Sucrose non-fermenting 2 (Snf2) protein family, as chromatin remodeling factors, is an enormous and the most diverse which contributes to biological processes of replication, transcription, DNA repair using energy adenosine triphosphate (ATP) hydrolysis. The members Snf2 family proteins have been well characterized in Arabidopsis, rice, tomato. Although this received significant attention, few genes were identified uniquely for their roles mediating reproductive development stress tolerance rice. In present study, we comprehensively analyzed expression profiling during biotic/abiotic stresses. Our results showed that five (OsCHR712/715/720/726/739) mainly localized nucleus, while OsCHR715/739 also slightly expressed cell membrane. There abundant cis-acting elements putative promoter genes, including dehydration, MeJA, MYB binding site drought, ABA-responsive, stress-responsive element. Most induced immediately after Magnaporthe oryzae infection at 12 h post-infection (hpi). About 55% total upregulated under salt drought stresses entire time, 22-35% 3 h. It was noteworthy seven (OsCHR705, OsCHR706, OsCHR710, OsCHR714, OsCHR721, OsCHR726, OsCHR737) upregulated, one gene (OsCHR712) downregulated stresses, respectively. deficiency OsCHR726 mutations displayed a hypersensitive phenotype stress. These will be significantly useful features validation rice facilitate understanding genetic engineering crops with improved biotic abiotic

Plants have evolved adaptive strategies to cope with pathogen infections that seriously threaten plant viability and crop productivity. Upon the perception of invading pathogens, immune system is primed, establishing an memory allows primed plants respond more efficiently upcoming attacks. Physiological, transcriptional, metabolic, epigenetic changes are induced during defense priming, which essential establishment maintenance memory. As environmental-friendly technique in protection, seed priming could effectively induce In this review, we highlighted recent advances mechanisms associated, discussed challenges exploiting on crops enhance disease resistance.

Climate change-related environmental stresses can negatively impact crop productivity and pose a threat to sustainable agriculture. Plants have remarkable innate ability detect broad array of cues, including that trigger stress-induced regulatory networks signaling pathways. Transcriptional activation plant pathogenesis related-1 (PR-1) proteins was first identified as an integral component systemic acquired resistance in response stress. Consistent with their central role immune defense, overexpression PR-1s diverse species is frequently used marker for salicylic acid (SA)-mediated defense responses. Recent advances demonstrated how virulence effectors, SA cascades, epigenetic modifications modulate PR-1 expression stresses.

Abstract The genome folds into complex configurations and structures thought to profoundly impact its function. intricacies of this dynamic structure-function relationship are not well understood particularly in the context viral infection. To unravel interplay, here we provide a comprehensive investigation simultaneous host chromatin structural (via Hi-C ATAC-seq) functional changes RNA-seq) response vaccinia virus Over time, infection significantly impacts global local structure by increasing long-range intra-chromosomal interactions B compartmentalization decreasing accessibility inter-chromosomal interactions. Local independent broad-scale compartment exchange (~12% genome), underscoring potential mechanisms for reorganization. While structurally condenses genome, there is nearly equal bidirectional differential gene expression.

Crop adaptation to climate change is in a part attributed epigenetic mechanisms which are related response abiotic and biotic stresses. Although recent studies increased our knowledge on the nature of these mechanisms, epigenetics remains under-investigated still poorly understood many, especially non-model, plants, Epigenetic modifications traditionally divided into two main groups, DNA methylation histone that lead chromatin remodeling regulation genome functioning.

Golden leaf in autumn is a prominent feature of deciduous tree species like Ginkgo biloba L., landscape widely cultivated worldwide. However, little was known about the molecular mechanisms yellowing, especially its dynamic regulatory network. Here, we performed suite comparative physiological and transcriptional analyses on golden-leaf cultivar wild type (WT) ginkgo to investigate underlying yellowing across different seasons.In present study, used natural bud mutant with yellow leaves "Wannianjin" (YL) as materials. Physiological analysis revealed that higher ratios chlorophyll b carotenoid caused YL. On other hand, transcriptome showed genes related metabolism played key role coloration. Genes encoding non-yellow coloring 1 (NYC1), NYC1-like (NOL), chlorophyllase (CLH) involved degradation were up-regulated spring. At summer stage, down-regulated HEMA glutamyl-tRNA reductase functioned biosynthesis, while CLH up-regulated, causing lower accumulation. In metabolism, zeaxanthin epoxidase (ZEP) 9-cis-epoxy dioxygenase (NCED) significantly expression levels WT Moreover, weighted gene co-expression network (WGCNA) suggested most associated factor, which belongs AP2/ERF-ERF family, engaged regulating pigment metabolism. Furthermore, quantitative experiments validated above results.By comparing wide three seasons, this study not only confirm vital coloration YL but also provided new insights into seasonal Our novel results pinpoint candidate for further wet-bench species.
