Excessive heavy metal content in soil can seriously hinder plant physiological metabolism and growth. This study, with soybean, examined how drip irrigation reduced toxicity. The experiments four frequencies were conducted by controlling the lower limit of matric potential (D1: −10 kPa; D2: −20 D3: −30 D4: −40 kPa). Through comparison traditional surface irrigation, effects on distribution, soybean growth status, transcriptome under Cd, Pb Cr(VI) composite pollution comprehensively analyzed. results show that (i) Cr(IV) migrated away from thereby reducing inhibition stress at root, among which D1 had best improvement effect (ii) Drip improved resistance to stress, promoted transport fixation free Cd2+, Pb2+ Cr6+ cells, damage oxidative ions cell structure. (iii) was conducive energy supply protein stability metabolism, helped activity. Overall, compared toxicity metals soybeans moving out root zone enhancing this study provide a theoretical basis for application technology prevention control pollution, new strategy safe production agriculture.

ABSTRACT Lead (Pb) and arsenic (As) pollution seriously affect the physiological biochemical processes of plants, reduce agricultural productivity, pose a serious threat to human health. Recently, there has been an increasing interest in studies aimed at mitigating these negative effects heavy metals. Curcumin is important secondary metabolite belonging polyphenol class that provides stress tolerance plants through its metal‐chelating activity. Therefore, our study, curcumin (Cur1; 50 μM Cur2; 100 μM) was applied lettuce ( Lactuca sativa L.) under lead (Pb; and/or (As; stress. It observed relative growth rate plant decreased by 12% Pb 27% As combined conditions (Pb + As) reduced water content 23%. Notably, significant increases parameters were following treatment. Furthermore, exogenous application effectively mitigated detrimental induced heavy‐metal On gas exchange photosynthetic parameters, Cur1 treatment resulted more than twofold increase carbon assimilation conditions. Due exposure, H 2 O increased 25% TBARS twofold. These elevations attenuated with enhanced antioxidant enzyme Compared Cur2 treatments 40% 24% SOD activity, respectively. contributed maintenance redox balance cell activity ascorbate–glutathione (AsA‐GSH) cycle. In conclusion, applications reduction ROS accumulation uptake, photosynthesis efficiency, capacity. findings suggest phenolic compounds like could be promising strategy practices enhance resistance stress, thereby improving productivity.

Chickpea (Cicer arietinum L.) productivity is hindered by biotic and abiotic stresses, particularly heavy metal toxicity. The pot experiment was carried out at the botanical garden of Islamia University Bahawalpur, Bahawalpur-Pakistan. experimental treatments comprised following details: T0 = Control + 0 µM MT, T1 15 T2= 30 T3 100 Cd T4 MT T5 MT. A completely randomized design (CRD) with three replicates used. stress significantly reduced shoot fresh (51.3%) dry weight (50.4%), total chlorophyll (53.6%), Ca2+ (56.6%). However, it increased proline (38.3%), phenolics (74.2%), glycine betaine (46.4%), TSS (67.7%), TSP (50%), SOD (49.5%), POD (107%), CAT (74.2%). Conversely, improved (78.5%) (76%), (47%), (26.5%), (35.8%), (27.8%), (19%), (24.5%), (25.8%), Results indicated that enhanced photosynthetic pigments antioxidant activities, maintained ion homeostasis, reduces reactive oxygen species. Desi variety performed better than Kabuli, application effectively mitigated

Drought stress severely damages wheat growth and photosynthesis, plants at the grain-filling stage are most sensitive to drought throughout entire period of development. Exogenous spraying sodium nitroprusside (SNP) can alleviate damage caused by stress, but mechanism regulating proline pathway remains unknown. Two cultivars, drought-sensitive Zhoumai 18 drought-tolerant Zhengmai 1860, were used as materials when cultivated stage. The results show that under SNP pretreatment effectively improved physiological basis photosynthesis water use efficiency two increased their tolerance photosystem II (PSII) damage, maintained a normal photosynthetic rate yield. induced an increase in pyrroline-5-carboxylate synthase (TaP5CS) gene transcription, comparatively greater was detected 1860. When treatment applied before exposure, TaP5CS transcription further enhanced. Induction promoted accumulation response osmotic ability, net rate, thereby increasing dry matter yield traits. In this study, exogenous regulates genes related metabolism provides theoretical for establishment cultivation technology using resist stress.

Solanaceous vegetable crops are cultivated and consumed worldwide. However, they often confront diverse abiotic stresses that significantly impair their growth, yield, overall quality. This review delves into melatonin abscisic acid (ABA) biosynthesis roles in stress responses. It closely examines the intricate interplay between ABA managing within plants, revealing both collaborative antagonistic effects elucidating underlying molecular mechanisms. Melatonin mutually influence each other’s synthesis, metabolism of other plant hormones, a key focus this study. The study highlights melatonin’s role aiding management through ABA-dependent pathways genes melatonin-ABA interaction. Specifically, downregulates synthesis upregulates catabolism genes, leading to reduced levels. also directly scavenges H 2 O , enhancing antioxidant enzyme activities, thereby underscoring mediating Moreover, plays an essential multiple physiological processes including stomatal behaviors, wax accumulation, delay leaf senescence, seed germination, seedlings among others. Recognizing these relationships Solanaceae holds great importance for improving agricultural practices crop In summary, offers comprehensive overview recent studies on interplay, serving as valuable resource researchers breeders dedicated fortifying resilience productivity challenging environments.
