阳春砂果实发育过程中的表观性状变化与赤霉素相关基因的表达模式
Morphological changes and gibberellin-related gene expression patterns during fruit growth and development of Amomum villosum
摘要
Abstract
The fruit of Amomum villosum is highly valued for its medicinal and edible properties.However,the fruit abscission rate is exceptionally high,resulting in low unit yield.To better understand the fruit growth and development,this study investigated the characteristic changes of fruits and the expression patterns of GA-related genes in both fruits and fruit stalks.Results revealed that it takes approximately 90 days for the ovary of A.villosum to reach maturity.Fruit growth pattern exhibited a slow-fast-slow trend,with the peak of fruit weight accumulation occurring between the 14 and 25 days after artificial pollination(DAP).Before the 27 DAP,significant changes were observed in the ovary,fruit color,pericarp thickness,and fruit thorn length.Additionally,ten candidate GA-related genes,including 1 GA13ox,1 GA20ox,1 GA3ox,2 GA2oxs,4 GID1cs,and 1 DELLA,were analyzed using bioinformatics tools.The GA-related genes in fruit and fruit stalk exhibited significant correlations with fruit growth/development and fruit dropping.Overall,the fruit growth and development law,and the expression patterns of GA-related genes provided a theoretical foundation for further functional study and the screening of candidate genes for potential applications in A.villosum.关键词
