In this study, we aimed to investigate the heat tolerance mechanism in Rhododendron henanense subsp. lingbaoense (Rhl). Rhl seedlings were treated at 40℃ (RLH), 32℃ (RLM), and 24℃ (RLC), changes transcriptome metabolome compared. Overall, 78 differentially expressed metabolites detected, 8450 genes (DEGs) identified. KEGG analysis revealed that DEGs RLH vs. RLC mainly enriched photosynthesis, secondary metabolic biosynthesis, flavonoid biosynthesis. Most encoding glutathione-S-transferase upregulated, whereas related shock proteins significantly downregulated. 31 photosynthesis upregulated (P-value < 0.001). It was speculated these are response of high temperature stress (HTS). 9 TF families might be key regulators Heat pathways Rhl. Mining expression some function increased highly significantly, e.g., Rhe008987 Glutathione-S-transferase, Rhe016769 peroxidase, Rhe001827 chalcone stilbene synthases. Metabolome correlation three comparison groups (RLH RLC, RLM, RLM RLC) shared 12 which DEMs enriched. HTS inhibited or induced biosynthesis pathway led decreace kaempferol content quercetin accumulation. HT ABC pathway, may one reasons for significant accumulation L-isoleucine, L-leucine, L-proline. mining found significantly. And two omics groups. These results helped elucidating molecular mechanisms HTS.

Silicate solubilizing and plant growth promoting bacteria interact with biogenic silica to impart heat stress tolerance in rice by modulating physiology and gene expression

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Heat stress caused due to increasing warming climate has become a severe threat global food production including rice. Silicon plays major role in improving growth and productivity of rice by aiding alleviating heat Soil silicon is only sparingly available the crops can be made silicate solubilizing plant-growth-promoting bacteria that possess capacity solubilize insoluble silicates increase availability soluble soil. In addition, plant promoting are known enhance tolerance abiotic stresses plants, affecting biochemical physiological characteristics plants. The present study intended understand beneficial viz. Rhizobium sp. IIRR N1 solublizer Gluconacetobacter diazotrophicus , their interaction with sources on morpho-physiological molecular attributes ( Oryza sativa L.) seedlings after exposure controlled hydroponic system. Joint inoculation both increased content tissue, root shoot biomass, significantly antioxidant enzyme activities (viz. superoxidase dismutase, catalase ascorbate peroxidase) compared other treatments sole application either or bacteria. traits chlorophyll content, relative water content) were also found enhanced presence conditions. Expression profiling tissues revealed grown exhibited higher expression shock proteins (HSPs viz., OsHsp90 OsHsp100 60 kDa chaperonin ), hormone-related genes OsIAA6 ) transporters OsLsi1 OsLsi2 as treated alone. results thus reveal interactive effect combined along N1, G. not led augmented uptake but influenced biomass elicited HSPs, transporter leading improved seedling stress.

Increasing the resistance of the hollyhock plant to cold stress: silicon or selenium

Journal of Plant Nutrition, Год журнала: 2024, Номер 47(7), С. 1110 - 1129

It is well-known that freezing affects crop growth worldwide and significantly reduces production in the affected regions. The study objective was to investigate effect of sodium silicate selenite individually or combination on Alcea rosea plants grown under cold temperature stress. In this work, hollyhock were with 1/2 Hoagland solution, including 1) control, 1 mM sulfate, 2) 3), 0.03 selenite, 4) + exposed nonfreezing (20 °C) (−4 °C). Nutritional elements, photosynthesis parameters, electrolyte leakage, malondialdehyde, water content, osmolytes, antioxidant enzymes determined. application Si Se effectively enhanced content leaves (54% 164%) compared control plants. combined addition increased phenols, water-soluble sugars, proline, chlorophyll, net (Pn), stomatal size Moreover, stressed inhibited leakage malondialdehyde (MDA) by increasing activities such as superoxidase dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT). maximal minimal values essential oil relative (RWC), density depended treatment: > = Se. By K phenol, decreased adverse effects stress dry weight hollyhock.

Soil salinity and alkalinity present a serious threat to global agriculture.The objective of this study is elucidate candidate genes associated with salt stresses in maize plant tissues through the utilization transcriptome transgene methods.Specifically, 8723 P138 cultivars were employed as salt-tolerant salt-sensitive materials, respectively.To verify tolerance materials screen best stress experimental concentration, different concentrations treatment carried out.Then, analysis was performed based on sequence data seedlings related identified.The findings revealed that high significantly inhibited germination characteristics seedling growth maize.Notably, gene expression profiles response differed between two inbred lines during stage.After functional enrichment co-expression interaction network analysis, we found ZmHSP20 key tolerance.In order further function ZmHSP20, constructed overexpression lines.The results showed carrying tobaccos more tolerant than wild-type (WT).Additionally, activity antioxidant enzymes higher tobacco WT.This lays groundwork for research aspects presents an initial exploration its role conferring resistance stress.Further investigations are required reveal mechanism by which regulates against tobacco.
