Studies in yeast and animals have revealed that histone deacetylases (HDACs) often act as components of multiprotein complexes, including chromatin remodelling complexes (CRCs). However, interactions between HDACs CRCs plants yet to be demonstrated. Here, we present evidence for the interaction Arabidopsis HD2C deacetylase a BRM-containing SWI/SNF CRC. Moreover, reveal novel function regulator heat stress response. transcript levels were strongly induced subjected treatment, expression...
Abstract Germination and early seedling development are critical for successful stand establishment of plants. Following germination, the cotyledons, which derived from embryonic tissue, emerge seed. Arabidopsis seedlings at post-germinative stages supported mainly by supply nutrition cotyledons until vegetative leaves initiate photosynthesis. The switch to autotrophic growth is a significant transition stage. Here, we provide evidence that down-regulation SQUAMOSA PROMOTER-BINDING PROTEIN...
Abstract MicroRNAs (miRNAs) are involved in developmental programmes of plants, including seed germination and post-germination. Here, we provide evidence that two different miRNA pathways, miR156 miR172, interact during the post-germination stages Arabidopsis . Mutant seedlings expressing miR156-resistant SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE13 ( mSPL13 ), which has silent mutations complementary sequence, over-accumulated SPL13 mRNA exhibited a delay seedling development. Microarray...
Summary The micropylar region of endosperm in a seed, which is adjacent to the radicle tip, called ‘endosperm cap’, and specifically activated before emergence. This activation cap widespread phenomenon among species prerequisite for completion germination. To understand mechanisms cap‐specific gene expression tomato seeds, GeneChip analysis was performed. major groups cap‐enriched genes were pathogenesis‐, cell wall‐, hormone‐associated genes. promoter regions contained DNA motifs...
SWI/SNF chromatin remodelers are evolutionarily conserved multiprotein complexes that use the energy of ATP hydrolysis to change structure. A characteristic feature is occurrence in both catalytic ATPase subunit and some auxiliary subunits, bromodomains, protein motifs capable binding acetylated histones. Here, we report Arabidopsis bromodomain-containing proteins BRD1, BRD2, BRD13 likely true subunits interact with core components SWI3C SWP73B. Loss function each single BRD caused early...
Most plants encounter water stress at one or more different stages of their life cycle. The maintenance genetic stability is the integral component desiccation tolerance that defines storage ability and long-term survival seeds. Embryonic axes desiccation-sensitive recalcitrant seeds Acer pseudoplatnus L. were used to investigate genotoxic effect desiccation. Alkaline single-cell gel electrophoresis (comet assay) methodology was optimized provide unique insights into onset repair DNA strand...
Summary Methylated inositol, d ‐pinitol (3‐ O ‐methyl‐ ‐ chiro ‐inositol), is a common constituent in legumes. It synthesized from myo ‐inositol two reactions: the first reaction, catalyzed by ‐inositol‐ ‐methyltransferase ( IMT ), consists of transfer methyl group S ‐adenosylmethionine to with formation ‐ononitol, while second ‐ononitol epimerase OEP involves epimerization ‐pinitol. To identify genes involved biosynthesis model legume Medicago truncatula , we conducted BLAST search on its...
Part of the PSPAL1 gene (corresponding to proximal promoter, exon 1 and intron) from eight pea varieties was sequenced compared published sequence Midoriusui cultivar (GenBank: D10002.1). The sequences showed a very high level identity (96-99%), except in five there occurred motif TTATTACAAAATATTA close Goldberg-Hogness (TATA) box, it not detected other four varieties, including Midoriusui. Plants were subjected controlled infection with Mycosphaerella pinodes disease index determined (it...
