Recent work including high-resolution genome-wide analysis uncovered a new trimeric complex involved in transcription elongation, both as an integral part of the NuA4 histone acetyltransferase and as an independent functional entity. The complex is conserved in eukaryotes and is named TINTIN, for Trimer Independent of NuA4 for transcription Interactions with Nucleosomes. This point of view covers the current knowledge regarding TINTIN's function in modulating chromatin structure and influencing transcription elongation in eukaryotes. It also points to several physical and functional links to co-transcriptional processes, including interactions with the mRNA splicing machinery and the nuclear exosome.

In our study, we aimed to identify new mutants resulting from ONSEN transposition in Arabidopsis thaliana by subjecting nrpd1 mutants to heat stress. We isolated a mutant with a significantly elongated hypocotyl, named "Long hypocotyl in ONSEN inserted line 1" (HYO1). This phenotype was heritable, with progeny consistently displaying longer hypocotyls than the wild type.

Maize lethal necrosis (MLN) is a significant threat to food security in Sub-Saharan Africa (SSA), with limited commercial inbred lines displaying tolerance. This study analyzed the transcriptomes of four commercially used maize inbred lines and a non-adapted inbred line, all with varying response levels to MLN. RNA-Seq revealed differentially expressed genes in response to infection by maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV), the causative agents of MLN.

Plants respond to higher ambient temperatures by modifying their growth rate and habitus. This review aims to summarize the accumulated knowledge obtained with Arabidopsis seedlings grown at normal and elevated ambient temperatures. Thermomorphogenesis in the shoot and the root is overviewed separately, since the experiments indicate differences in key aspects of thermomorphogenesis in the two organs.

Xinjiang Production & State Key Laboratory Incubation Base for Conservation and Utilization of Bio-Resource in Tarim Basin, Alar 843300, China.

The transcription factors in the ABA Response Element Binding (AREB) protein family were differentially regulated under multiple stress conditions; however, functional analyses of AREB in Oliv. had not been conducted previously. In the present study, the comprehensive identification of the gene family and the function of in response to drought stress in were elucidated.

Background: Eukaryotic RNA polymerase I consists of 12 or 11 core subunits and three dissociable subunits, Rrn3, A34, and A49. The A34 and A49 subunits exist as a heterodimer. In silico analysis of the A34 family of transcription factors demonstrates a commonly shared domain structure despite a lack of sequence conservation, as well as N-terminal and C-terminal disordered regions.
