Transcriptome and co-expression network analysis reveal the genetic basis of cell wall components in maize stalks.

BMC Genomics

July 2025

State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Maize Research Institute, Sichuan Agricultural University, Chengdu, 611130, China.

Unlabelled: Cellulose (CEL), hemicellulose (HCE), and lignin (LIG) are crucial constituents of the cell wall in maize stalks, significantly influencing stalk resistance to lodging and external stresses. The proportion of these contents also determines the application of maize stalks in animal feed, energy production, and other fields. Herein, two maize inbred lines with contrasting cell wall component contents in the stalk, MO190 (high CEL, HCE, and LIG contents) and MO194 (low CEL, HCE, and LIG contents), were subjected to analysis of transcriptomes at the seedling, jointing, silking, and grain stages.

The interaction between abasic (apurinic/apyrimidinic, AP) sites and aberrant uracil DNA glycosylase (UDG) contributes to cancer progression, establishing AP site recognition and UDG detection as critical tools for bioanalytical applications and clinical diagnostics. However, existing methods face challenges in achieving high sensitivity and specificity. In this work, we developed DNA-R5, a novel DNA adduct formed by conjugating AP sites with polyarginine-5 (R5), which generates distinctive current signatures in nanopore sensing.

Key Laboratory of Bio-Resource and Eco-Environment of Ministry of Education, College of Life Sciences, State Key Laboratory of Hydraulics and Mountain River Engineering, Sichuan University, Chengdu 610065, China. Electronic address:

Drought severely limits the growth and development of perennial trees, which activate the abscisic acid (ABA) signaling pathway to cope with this condition. Despite its importance, the transcriptional regulatory mechanisms associated with ABA in poplars remain poorly understood. In this study, we identified HIPP26-like (HIPP26L), a heavy-metal-associated isoprenylated plant protein gene in poplar, which localizes to the cytomembrane, cytoplasm, and nucleus under normal conditions but accumulates in the nucleus in response to ABA and mannitol treatment.

Evolutionary Genomics Unravels the Responses and Adaptation to Climate Change in a Key Alpine Forest Tree Species.

Mol Biol Evol

July 2025

Key Laboratory of Bio-Resource and Eco-Environment of Ministry of Education, College of Life Sciences, Sichuan University, Chengdu, Sichuan, China.

Despite widespread biodiversity loss, our understanding of how species and populations will respond to accelerated climate change remains limited. In this study, we integrate population genomics, experimental evolution, and environmental modeling to elucidate the evolutionary responses to climate change in Populus lasiocarpa, a key alpine forest tree species primarily distributed in the mountainous regions of a global biodiversity hotspot. Over historical timescales, our findings demonstrate that demographic dynamics, divergent selection, and long-term balancing selection have shaped and maintained genetic variation within and between populations.

In the present work, the reaction mechanism and kinetics of 2,2',4,4',5,6'-hexabrominated diphenyl ether (BDE-154) with OH were researched by employing density functional theory (DFT) and transition state theory (TST). The gas-phase and aqueous solution reaction mechanisms and kinetic parameters were computed at the level of M06-2X/6-311++G (3df, 3pd)//M06-2X/6-311G (d,p). The OH-addition of the non-bromine replaced carbon atom of the aromatic ring in BDE-154 is superior to substitution and H-abstraction mechanisms.
