薄壳山核桃MADS基因家族的全基因组鉴定及生物信息学分析
Genome-wide identification and bioinformatics analysis of the MADS gene family in Carya illinoinensis(Wangenh.)K.Koch
摘要
Abstract
The MADS genes are a class of important transcriptional regulatory factors,with extensive biological func-tions.They are involved in the growth,development,and signal transduction of multiple species,and their biological char-acteristics have been identified in various organisms.In this study,bioinformatics methods were employed to identify and analyze the MADS gene family members in Carya illinoinensis(Wangenh.)K.Koch.A total of 81 MADS gene family mem-bers were identified,which were unevenly distributed across 16 chromosomes.Based on the results of phylogenetic tree analysis,the MADS proteins were divided into type-Ⅰ(20)and type-Ⅱ(61).The genes of this family in Carya illinoinensis were found to contain a large number of cis-acting elements,including plant hormone response ele-ments,stress response elements,and light response ele-ments.The study revealed that these cis-acting elements were widely distributed in the promoter regions of the MADS genes,indicating that the MADS genes had played an important role in the adaptation to environmental changes and the growth and development of Cary a illinoinensis.The expression levels of different MADS family genes in Carya illinoinen-sis varied greatly in different tissues and at different times.For example,CiMADS46 had a high expression level in the stem,CiMADS7 had a high expression level in the fruit,and the expression level of CiMADS11 decreased over time.The MADS genes were found to exhibit distinct tissue-specific expression patterns.It was speculated that the MADS gene family might play important roles in the processes of flower formation and fruit development,and they might have a certain degree of functional diversity at different developmental stages.The results of this study lay the foundation for further research on the functions and characteristics of CiMADS genes and provide a reference for the identification and characterization of MADS gene family members in other species.关键词
