H2O2 is known as a signal molecule in plant cells, but its role the regulation of aqbscisic acid (ABA) and gibberellic (GA) metabolism hormonal balance not yet clear. In this study it was found that affected ABA catabolism GA biosynthesis during seed imbibition thus exerted control over dormancy germination. As seen by quantitative RT-PCR (QRT-PCR), up-regulated genes (e.g. CYP707A genes), resulting decreased content imbibition. This action required participation nitric oxide (NO), another...
Both glucose and ABA play crucial roles in the regulation of seed germination post-germination development. In Arabidopsis thaliana, up-regulation biosynthesis is suggested as one possible mechanisms mediating glucose-induced delay germination. Since endogenous level controlled by equilibrium between catabolism, we investigated how this related to rice. When was inhibited nordihydroguaiaretic acid (NDGA), an inhibitor anabolic enzyme 9-cis-epoxycarotenoid dioxygenase (NCED), rice showed no...
The production of both ABA and H2O2 is induced by drought can act as signals under stress conditions. We investigated the relationships between ABA, catalase (CAT) in rice leaves when seedlings were treated with polyethylene glycol water treatment. As a key gene biosynthesis, OsNCED3 was significantly treatment such induction preceded rapid increase ABA. Water inhibited expression CATA CATC but substantially enhanced CATB. Exogenously applied promoted CATB also concentration-dependent...
The role of ABA in brassinosteroid (BR)-induced stress tolerance and the relationship between BR, nitric oxide (NO) under water induced by polyethylene glycol (PEG) were investigated leaves maize (Zea mays) plants. Water led to oxidative damage. Pre-treatment with BR biosynthetic inhibitor brassinazole (Brz) aggravated damage PEG treatment, which was alleviated application or ABA. fluridone also treatment; however, this barely BR. treatment increased content up-regulated expression gene vp14...
Later-flowering spikelets in a rice panicle, referred to as the inferior spikelets, are usually poorly filled and often limit yield potential of some cultivars. The physiological molecular mechanism for such poor grain filling remains unclear. In this study differentially expressed genes starch synthesis hormone signalling between superior were comprehensively analysed their relationships with was investigated. DNA microarray real-time PCR analysis revealed that group metabolism-related...
The antagonism between abscisic acid (ABA) and gibberellin (GA) plays a key role in controlling seed germination, but the mechanism of during this process is not known. possible links among ABA, reactive oxygen species (ROS), ascorbic (ASC), GA rice germination were investigated. Unlike non-seed tissues where ROS production increased by ABA reduced imbibed seeds, especially embryo region. Such also led to an inhibition ASC production. accumulation was suppressed level, which indicated...
Nitric oxide (NO) has been reported to be involved in breaking seed dormancy but its mechanism of action is unclear. Here, we report that a rapid accumulation NO induced an equally decrease abscisic acid (ABA) required for this Arabidopsis. Results quantitative real-time polymerase chain reaction (QRT-PCR) and Western blotting indicate the NO-induced ABA correlates with regulation CYP707A2 transcription (+)-abscisic 8'-hydroxylase (encoded by CYP707A2) protein expression. By analysing...
In eukaryotes, mechanisms such as alternative splicing (AS) and translation initiation (ATI) contribute to organismal protein diversity. Specifically, factors play crucial roles in responses environment development cues; however, the underlying are not well investigated plants. Here, we report parallel employment of short-read RNA sequencing, single molecule long-read sequencing proteomic identification unravel AS isoforms previously unannotated proteins response abscisic acid (ABA)...
Brassinosteroids (BRs) have been shown to induce hydrogen peroxide (H2O2) accumulation, and BR-induced H2O2 up-regulates antioxidant defence systems in plants. However, the mechanisms by which regulates plants remain be determined. In present study, role of ZmMPK5, a mitogen-activated protein kinase, anitioxidant relationship between activation ZmMPK5 production BR signalling were investigated leaves maize (Zea mays) treatment activated induced apoplastic chloroplastic enhanced total...
The NAC (NAM, AFAT, and CUC) transcription factors play critical roles in rice (Oryza sativa) development stress regulation. Overexpressing a microRNA (miR164b)-resistant OsNAC2 mutant gene, which generates transcripts that cannot be targeted by miR164b, improves plant architecture yield; however, the performance of these mOsNAC2-overexpressing lines, named ZUOErN3 ZUOErN4, under abiotic conditions such as drought have not yet been fully characterized.In this study, we showed germination...
Expressions of ABA biosynthesis genes and catabolism are generally co-regulated in plant development responses to environmental stress. Up-regulation OsNCED3 gene, a key gene biosynthesis, has been suggested as way enhance drought resistance but little is known for the role catabolic during In this study, we found that OsABA8ox3 was most highly expressed OsABA8ox family rice leaves. Expression promptly induced by rehydration after PEG-mimic dehydration, tendency opposite changes level. We...
Root architecture development, an agronomic trait that influences crop yield, is regulated by multiple plant hormones. Abscisic acid (ABA) a stress hormone responds to stresses, including salt, drought, and cold stress, modulates various aspects of growth development. In recent years, it has been found ABA synthesized under mild or well-watered conditions can support resistance positively regulating root this review, we summarize the molecular, cellular, organismal basis homeostasis in how...
Oxalate is widely distributed in the plant kingdom. While excess oxalate food crops detrimental to animal and human health, it may play various functional roles plants, particularly for coping with environmental stresses. Understanding its biosynthetic mechanism therefore, becomes increasingly important both theoretically practically. However, still a matter of debate as what precursor pathway are ultimately used biosynthesis plants. In this study, physiological molecular approaches were...
Soil alkalinity is a widespread environmental problem that limits agricultural productivity. The hypothesis an auxin-regulated proton secretion by plasma membrane H+-ATPase plays important role in root adaption to alkaline stress was studied. It found increased auxin transport and PIN2 (an efflux transporter) abundance the tip of wild-type Arabidopsis plants (WT). Compared with WT roots, pin2 mutant roots exhibited much reduced activity, elongation, transport, under stress. More importantly,...
Proanthocyanidins (PAs) are the main products of flavonoid biosynthetic pathway in seeds, but their biological function during seed germination is still unclear. We observed that delayed with increase exogenous PA concentration Arabidopsis. A similar inhibitory effect occurred peeled Brassica napus which was by measuring radicle elongation. Using abscisic acid (ABA), a and metabolic inhibitor, gene expression analysis real-time polymerase chain reaction, we found PAs on due to promotion ABA...
Post-transcriptional mechanisms (PTMs), including alternative splicing (AS) and translation initiation (ATI), may explain the diversity of proteins involved in plant development stress responses. Transcriptional regulation is important during hypoxic germination rice seeds, but potential roles PTMs this process have not been characterized. We used a combination proteomics RNA sequencing to discover how AS ATI contribute responses hypoxia. In total, 10 253 intron-containing genes were...
Rice (Oryza sativa) molecular breeding has gained considerable attention in recent years, but inaccurate genome annotation hampers its progress and functional studies of the rice genome. In this study, we applied single-molecule long-read RNA sequencing (lrRNA_seq)-based proteogenomics to reveal complexity transcriptome coding abilities. Surprisingly, approximately 60% loci identified by lrRNA_seq are associated with natural antisense transcripts (NATs). The high-density genomic arrangement...
