Soil salinity has become an increasingly serious problem worldwide, greatly limiting crop development and yield, posing a major challenge to plant breeding. Basic leucine zipper (bZIP) transcription factors are the most widely distributed conserved main regulators controlling various response processes against external stimuli. The bZIP protein contains two domains: highly conserved, DNA-binding alkaline region, diverse zipper, which is one of largest factor families in plants. Plant involved many biological processes, such as flower development, seed maturation, dormancy, senescence, plays important role abiotic stresses salt damage, drought, cold osmotic stress, mechanical ABA signal response. In addition, regulation insect pests pathogen infection through salicylic acid, jasmonic transduction pathways.

SWITCH deficient SUCROSE NONFERMENTING (SWI/SNF) class chromatin remodeling complexes (CRCs) use the energy derived from ATP hydrolysis to facilitate access of proteins genomic DNA for transcription, replication, and repair. Uniquely, SWI/SNF CRCs can both slide histone octamer along or eject it DNA. Given their ability change status quo, remodelers are critical cell fate reprogramming with pioneer other transcription factors, responses environmental challenges, disease prevention. Recent cryo-electron microscopy mass spectrometry approaches have uncovered different subtypes unique properties functions. At same time, tethering rapid depletion inactivation provided novel insight into requirements enhancer activity balancing compaction accessibility in concert Polycomb complexes. importance, recruitment locations by factors biochemical is tightly controlled.

Transcription factors (TFs) are diverse groups of regulatory proteins. Through their specific binding domains, TFs bind to target genes and regulate expression, therefore play important roles in various growth developmental processes. Plant embryogenesis is a highly regulated intricate process during which embryos arise from sources undergo development; it can be further divided into zygotic (ZE) somatic (SE). crucial role the plant with number them acting as master regulators both ZE SE. In this review, we focus on involved such BABY BOOM (BBM) APETALA2 / Ethylene-Responsive Factor (AP2/ERF) family, WUSCHEL WUSCHEL-related homeobox (WOX) LEAFY COTYLEDON 2 (LEC2) B3 AGAMOUS-Like 15 (AGL15) MADS family 1 (LEC1) Nuclear Y (NF-Y) family. We aim present recent progress pertaining these SE Arabidopsis, well other species including crops. also discuss future perspectives context.

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.

Double DAP-seq uncovered synergistic DNA binding of interacting bZIP transcription factors

Nature Communications, Год журнала: 2023, Номер 14(1)

Abstract Many eukaryotic transcription factors (TF) form homodimer or heterodimer complexes to regulate gene expression. Dimerization of BASIC LEUCINE ZIPPER (bZIP) TFs are critical for their functions, but the molecular mechanism underlying DNA binding and functional specificity homo- versus heterodimers remains elusive. To address this gap, we present double Affinity Purification-sequencing (dDAP-seq) technique that maps sites on endogenous genomic DNA. Using dDAP-seq profile twenty pairs C/S1 bZIP S1 homodimers in Arabidopsis show heterodimerization significantly expands preferences these TFs. Analysis reveals function bZIP9 abscisic acid response role bZIP53 heterodimer-specific seed maturation. The distinct ACGT elements recognized by plant bZIPs motifs resembling yeast GCN4 cis -elements. This study demonstrates potential deciphering specificities interacting key combinatorial regulation.

Untranslated yet indispensable—UTRs act as key regulators in the environmental control of gene expression

Journal of Experimental Botany, Год журнала: 2024, Номер 75(14), С. 4314 - 4331

Опубликована: Фев. 22, 2024

Abstract To survive and thrive in a dynamic environment, plants must continuously monitor their surroundings adjust development physiology accordingly. Changes gene expression underlie these developmental physiological adjustments, are traditionally attributed to widespread transcriptional reprogramming. Growing evidence, however, suggests that post-transcriptional mechanisms also play vital role tailoring plant’s environment. Untranslated regions (UTRs) act as regulatory hubs for control, harbouring cis-elements affect an mRNA’s processing, localization, translation, stability, thereby tune the abundance of encoded protein. Here, we review recent advances made understanding critical function UTRs exert control context abiotic We summarize molecular at play, present examples UTR-controlled signalling cascades, discuss potential resides within render more resilient changing climate.
