Cold stress has an adverse effect on eggplant growth and is a yield-limiting factor. Low temperatures are prevalent during early spring cultivation in temperate climates, and they have a negative impact on eggplant growth and development. Temperatures below the eggplant’s optimum growth temperature (22-30ºC) are considered low and detrimental to growth and development. In this review, we described how eggplants respond to moderately low and cold temperatures at different scales. We compiled literature on the current understanding of physiological, cellular responses to cold stress in eggplant as well as the transcriptional regulation during cold stress. Subsequently, we also highlight the genetic and molecular evidence, particularly the function of cold-responsive genes in strengthening cold tolerance in eggplant. Lastly, we covered the role of mineral nutrients and useful microorganisms in alleviating the consequences of cold stress in eggplant roots. Agronomic management practices such as the use of AMF species may mitigate the detrimental effects of low temperature and the enhancement of crop varieties with high yield throughout cold stress

Lettuce is one of the most consumed leafy vegetables in Turkey. The production of lettuce has been to get difficult due to infestation of cultivation areas with Bremia lactucae . This pathogen is genetically very variable. Pathogenic variation of B. lactucae has not been studied yet in Turkey. The objective of this study was to monitore the races of B. lactucae in the two geographic regions of Turkey. During the lettuce growing season in May and October 2018, totally 72 diseased leaf samples containing B. lactucae sporangia were collected from the fields of Bartın and Ankara provinces. From these samples 6 isolates were obtained. After a multiplication procedure, in which the susceptible lettuce cultivar 'Green Towers' was used, the B. lactucae sporangia were inoculated in differentiating lettuce cultivars. The response of the lettuce seedlings to pathogen was evaluated on the 7, 11 and 14 days after inoculation. The qualitative method was used for the assessment of infected seedlings. Sextet codes of Ankara and Bartın isolates were found as 44-00-01 and 13-03-04 respectively. The sextet codes of Turkish isolates did not match any of the present 37 races of B. lactucae . This result suggests that our isolates may be new races or pathotypes.

Fusarium oxysporum f. sp. lycopersici, Verticillium spp., and nematodes, as well as virus diseases that negatively affect production with limited chemical control cause significant losses in greenhouse tomato cultivation. The practical and effective side of controlling diseases is genetic control by breeding. Using a genomic approach for plant breeding is a more sustainable and effective way to control disease and pests. The development of the resistant line is improved by conventional breeding methods that can be conducted over a long period. However, molecular markers make these processes considerably shorter with identifying resistant individuals. In this study, 14 wild and 188 cultivated tomato genotypes have been tested against Fusarium oxysporum f. sp. radicis-lycopersici (FORL), Meloidogyne spp. (root-knot nematodes), Tomato spotted wilt virus (TSWV), Tomato mosaic virus (ToMV), Tomato yellow leaf curl virus (TYLCV) and Verticillum dahliae Kleb. (Ve) diseases and pests with using MAS (Marker-Assisted Selection) technique. According to these results, it has been determined that the selected markers can be used effectively in breeding studies to determine the diseases mentioned above.

This study was carried out to determine the resistance levels of some onion genotypes in Yalova onion gene pool by Fusarium testing during seedling stage. The isolate used in the study was Fusarium oxysporum f. sp. cepae , which causes damping off during the seedling stage and later basal rot in onion bulbs. The variance analysis for the onion seedling test and the mean differences against control were analyzed by using General Linear Model of the Tukey test. The germination rate of control seeds varied between 72% to 98%, while the germination rate of inoculated seeds varied between 39% to 93%. Texas Early Grano 502 showed the highest level of resistance with a survival rate of 83.8%, and resistance levels of 19Y07 and 19Y142 genotypes were higher than other genotypes. Resistance levels of 19Y51, 19Y15 and 19Y73 genotypes were lower than other genotypes. Akgün 12 showed moderate resistance with a survival rate of 59.6%. Determining the resistance levels of these onion genotypes during the seedling stage may be a preliminary step towards further studies

Understanding the attributes of spur leaves in apple trees is essential to gain more insight into the complex process of fruit development and quality. However, limited literature is available about the spur leaf characteristics of the 'Amasya' apple cultivar. In this work, the Soil Plant Analysis Development (SPAD) and leaf area were investigated in flowering and non-flowering spur leaves of 'Amasya' and six common apple cultivars. Significant differences among cultivars were observed for the SPAD and spur leaf area. The median SPAD readings in 'Amasya' were 32.63 and 26.23 for the flowering and non-flowering spurs, respectively, which were the relatively low values among studied cultivars. The maximum SPAD value was measured in flowering spurs of 'Cripps Pink' (45.03). SPAD values were found to be lower in non-flowering spurs compared with flowering ones for all the studied cultivars, which confirms that decline in chlorophyll content coincided with a gradual decline in productivity. A notably significantly lower spur leaf area was found in 'Amasya', whereas the highest spur leaf area was in 'Cripps Pink'. However, no statistical difference was observed between flowering and non-flowering spur leaf areas within the same cultivars. The present results provided a general framework of SPAD and spur leaf areas in 'Amasya' and other apple cultivars when spurs had flowers or not. Knowledge of these characteristics provides a basis for building a model related to yield elaboration of apple trees.

The purpose of this study was to analyze the development and fluctuation of basic food prices in traditional markets in Jakarta before and during the coronavirus disease (COVID-19) pandemic. The study used performance reports from the Indonesian Central Statistical Institute (BPS), National Center for Food Price Information (PHPI), various government agencies, the latest news from reliable online media, and similar studies. The scope of the research focused on the development of basic food prices in traditional markets from January 2019 to May 2021 in Jakarta, Indonesia. The basic food prices discussed in this study were shallots, rice, red chili, and garlic. Results showed that, the impact of the COVID-19 pandemic on the price fluctuations of shallots in the traditional markets of Jakarta was not significant. During the COVID-19 pandemic, rice prices remained stable due to the government's welfare program. The price of red chili in traditional markets tended to decrease due to the COVID-19 outbreak. The COVID-19 pandemic caused fluctuations in garlic prices in traditional markets in Jakarta, and this was because garlic imports from China faced logistical difficulties.

This study was carried out to test the effect of vacuum and open-air storage on seed germination, oil content, and sugar contents of four pepper cultivars. Seeds were stored at 13°C with 35% relative humidity over 48 months in vacuum packets or in perforated cheese cloth in a storage room. Seed samples were examined at 12, 24, 36 and 48 months. Seed germination, oil content and sugar contents were determined. Seed germination declined gradually as storage time extended. Vacuum storage had significantly higher (P<0.05) germination than oxygen storage after 48 months of storage for all cultivars. Differences between the two storage methods were not significant for the other samples, except Yaglik in which vacuum storage had higher values from 24 months onwards during storage. Total oil content declined in all cultivars but the decline was faster in seeds stored in the open air. A similar trend was also observed for sugar contents. Seeds stored in the presence of oxygen lost sugar content faster than vacuum-stored seeds. Results indicated that storage with vacuum conditions (no oxygen) extended the longevity of pepper seeds.

The quality of tomato fruit, from harvest to human consumption, requires a lengthy period for shipping, storing, and marketing. γ-aminobutyric acid (GABA) is a good candidate because it is a natural substance produced by plants to defend themselves against stress conditions. In this study, the effect of post-harvest GABA treatments at 0 (control), 5 mM and, 20 mM on the physical and biochemical properties and the polysaccharide content of tomatoes during 28 days of storage were investigated. Our results indicated that 5 mM of GABA treatment increased firmness and shelf-life by maintaining the integrity of fruits compared to control and 20 mM of GABA treated fruits. The fruits treated with 5 mM of GABA decreased the amount of WSP and the expression of cell wall related genes Pectate lyase (PL) and Polygalacturonase (PG). There was not a clear difference in colour index (CI) values among all treated groups at the end of post-harvest storage. Moreover, the tomato fruits treated with 5 mM GABA also showed somewhat less ethylene production, respiration rate and expression level of two ethylene synthesis genes ACS2 and ACS4 towards the end of storage. These results suggested that treatment with 5 mM GABA could be a beneficial strategy for maintaining the morphological and biochemical quality of tomato under postharvest storage conditions.
番茄果实的质量，从收获到人类消费，需要很长的运输、储存和销售时间。γ-氨基丁酸(GABA)是一个很好的候选物质，因为它是植物在逆境条件下产生的一种天然物质。本研究研究了采后0(对照)、5 mM和20 mM GABA处理对番茄贮藏28 d期间理化特性和多糖含量的影响。结果表明，与对照组和20 mM GABA处理的果实相比，5 mM GABA处理通过保持果实的完整性增加了果实的硬度和货架期。5 mM GABA处理降低了果实WSP含量，降低了细胞壁相关基因果胶裂解酶(PL)和聚半乳糖醛酸酶(PG)的表达。采后贮藏结束时，各处理组间的颜色指数(CI)值无明显差异。此外，5 mM GABA处理的番茄果实在贮藏后期乙烯产量、呼吸速率和两个乙烯合成基因ACS2和ACS4的表达水平均有所降低。上述结果表明，在采后贮藏条件下，5 mM GABA处理可能是维持番茄形态和生化品质的有利策略。
