Reactive oxygen species (ROS) are produced as undesirable by-products of metabolism in various cellular compartments, especially response to unfavorable environmental conditions, throughout the life cycle plants. Stress-induced ROS production disrupts normal function and leads oxidative damage. To cope with excessive ROS, plants equipped a sophisticated antioxidative defense system consisting enzymatic non-enzymatic components that scavenge or inhibit their harmful effects on biomolecules. Nonetheless, when maintained at relatively low levels, act signaling molecules regulate plant growth, development, adaptation adverse conditions. Here, we provide an overview current approaches for detecting ROS. We also discuss recent advances understanding signaling, metabolism, roles growth responses abiotic stresses.

SUMMARY Global climate change is predicted to result in increased yield losses of agricultural crops caused by environmental conditions. In particular, heat and drought stress are major factors that negatively affect plant development reproduction, previous studies have revealed how these stresses induce responses at physiological molecular levels. Here, we provide a comprehensive overview current knowledge concerning drought, heat, combinations conditions the status plants, including crops, affecting such as stomatal conductance, photosynthetic activity, cellular oxidative conditions, metabolomic profiles, signaling mechanisms. We further discuss stress‐responsive regulatory transcription factors, which play critical roles adaptation both potentially function ‘hubs’ and/or responses. Additionally, present recent findings based on forward genetic approaches reveal natural variations traits under Finally, an application decades study results actual fields strategy increase tolerance.

Abstract Modern green revolution varieties of wheat ( Triticum aestivum L.) confer semi-dwarf and lodging-resistant plant architecture owing to the Reduced height-B1b Rht-B1b ) Rht-D1b alleles 1 . However, both are gain-of-function mutant encoding gibberellin signalling repressors that stably repress growth negatively affect nitrogen-use efficiency grain filling 2–5 Therefore, harbouring or usually produce smaller require higher nitrogen fertilizer inputs maintain their yields. Here we describe a strategy design without need for alleles. We discovered absence Rht-B1 ZnF-B (encoding RING-type E3 ligase) through natural deletion haploblock about 500 kilobases shaped plants with more compact substantially improved yield (up 15.2%) in field trials. Further genetic analysis confirmed induced trait attenuating brassinosteroid (BR) perception. ZnF acts as BR activator facilitate proteasomal destruction repressor BRI1 kinase inhibitor (TaBKI1), loss stabilizes TaBKI1 block transduction. Our findings not only identified pivotal modulator but also provided creative high-yield by manipulating signal pathway sustain production.

Abstract Poaceae members shared a whole-genome duplication called rho. However, little is known about the evolutionary pattern of rho-derived duplicates among lineages and implications in adaptive evolution. Here we present phylogenomic/phylotranscriptomic analyses 363 grasses covering all 12 subfamilies report nine previously unknown duplications. Furthermore, duplications from single were mapped to multiple nodes on species phylogeny; was likely by woody bamboos with possible gene flow herbaceous bamboos; recent paralogues tetraploid Oryza are implicated tolerance seawater submergence. Moreover, rho showing differential retention include those functions environmental adaptations or morphogenesis, including ACOT for aquatic environments (Oryzoideae), CK2β cold responses (Pooideae), SPIRAL1 rapid cell elongation (Bambusoideae), PAI1 drought/cold (Panicoideae). This study presents profile evidence mechanisms that contribute losses.

Global climate change has great impacts on plant growth and development, reducing crop productivity worldwide. Rice (Oryza sativa L.), one of the world's most important food crops, is susceptible to high-temperature stress from seedling stage reproductive stage. In this review, we summarize recent advances in understanding molecular mechanisms underlying heat responses rice, including sensing signalling, transcriptional regulation, transcript processing, protein translation, post-translational regulation. We also highlight irreversible effects high temperature reproduction grain quality rice. Finally, discuss challenges opportunities for future research

Abstract As a result of global warming, plants are subjected to ever-increasing abiotic stresses including heat and drought. Drought stress frequently co-occurs with as water evaporation. These stressors have adverse effects on crop production, which in turn affects human food security. Rice is major resource grown widely crop-producing regions throughout the world. However, increasingly common drought growth can negative impacts seedling morphogenesis, reproductive organ establishment, overall yield, quality. This review centers responses rice. Current knowledge molecular regulation mechanisms summarized. We focus approaches cope stress, both at genetic level from an agricultural practice perspective. establishes basis for improving rice tolerance, grain quality, yield benefit.

Chloroplasts are the defining plant organelles with responsibility for photosynthesis and other vital functions. To deliver these functions, they possess a complex proteome comprising thousands of largely nucleus-encoded proteins. Composition is controlled by diverse processes affecting protein translocation degradation—our focus here. Most chloroplast proteins imported from cytosol via multiprotein translocons in outer inner envelope membranes (the TOC TIC complexes, respectively), or one several noncanonical pathways, then sorted different systems to organellar subcompartments. Chloroplast proteolysis equally complex, involving concerted action internal proteases prokaryotic origin nucleocytosolic ubiquitin–proteasome system (UPS). The UPS degrades unimported chloroplast-resident chloroplast-associated degradation (CHLORAD). latter targets apparatus regulate import, as well numerous directly, reconfigure functions response developmental environmental signals.
