SPL (SQUAMOSA promoter binding protein-like), as one family of plant transcription factors, plays an important function in growth and development response to environmental stresses. Despite gene families having been identified various species, the understanding this peanuts remains insufficient. In study, thirty-eight genes (AhSPL1-AhSPL38) were classified into seven groups based on a phylogenetic analysis. addition, thorough analysis indicated that AhSPL experienced segmental duplications. The structure protein motif patterns revealed similarities exons introns, well organization motifs within same group, thereby providing additional support conclusions drawn from regulatory elements RNA-seq data suggested might be widely involved peanut development, Furthermore, expression some genes, including AhSPL5, AhSPL16, AhSPL25, AhSPL36, induced by drought salt Notably, potentially regulated factors with distinct functionalities, such ERF, WRKY, MYB, Dof, microRNAs, like ahy-miR156. overexpression AhSPL5 can enhance tolerance transgenic Arabidopsis enhancing its ROS-scavenging capability positively regulating stress-responsive genes.

Cbuhdz34, a Homeodomain Leucine Zipper Transcription Factor, Positively Regulates Tension Wood Formation and Xylem Fibre Cell Elongation in Catalpa bungei

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

Catalpa bungei is a highly valued timber species renowned for its superior wood properties. However, the development of tension (TW) induced by wind and other mechanical stresses during growing season significantly reduces economic value. Although Homeodomain Leucine Zipper (HD-Zip), plant-specific transcription factor family, has been reported to play various roles in plant growth, development, stress resistance, systematic characterisation HD-Zip gene family C. bungei, particularly regarding regulatory mechanisms involved TW formation, still lacking. Here, we identified total 48 genes (Cbuhdzs) analysed their phylogeny, structure, expression profiles. In particular, Cbuhdz34, member I subfamily, was specifically upregulated formation. To further explore function, overexpressed Cbuhdz34 (OE-Cbuhdz34) poplar '84 K', which led noticeable changes growth fibre cell length. Moreover, compared with wild-type plants, OE-Cbuhdz34 plants presented increased formation under bending stress, as indicated width, gelatinous layer eccentric rate, suggesting positive role Additionally, hierarchical genetic network analysis revealed direct targets including CbuMYB63 three wall synthesis (CbuGATL1, CbuFLA17, CbuLRR14). Further, yeast one-hybrid dual-luciferase reporter assays confirmed activation these Cbuhdz34. conclusion, our results provide insights into molecular regulates lay foundation potential improvement quality bungei.

Genome-wide characterization of AhBAG genes in peanut reveals their role in bacterial wilt resistance and hormone response

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Background The BAG gene family, encoding Bcl-2-associated anti-apoptotic proteins, plays pivotal roles in regulating plant growth, development, and stress responses. Peanut (Arachis hypogaea L.), a globally significant oilseed cash crop, is highly valued for its economic importance. However, systematic genome-wide analysis functional characterization of the family peanut remain largely unexplored. Results In this study, we identified 13 AhBAG genes genome, which are unevenly distributed across 11 chromosomes. Phylogenetic revealed that these AhBAGgenes, together with members from other species, classified into four distinct clades, underscoring their evolutionary conservation. Segmental duplication was as major driver expansion family. Notably, AhYSVF0U exhibited upregulation under Ralstonia solanacearum infection abscisic acid treatment, suggesting potential involvement mediating resistance to bacterial wilt. Conclusions This study provides comprehensive insights characteristics offers valuable genetic resources molecular breeding programs aimed at improving tolerance peanut.

Tropical wetlands are some of the most threatened ecosystems in world. Pterocarpus officinalis exists swampy riparian and fresh-water coastal areas across neotropics, supporting biodiversity storm surge flooding protection as well water filtration. In Puerto Rico, P. officinalis-dominated forests have been severely declining recent decades, mainly due to land development. Reversing this trend face climate change projected sea level rise via ecological restoration may benefit from understanding phenotypic traits suitable for future climates. Currently, there no seed sourcing guidelines restoration, understudied nature species.
