsenite with oxidation state +3 is more toxic than arsenate, which contains the oxidation state of +5 (Gupta, 2007). According to the World Health Organization (WHO, 2011), arsenic exhibit high toxicity in its inorganic form, that can be found in contaminated drinking water, food preparations from contaminated water, contaminated food crops etc. whereas cadmium is a byproduct mainly of mining origin, extracting and refining the zinc and least amount from lead and copper ores . Arsenic is a potent carcinogenic agent and can cause conjunctivitis, skin lesions and hard patches on the palms and feet; on the other hand, cadmium can damage the kidneys, lungs and livers by deposition and can exhibit chronic & acute effects respectively (Rashid & Mridha, 1998). Most importantly, cadmium deposition shows the longer half-lives in human body that sustains throughout lifetime (Andreae & Klumpp, 1979). According to WHO’s guideline value for arsenic and cadmium in drinking water should be lower than 10 μg/L and 3μg/L respectively.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82203132","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}

Nitrogen fixing cyanobacteria play a vital role in the maintanence of soil fertility and sustainability in rice field ecosystems (Roger & Reynaud, 1979). Cyanobacterial inoculation to rice crop was found to be effective in different agroclimatic conditions like tropical or temperate climates and soil types such as saline soils, phosphorous rich soils, alkaline or acidic soils etc. (Singh et al., 2017). The paddy field ecosystem provides an environment favourable for the growth of cyanobacteria with respect to their requirement for light, water, temperature, humidity and nutrient availability. In submerged soil system, biological nitrogen fixation contributes 25 to 30 kg nitrogen per hectre for one cropping season (Saexena et al., 2007; Kaushik, 2001). They are cosmopolitan in distribution and occur in every conceivable habitat where life is possible. They are reported to occur in extreme climatic conditions such as hot springs, polar deserts and Antartic regions (Halder, 2015, 2016). Even though they are ubiquitious, they prefer to grow in rice fields because the soil pH, temperature, humidity, crop canopy and soil moisture are favourable for its growth in paddy fields. It releases a large number of secondary metabolites into the paddy fields which also influences the growth of paddy (Wilson, 2006). The beneficial effect of cyanobacterial biofertilizer for paddy such as increase in number of tillers, seeds, length of the plant and leaf, yield etc. has been well documented (Karthikeyan et al., 2009; Sao & Samual, 2018; Radhakrishnan & Venkitaraman, 2005). Cyanobacterial biomass is also used for the production of various bioactive compounds, food items and biofuels (Hall et al., 1995; Malik et al., 2001; Paumann et al., 2005). They can control the deficiency of nitrogen in the soil and also improves its properties. Apart from nitrogen fixation, it also influences the overall growth of paddy including the grain yield (Roger et al., 1980; Singh, 1981; Alam et al., 2014). Since the urea and ammonium sulphate are the easily available and commonly used inorganic nitrogen fertilizer in the paddy fields of India, this made the the author to study how much these synthetic nitrogen fertilizers such as urea and ammonium sulphate influences the growth of paddy field cyanobacterium, Westiellopsis prolifica.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75500590","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}

Dass, Chhatar Sing Chouhan","doi":"10.25081/CB.2021.V12.6360","DOIUrl":"https://doi.org/10.25081/CB.2021.V12.6360","url":null,"abstract":"Coriandrum sativum L. (2n=22) is an annual herb that belongs to the family Apiaceae (Umbelliferae) is one of the most important cultivated (spice) crops in the world as well as India. Coriander is an aromatic plant, generally grown in winter. All the parts of the plant are edible but the fresh leaves and the dried seeds are most commonly used in cooking. It is an aromatic herb mainly used as a spice for adding taste and flavor to different food materials. The traditional uses of the coriander plants based on the primary products (fruits and the green herb) are medicinal and culinary (Bhati, 1988). The fruits are considered carminative, diuretic, tonic, stomachic, and antibilious. The essential oils of the fruits are possessing antibacterial and antioxidant activity (Bhandari & Gupta, 1991). Apiaceae is the 16th largest family of flowering plants containing about 200 genera and probably 2900 species; the family is cosmopolitan distributed worldwide except for Antarctica (Bentham, & Hooker, 1883). As per the Angiosperm Phylogeny Group system (APG) IV (2016) the family Apiaceae contains about 434 genera and probably 3,700 species. Polyploidy (having four completes sets of chromosomes) is relatively common in plants. By some estimates, as many as 70% of all angiosperms are natural polyploids (Masterson, 1994). A diploid plant can become polyploid due to disruption in mitosis or meiosis. It can and does occur in nature, but is also induced by using chemicals like colchicine. Colchicine is a chemical, has been used since 1937 in plant breeding work to produce changes in plants by doubling the number of chromosomes in cells, a condition referred to as polyploidy. The increased number of chromosomes usually brings about an increase in the size of the affected cells and various degrees of changes in their functions. A number of reports indicate that besides quantitative changes in plants resulting from polyploidy there also have been changes of qualitative character. These may be in color intensity of leaves and flowers; in fragrance of leaves, flowers, or other plant parts; and in content of oils, starches, sugars, and vitamins. Fundamentally these changes that are ordinarily considered qualitative are mostly, if not entirely, changes of quantitative nature, since they result from either an increase or a decrease of the various products naturally present in the plants. Many workers have worked out the effects of colchicine on different plant species such as; Cosmos sulphureus (Verma et al., 2011b), Chrysanthemum carinatum (Verma et al., 2017), Phlox drummondii (Verma et al., 2018) and Rhoeo discolor (Verma et al., 2011a).","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86935365","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}
