The environmental conditions encompassing plants exert a significant impact on their appropriate growth and development. It is of utmost importance to investigate the mechanisms signaling cascades underlying tolerance abiotic stress in order enhance quality crops. Plant development processes are significantly impacted by stresses, which intricately linked surroundings. Plants exhibit prompt genetic metabolic network responses, mostly through networks involving transcription factors that respond stress, including WRKY, MYB, bZIP, AP2/EREBP, NAC. Among these WRKY TFs factors, fulfill pivotal function diverse range responses developmental mechanisms. greatly assist coping with stress. These oversee control several target gene categories active involvement numerous interaction W-box cis-acting elements located promoters genes. This research provides comprehensive analysis response mechanism In addition, we have explored state knowledge TFs' effects plants' such as drought, salt, high temperatures, cold. elucidates intricate molecular govern pathways modulate expression, thereby conferring upon plants. Moreover, summarized involved biotic TFs, hormonal routes like SA JA, aid inducing resistance coordinating defense against pathogens challenges. agricultural sustainability augment crop resilience towards strategies manipulate regulatory need be established.

Deciphering the role of WRKY transcription factors in plant resilience to alkaline salt stress

Plant Stress, Год журнала: 2024, Номер 13, С. 100526 - 100526

Опубликована: Июнь 28, 2024

The WRKY gene family consists of unique transcription factors (TFs) found exclusively in plants. These TFs play a crucial role regulating how plants respond to various abiotic stresses, such as saline-alkaline conditions, temperature fluctuations, drought, UV radiation and others. Scientists have been progressively studying the roles mechanisms several plant species, including both model essential agricultural crops. This study focus has emerged due understanding that alkaline saline soil stressors considerably impede global productivity. Multiple research efforts underscored significant biological functions assisting coping with challenges, particularly enhancing their ability withstand alkaline-salt stress. review aims investigate structural capabilities impact on responses salt stresses. Additionally, it seeks elucidate these alleviating diverse biotic stressors. objective this is provide comprehensive insights into current state field importance

Evolution of the WRKY Family in Angiosperms and Functional Diversity under Environmental Stress

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(6), С. 3551 - 3551

The transcription factor is an essential for regulating the responses of plants to external stimuli. WRKY protein a superfamily plant factors involved in response various stresses (e.g., cold, heat, salt, drought, ions, pathogens, and insects). During angiosperm evolution, number function constantly change. After suffering from long-term environmental battering, different evolutionary statuses ultimately retained numbers family members. proteins generally divided into three large categories angiosperms, owing their conserved domain three-dimensional structures. mediate adaptation environments via participating biological pathways, such as ROS (reactive oxygen species) hormone signaling further enzyme systems, stomatal closure, leaf shrinkage physiological responses. This article analyzed evolution angiosperms its functions responding environments, especially Magnoliaceae plants. It helps gain deeper understanding functional diversity provides theoretical experimental references studying molecular mechanisms stress.

Wild soybean (Glycine soja) transcription factor GsWRKY40 plays positive roles in plant salt tolerance

The Crop Journal, Год журнала: 2024, Номер 12(3), С. 766 - 775

Опубликована: Май 3, 2024

Wild soybean (Glycine soja), a relative of cultivated soybean, shows high adaptability to adverse environmental conditions. We identified and characterized wild transcription factor gene, GsWRKY40, that promotes plant salt stress. GsWRKY40 was highly expressed in roots up-regulated by treatment. localized nucleus demonstrated DNA-binding activities but without transcriptional activation. Mutation overexpression altered tolerance Arabidopsis plants. To understand the molecular mechanism regulating resistance, we screened cDNA library interacting protein GsbHLH92 using yeast two-hybrid approach. The physical interaction confirmed co-immunoprecipitation (co-IP), GST pull-down, bimolecular fluorescence complementation (BiFC) techniques. Intriguingly, co-overexpression resulted higher lower ROS levels than or composite plants, suggesting may synergistically regulate resistance through inhibiting production. qRT-PCR data indicated expression level GmSPOD1 gene encoding peroxidase cooperatively regulated GsbHLH92, which dual luciferase report system one-hybrid experiment. Our study reveals pathway collaboratively up-regulate impeding reducing levels, providing novel perspective on regulatory mechanisms underlying abiotic stresses

Natural variation of OsWRKY23 drives difference in nitrate use efficiency between indica and japonica rice

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Фев. 6, 2025

Between the two major rice subspecies, indica varieties generally exhibit higher nitrate (NO3‒) uptake and nitrogen (N)-use efficiency (NUE) than japonica varieties. Introducing efficient NO3‒ utilization alleles from into could improve NUE, at same time uncover unknown regulators of metabolism. Here, we identify OsWRKY23 as a key regulator NUE differences between rice. The OsWRKY23indica allele exhibits reduced transcriptional activation negative auxin accumulation, DULL NITROGEN RESPONSE1 (DNR1). resultant increase in level improves assimilation, which ultimately enhances grain yield. Geographical evolutionary analyses reveal overlapping distribution DNR1indica, particularly low-fertility soils, suggesting their involvement adaptation to low N conditions Incorporating OsWRKY23-DNR1 module represents promising strategy enhance is crucial for sustainable agriculture. Rice have use that authors show natural variation its interaction with (DNR1)-mediated accumulation play role divergence subspecies.
