Salinity is one of the most significant environmental factors limiting microalgal biomass productivity. In present study, model microalga Chlamydomonas reinhardtii (C. reinhardtii) was exposed to 200 mM NaCl for eight days explore physiological, biochemical and metabolomic changes. C. reinhradtii exhibited a decrease in growth rate, Chl b levels. induced ROS generation with increase H2O2 content. This caused lipid peroxidation MDA also an carbohydrate accumulation under conditions as storage molecules cells maintain survival. addition, stress increased content carotenoids, polyphenols osmoprotectant such proline.

Strategies of plants to overcome abiotic and biotic stresses

ABSTRACT In their environment, plants are exposed to a multitude of abiotic and biotic stresses that differ in intensity, duration severity. As sessile organisms, they cannot escape these stresses, but instead have developed strategies overcome them or compensate for the consequences stress exposure. Defence can take place at different levels mechanisms involved thought efficiency across levels. To minimise metabolic constraints reduce costs defence, prioritise first‐line defence apoplastic space, involving ascorbate, defensins small peptides, as well secondary metabolites, before cellular processes affected. addition, large number symplastic also provide efficient including chemical antioxidants, antioxidative enzymes, other peptides proteins. At both level compensation, specialised transporters be exchange membranes still not been identified, information on regeneration compounds remains ambiguous. exposure operate only cellular, organ whole‐plant levels, stomatal regulation, hypersensitive systemic responses prevent spread impacts within plant. ecosystem by root exudation signalling molecules emission volatile organic compounds, either directly indirectly into rhizosphere and/or aboveground atmosphere.

Опубликована: Янв. 7, 2025

Heat stress is one of the major concerns for wheat production worldwide. Morphological parameters such as germination, leaf area, shoot, and root growth are affected by heat stress, with physiological including photosynthesis, respiration, water relation. also leads to generation reactive oxygen species that disrupt membrane systems thylakoids, chloroplasts, plasma membrane. The deactivation photosystems, reduction in inactivation Rubisco affect photo-assimilates their allocation, consequently resulting reduced grain yield quality. development thermo-tolerant varieties most efficient fundamental approach coping global warming. This review provides a comprehensive overview various aspects related tolerance wheat, damages caused mechanisms tolerance, genes or QTLs regulating methodologies breeding cultivars high tolerance. Such insights essential developing potential response an increasingly warmer environment.

Agronomic characteristics, mineral nutrient content, antioxidant capacity, biochemical composition, and fatty acid profile of Iranian pistachio (Pistacia vera L.) cultivars

BMC Plant Biology, Год журнала: 2025, Номер 25(1)

Опубликована: Янв. 17, 2025

Pistachio (Pistacia vera L.) nuts are among the most popular nuts. The pistachio cultivars tolerant to both drought and salinity, which is why they extensively grown in arid, saline, hot regions of Middle East, Mediterranean countries, United States. This study evaluated agronomic chemical characteristics 10 ('Abbasiali', 'AhmadAghaei', 'Akbari', 'Chrook', 'Fandoghi', 'KalehGhoochi', 'Momtaz', 'Rezaei', 'Sefied', 'Shahpasand'). Total phenolic content, antioxidant capacity, fruit mineral elements, soluble protein kernel-oil fatty-acid composition were determined 60 fruits (20 per replication). Leaf elements 450 leaves (150 Significant differences observed (p < 0.05) cultivars, with coefficient variation (CV) ranging from 1.03 (unsaturated fatty acids) 115.16% (early nut splitting). Flower buds varied 4 ('AhmadAghaei') 7 ('Momtaz'), bunch ranged 11 ('Abbasiali') 21 ('Momtaz'). Hull percentage 36.8 ('KalehGhoochi') 43.1% ('Chrook'), 56.3 ('Chrook') 62.4% ('KalehGhoochi').

Heat map using Ward clustering revealed cultivar groupings based on traits like nutrient composition. findings obtained this allow producers select suitable for obtaining more efficient high-quality products. Additionally, choosing environmental factors market demands contributes development effective production strategies. ultimate goal provide insights guide selection optimized agricultural sustainability market-specific requirements.

The comprehensive regulatory network in seed oil biosynthesis

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Янв. 17, 2025

ABSTRACT Plant oils play a crucial role in human nutrition, industrial applications and biofuel production. While the enzymes involved fatty acid (FA) biosynthesis are well‐studied, regulatory networks governing these processes remain largely unexplored. This review explores intricate modulating seed oil biosynthesis, focusing on key pathways factors. Seed content is determined by efficiency of de novo FA synthesis as well influenced sugar transport, lipid metabolism, inhibitors fine‐tuning mechanisms. At center this network WRINKLED1 (WRI1), which plays conserved promoting across various plant species. WRI1 interacts with multiple proteins, its expression level regulated upstream regulators, including members LAFL network. Beyond network, we also discuss potential nuclear factor‐Y (NF‐Y) soybean an emphasis NF‐YA NF‐YB their associated proteins. NF‐Y represents promising avenue for future efforts aimed at enhancing accumulation improving stress tolerance soybean. Additionally, application omics‐based approaches great significance. Advances omics technologies have greatly facilitated identification gene resources, opening new opportunities genetic improvement. Importantly, several transcription factors participate responses, highlighting link between two processes. comprehensive elucidates complex mechanisms underlying regulation offering insights into biotechnological strategies production crops.
