Genome-Wide Identification and Expression of the ERF Gene Family in Populus trichocarpa and Their Responses to Nitrogen and Abiotic Stresses

Life, Journal Year: 2025, Volume and Issue: 15(4), P. 550 - 550

Published: March 27, 2025

The ethylene response factor (ERF) family is a prominent plant-specific transcription family, which plays crucial role in modulating plant growth and stress tolerance. In this study, total of 210 ERFs were identified Populus trichocarpa, comprising 29 AP2 (APETALA2) subfamily members, 176 ERF 5 RAV (related to ABI3/VP1) members. duplication events the PtERF members exclusively occurred within subfamilies. A 168 pairs found among 161 genes, all them fragment duplications. Gene structure analysis revealed that most only had one exon without introns, six or more introns exons, lacked except for PtERF102. Considerable cis-acting elements associated with development, response, hormone light detected promoters genes. expression levels PtERFs highest roots across tissues winter seasons. Furthermore, nitrate urea stimulated co-expression network based on indicated their potential roles signaling, acyltransferase activity, chemicals. This study provides novel insights into investigating environmental poplar species.

Characterization of OfERF17 as a Key Regulator of Petal Senescence in Osmanthus fragrans

Forests, Journal Year: 2025, Volume and Issue: 16(4), P. 615 - 615

Published: March 31, 2025

Osmanthus fragrans is a highly valued ornamental tree species in China, but its short flowering period limits appeal. Investigating the mechanisms of flower senescence O. therefore significant importance. Ethylene, key endogenous hormone, plays central role senescence, and AP2/ERF gene family, which includes ethylene response factors, known to regulate this process various plants. Transcriptome sequencing expression analysis identified OfERF17 as critical influencing petal fragrans. Bioinformatics revealed that lacks transmembrane transport structures contains multiple phosphorylation sites shares close phylogenetic relationship with Olea europaea var. Sylvestris. Subcellular targeting yeast-based auto-activation tests resides nucleus possesses transcriptional self-activation capability. Transient studies conducted petals indicated decrease expressions two genes associated namely, OfSAG21 OfACO3, when compared control group. Additionally, levels hydrogen peroxide (H2O2) malondialdehyde (MDA) were markedly reduced. Transgenic Nicotiana tabacum blooms one day more than wild type, NtSAG12 NtACO1 lower type. These results suggest functions delay This study enhances our knowledge molecular underlying provides insights into strategies for prolonging period.
