Proline metabolism influences the metabolic and/or signaling pathway in regulating plant stress responses. This study aimed to characterize physiological significance of glutamate (Glu)-mediated proline drought responses, focusing on hormonal regulatory pathway. The responses cytosolic Ca2+ signaling, metabolism, and redox components exogenous application Glu well-watered or drought-stressed plants were interpreted relation endogenous hormone status their genes. Drought-enhanced level...
Introduction/Objective Soybean is a major source of various nutrients. Increasing demand for soybeans has created considerable impetus exploring the nutritional quality soybeans. We aimed to collect soybean varieties rich in Materials and Methods Metabolite analysis was carried out seed compositions, including protein, phenolics, flavonoids, along with gene expression protein phenolic metabolism-related enzymes 10 accessions collected from different geographical regions. Results Total...
The aim of this study was to characterize hormonal crosstalk with the sugar signaling and metabolic pathway based on a time course analysis drought intensity. Drought intensity-responsive changes in assimilation newly fixed carbon (C) into soluble sugar, content starch, expression genes involved carbohydrate metabolism were interpreted as being linked endogenous abscisic acid (ABA) salicylic (SA) levels their genes. ABA SA drought-stressed leaves increased together during early period (days...
Abstract Crosstalk between hormones and secondary metabolites regulates the interactions plants stress. However, little is known about effects of hormone crosstalk on concentration flavonoids in seeds. In this study, we identified abscisic acid (ABA) as a negative regulator flavonoid accumulation soybean seeds under drought‐stress conditions. Alterations at several intensities water stress, followed by recovery period, were measured during seed‐filling stage. Low soil moisture (SM 10%)...
This study aimed to directly elucidate cultivar variation in disease susceptibility and responses relation hormonal status the interaction of Brassica napus cultivars Xanthomonas campetris pv. campestris (Xcc), causal agent black rot disease. Fully expanded leaves six B. (cvs. Capitol, Youngsan, Saturnin, Colosse, Tamra, Mosa) were inoculated with Xcc. At 14 d post-inoculation (dpi) Xcc, or resistance was interpreted defense as estimated by redox status, defensive metabolites, expression...
Drought alters the level of endogenous reactive oxygen species (ROS) and hormonal status, which are both involved in regulation stress responses. To investigate interplay between ROS hormones proline metabolism, rapeseed (Brassica napus L.) plants were exposed to drought or exogenous H2O2 (Exo-H2O2) treatment for 10 days. During first 5 days, enhanced concentrations associated with activation superoxide dismutase (SOD) NADPH oxidase, ABA SA levels, while that Exo-H2O2 was mainly...
To characterize cultivar variation in resistance gene (R-gene)-mediated calcium signaling and hormonal regulation effector-triggered immunity (ETI) disease susceptibility, Xanthomonas campestris pv. (Xcc) was inoculated two Brassica napus cultivars (cvs. Capitol Mosa). At 14 days post inoculation (DPI) with Xcc, there a necrotic lesion cv. Mosa along the significant accumulation of H2O2 malondialdehyde (MDA), whereas no visual symptom observed Capitol. The variations R-gene expressions were...
The leaf senescence process is characterized by the degradation of macromolecules in mature leaves and remobilization products via phloem transport. phytohormone ethylene mediates senescence. This study aimed to investigate ethephon-induced effects on starch sucrose through their interactive regulation with other hormones. Ethephon (2-chloroethylphosphonic acid) was used as an ethylene-generating agent. Endogenous hormonal status, carbohydrate compounds, degradation-related gene expression,...
Senescence is modulated by ORESARA1 (ORE1), a NAC transcription factor that interacts with hormones to fully induce senescence. The At-ore1 gene acts as suppressor of leaf senescence; however, its exact role in this respect has not been clearly defined. In study, the function during senescence was analyzed soybeans. precocious ore1-1 line associated greater chlorophyll loss, necrosis, and redox imbalance early vegetative stage hyper-accumulation endogenous abscisic acid (ABA) enhancing...
Abstract Oilseed rape ( Brassica napus L.) is a significant agro‐economic crop with wide range of uses. Drought the most frequent unfavourable environmental stressor restraining its growth and development worldwide. This study was conducted to characterize drought‐responsive phenylpropanoid pathway link hormonal changes in two cultivars, drought‐resistant “Saturnin” drought‐susceptible “Mosa.” susceptibility cv. Mosa confirmed by lower water use efficiency higher lipid peroxidation levels...
In plants, prolonged drought induces oxidative stress, leading to a loss of reducing potential in redox components. Abscisic acid (ABA) is representative hormonal signal regulating stress responses. This study aimed investigate the physiological significance dimethylthiourea (DMTU, an H2O2 scavenger) regulation antioxidant system and control rapeseed (Brassica napus L.) leaves under stress. Drought treatment for 10 days provoked as evidenced by increase O2•- concentrations, lipid...
Drought intensity modifies the assimilatory pathway of glutathione (GSH) synthesis. Abscisic acid (ABA) is a representative signaling hormone involved in regulating plant stress responses. This study aimed to investigate an interactive regulation sulfate and/or ABA GSH metabolism and redox. The drought-responsive alterations assimilation GSH-based redox reactions were assessed relative responses on time-course drought intensity. Drought-responsive H
To investigate the regulatory role of ethylene in source-sink relationship for nitrogen remobilization, short-term effects treatment with different concentrations (0, 25, 50, and 75 ppm) ethephon (2-chloroethylphosphonic acid, an inducing agent) 10 days (EXP 1) long-term at 20 (Day 30) after 100 ppm 2) on protein degradation amino acid transport foliar sprayed mature leaves Brassica napus (cv. Mosa) were determined. In EXP 1, endogenous concentration gradually increased response to treated...
Black rot, caused by Xanthomonas campestris pv. (Xcc), is the main disease of cruciferous vegetables. To characterize resistance mechanism in Brassica napus–Xcc pathosystem, Xcc-responsive proteins susceptible (cv. Mosa) and resistant Capitol) cultivars were investigated using gel-free quantitative proteomics analysis gene expression. This allowed us to identify 158 163 differentially expressed following Xcc infection cv. Mosa Capitol, respectively, classify them into five major categories...
