Cadmium (Cd) pollution in soil poses a global concern due to its serious impacts on human health and ecological security. In plants, tremendous efforts have been made identify some key genes pathways Cd stress responses. However, studies the roles of epigenetic factors response were still limited. study, we first gain insight into gene expression dynamics for maize seedlings under 0 h, 12 72 h stress. As result, six distinct groups identified by hierarchical clustering principal component analysis. The associated with protein modifications including ubiquitination, signal transduction phosphorylation, histone modification. Whereas, stress, main involved biological processes phenylalanine metabolism, oxygen-containing compounds metal ions. Then be noted, one most highly expressed at treatment is annotated as demethylases (ZmJMJ20). evolutionary tree analysis domain showed that ZmJMJ20 belonged JmjC-only subfamily Jumonji-C (JmjC) family, was conserved rice Arabidopsis. After treatment, zmjmj20 mutant created EMS manifested less severe chlorosis/leaf yellowing symptoms compared wild-type there no significant difference Fv/Fm φPSII value before after treatment. Moreover, levels several photosynthesis-related down-regulated plants dramatically increased those Our results suggested plays an important role tolerance pathway will facilitate development cultivars improved tolerance.

Abstract Background Inter-subspecific hybrid rice represents a significant breakthrough in agricultural genetics, offering higher yields and better resilience to various environmental stresses. While the utilization of these hybrids has shed light on genetic processes underlying hybridization, understanding molecular mechanisms driving heterosis remains complex ongoing challenge. Here, chromatin immunoprecipitation-sequencing (ChIP-seq) was used analyze genome-wide profiles H3K4me3 H3K27me3 modifications inter-subspecific ZY19 its parents, Z04A ZHF1015, then combined them with transcriptome DNA methylation data uncover effects histone gene expression contribution epigenetic heterosis. Results In hybrid, there were 8,126 1,610 different peaks for when compared respectively, majority originating from parental lines. The between parents more frequently observed as levels than parents. ZY19, 476 84 allele-specific genes identified, representing 7.9% 12% total analyzed genes, respectively. Only small portion that showed differences which demonstrated (ASHM) hybrid. modification level significantly lower occurs among target genes. Additionally, over 62.58% differentially expressed (DEGs) affected by variations. Notably, strong correlation variations Conclusion These findings highlight substantial impact during hybridization. Epigenetic play crucial role controlling differential potential implications

Regulation of Plant Translation under Abiotic Stress. A Molecular Orchestration

Опубликована: Май 31, 2023

Stress is one of the important factors affecting growth and development plants. In recent years, a large body data on transcriptional changes in response to stress plants has been obtained. Despite fact that role regulation translation proven plants, knowledge this area remains extremely scarce. review, we focused mRNA cytoplasm higher Most current research effects done yeast mammalian systems. Translation mechanisms are mostly conserved among eukaryotes; however, some differences known exist A comprehensive understanding complex apparatus its required. work, have tried update modern ideas about under conditions abiotic stress.
