The present study investigated rice leaf proteome in response to heat stress. Rice seedlings were subjected a temperature of 42 degrees C and samples collected 12 24 h after treatment. Increased relative ion leakage lipid peroxidation suggested that oxidative stress frequently was generated leaves exposed high temperature. 2-DE, coupled with MS, used investigate identify heat-responsive proteins leaves. In order the low-abundant leaves, prefractionated by 15% PEG. PEG supernatant pellet...
Abstract While the phytotoxic responses of arsenic (As) on plants have been studied extensively, based physiological and biochemical aspects, very little is known about As stress‐elicited changes in at proteome level. Hydroponically grown 2‐wk‐old rice seedlings were exposed to different doses arsenate, roots collected after 4 days treatment, as well a recovery period. To gain comprehensive understanding precise mechanisms underlying toxicity, metabolism, defense reactions plants,...
The C(4)-Pdk gene encoding the C(4) enzyme pyruvate, orthophosphate dikinase (PPDK) of maize (Zea mays cv Golden Cross Bantam) was introduced into C(3) plant, rice (Oryza sativa Kitaake). When intact gene, containing its own promoter and terminator sequences exon/intron structure, introduced, PPDK activity in leaves some transgenic lines greatly increased, one line reaching 40-fold over that wild-type plants. In a homozygous line, protein accounted for 35% total leaf-soluble or 16% leaf...
Nitric oxide (NO) is a signaling molecule that regulates various processes, including plant growth and development, immunity, environmental interactions. Using high throughput RNA-seq data, we explored the role of NO-induced ATILL6 gene in defense using functional genomics. The atill6 mutant wild-types were challenged with either oxidative (H 2 O , MV) or nitro-oxidative (CySNO, GSNO) stress conditions, phenotypic results showed differentially cotyledon development frequency (CDF) as well...
Previously, we identified >1,500 genes that were induced by high salt stress in sheepgrass (Leymus chinensis, Gramineae: Triticeae) when comparing the changes their transcription levels response to next-generation sequencing. Among genes, a gene of unknown function (designated as Leymus chinensis salt-induced 1, LcSAIN1) showed sequence identity its homologs from wheat, Hordeum vulgare and Oryza sativa, but LcSAIN1 produce hypothetical proteins with no conserved functional domains....
The cloning and characterization of a gene (MsHSP23) coding for heat shock protein in alfalfa prokaryotic model plant system is described. MsHSP23 contains 633 bp ORF encoding polypeptide 213 amino acids exhibits greater sequence similarity to mitochondrial sHSPs from dicotyledons than those monocotyledons. When expressed bacteria, recombinant conferred tolerance salinity arsenic stress. Furthermore, was cloned expressing vector transformed into tobacco, eukaryotic organism. transgenic...
To evaluate the response of alfalfa to water deficit (WD) stress, WD-induced candidates were investigated through a proteomic approach. Alfalfa seedlings exposed WD stress for 12 and 15 days respectively, followed by 3 re-watering. Water increased H2O2 content, lipid peroxidation, DPPH (1,1-diphenyl-2-picrylhydrazyl)-radical scavenging activity, free proline level in roots. Root proteins extracted separated two-dimentional polyacrylamide gel electrophoresis (2-DE). A total 49 WD-responsive...
