Drought is one of the major abiotic stress factors limiting soybean growth and yield, it frequently occur globally. Therefore, exploring resistant varieties from germplasm important under climate change. To screen drought spring at seedling stage, pot experiment was used to detect Survival percentage after 60 twice rehydration treatments on seedlings, evaluate tolerance soybean. The results showed that seven were considered tolerant, 17 sensitive, 36 be moderately tolerant. Based this experiment, number 44 (heinong37), 48 (heinong44), 49 (heinong45), 52 (heinong48) best resistant, 3 (dongnong48), 4 (dongnong52), 27 (suinong25), (heinong65) most sensitive. These provide a reference for further study resistance gene screening molecular level. selected can planted in areas with suitable climates frequent meet local demand. In other regions, although cannot directly grown, they still as parents or materials extraction, assist crop breeding level response increasingly severe problems current trends.

Sucrose phosphate synthase (SPS) is an important enzyme in the sucrose synthesis of plants, governing accumulation and distribution photosynthetic assimilates, which essential for plant growth stress tolerance. This study successfully identified eight NtSPS genes within genome cultivated tobacco. Phylogenetic analysis revealed that these are categorized into three subfamilies, a classification supported by examination their gene structures conserved domains. The promoters NtSPSs contained variety cis-elements associated with development, responses to phytohormones, resistance. Expression profiling demonstrated exhibit distinct expression patterns across different tissues under various conditions. Notably, majority genes, especially NtSPS5 NtSPS6, showed high leaves increased both roots following drought treatment. Furthermore, overexpression NtSPS6 tobacco plants significantly improved germination rate mannitol treatment enhanced activity antioxidant enzymes along chlorophyll fluorescence parameters stress. These results suggest have positive impact on tolerance plants. Therefore, this provides significant target resistance breeding lays foundation further investigation function regulatory mechanisms SPS genes.

Global climate change minimizes fresh water resources used in agriculture worldwide. It causes drought stress, which has adverse effects on plants. To ensure food security, crops and vegetables capable of tolerating shortages over the growth period are needed. This study aimed to elucidate morphological biochemical responses three colored cauliflower (Brassica oleracea var. botrytis) cultivars (Clapton, Trevi, Di Sicilia Violetto) one broccoli cultivar italica Magic) different irrigation treatments (85–100%, 65–80%, 45–60%, 25–40% field capacity). Assessment parameters revealed no significant difference among all for root weight, leaf area, floret size. Major reduced stem weight Clapton cultivar. Additionally, under severe only Violetto had a decrease plant height, but impact number leaves was observed. The measurement pigment contents showed carotenoids cultivars; just chlorophyll decreased with moderate stress research demonstrates that likely drought-tolerant common regimes may be reviewed.

The Dof gene family represents a class of plant-specific transcription factors that play crucial regulatory roles in various biological processes, including plant growth, development, and responses to abiotic stress. However, genome-wide identification functional characterization the remain unexplored Dendrobium officinale. In this study, we performed analysis DoDof family. A total 28 members were identified named DoDof1–28 based on genome annotation data. Phylogenetic classified these genes into four major groups (A–D) further subdivided them nine subfamilies. Gene structure revealed most DoDofs lack introns, with no distinct specificity observed among different subfamilies considerable diversity within same subfamily. Sequence alignment demonstrated all proteins contain conserved domain consisting 52 amino acids, which includes C2-C2 zinc finger motif DNA-binding domain. MEME composition exhibits certain degree conservation proteins, but significant differences exist across Expression pattern have exhibited diverse expression profiles developmental stages, tissues, under stresses (such as low temperature, salinity, drought) D. officinale, suggesting their potential development stress responses. Subcellular localization indicated DoDof15, DoDof22, DoDof24 are localized exclusively nucleus. Yeast one-hybrid assays DoDof22 binds promoter ABA receptor DoPYL9, while DoDof15 bind bHLH factor DobHLH68. These results suggest may regulate response processes officinale by binding promoters target genes. This study provides critical insights Orchidaceae establishes theoretical foundation for molecular breeding resistance improvement

Abstract This dynamic system simulation model was designed to describe Indonesia’s soybean availability system’s structure. Methodologically, this the first application combine production subsystem, demand and import subsystem in one model. study provides an overview of current future conditions system. Readers will know how next 20 years be state level, demand, imports, self-sufficiency ratio (SSR), dependency (IDR) commodities Indonesia. The forecast results were significant because it concerned with soybeans future. If situation is not known, then impossible anticipatory steps that need prepared early. driving factor lies productivity size crop area. number imports shortage, while depends on population growth. showed increase area have impact posture structure changes occurred a shift SSR value higher IDR lower. Finally, article presents various policy simulations based measurable rational targets stakeholders can use.

Drought deficit inhibits oat growth and yield. Fulvic acid (FA) can enhance plant stress tolerance, but its effects on regulating the ascorbate–glutathione cycle, chlorophyll synthesis, carbon–assimilation ability remain unclear. Therefore, this study aimed to elucidate physiological mechanisms of FA regulation drought tolerance in oats relationship with yield using drought-resistant variety Yanke 2 drought-sensitive Bayou 9. The yield, antioxidant system, capacity under were investigated by systematically assessing changes morphogenesis, intermediates, enzyme activities, carbohydrate metabolism. results showed that stress, treatment significantly promoted (leaf area, dry matter) elevated glutathione peroxidase, ascorbate reductase, dehydroascorbate reductase reduced ascorbic acid, content. In addition, increased chlorophyll, as well magnesium protoporphyrin IX, protochlorophyllin ester content, enhanced 1,5-bisphosphate ribulose carboxylase, carboxylase enzyme, 1,7-bisphosphate sestamibiose heptulose esterase, 1,6-bisphosphate fructose aldolase, sucrose synthase, phosphate invertase, neutral invertase sucrose, glucose, Overall, fulvic alleviates drought-induced damage enhancing promoting biosynthesis, improving carbon assimilation (Yanke 2) was more effective application compared (Bayou 9). This research provides valuable insight into potential a biostimulant abiotic stress.

Melatonin is an important, multifunctional protective agent against a variety of abiotic and biotic stressors in plants. Caffeic acid O-methyltransferase (COMT) catalyzes the last step melatonin synthesis plants reportedly participates regulation stress response tolerance. However, few studies have reported its function melatonin-mediated drought resistance. In this study, CrCOMT was identified strongly induced by Carex rigescens. overexpression transgenic tobacco increased tolerance to with high levels seed germination, relative water content, survival rates. improved membrane stability, exhibited lower electrolytic leakage malondialdehyde as well higher photochemical efficiency than wildtype (WT) under stress. The also had proline accumulation antioxidant enzyme activity, which decreased oxidative damage due reactive oxygen species (ROS) hyperaccumulation transcription ROS scavenging genes significantly WT addition, content conditions. Exogenous applied C. rigescens confirm mediating tolerance; were higher, melatonin-treated untreated summary, these results show that plays positive role plant regulating endogenous content.
