identification and expression analysis of oleosin gene family in juglans regia l.

Oleosins as structural proteins play a crucial role in stabilization the oil-bodies, their size, number, and content. here, exon/intron structure, conserved motifs/ domains, and expression patterns of oleosin gene family were identified in diploid crop juglans regia l. this study found seven non-repetitive jroleosin genes through a genome-wide analysis, displaying remarkable structural and physicochemical differences. our phylogenetic analysis of the 46 oleosin genes revealed that how these genes are related, highlighting that they share conservations while also having unique divergences across different species. the jroleosin intronless genes (igs) might be examples of how evolution adapts to enhance the accuracy and effectiveness of gene expression. transcriptome analysis showed that the jroleosin genes were spatially and temporarily regulated with the highest transcript found in seeds and fruits. this suggests they are vital for storing lipids during these developmental stages. these results help us to better understand the features of the jroleosins gene family, especially their structure and expression. future research should concentrate on revealing how oleosin expression is controlled and how these proteins interact with others linked to lipid synthesis during seed development.
