Identification and Expression Analysis of the Dof Gene Family in Eucalyptus grandis
摘要
Abstract
The Dof(DNA binding with one finger)family of transcription factors is a special kind found in plants and is crucial for biological processes including photomorphogenesis,stress response,and plant growth and development.This research focuses on the Eucalyptus grandis Dof gene family,systematically analyzing its evolutionary relationships,gene structure,cis-acting elements,member identification,and synteny analysis.According to the findings,26 members of the Dof gene family were found in the E.grandis genome.These members generally reside in the nucleus,with protein lengths ranging from 183 to 516 amino acids,and an isoelectric point that is often higher than 7.0.According to chromosomal location,all proteins have the characteristic Dof zinc finger domain,and the 26 EgrDof genes are widely dispersed over 10 chromosomes.According to an analysis of the cis-acting regions in the promoters,abiotic stress regulation,hormone response,and light sensing are all extensively impacted by genes.EgrDofs expression levels are higher in stems and phloem,while levels are comparatively low in leaves at various development stages.This study offers a strong basis for comprehending the regulatory networks and biological functions of Dof genes.关键词
