Effects of different soil conditions on the flower color polymorphism of Primula pamirica and transcriptomic analysis
摘要
Abstract
Flower color,as a key phenotypic characteristic exhibited by angiosperms in their adaptation to the ecological environment,is the result of the synergistic interaction between genetic regulatory networks and environmental factors.Current research primarily focuses on the maintenance mechanisms,driving factors,and molecular regulatory networks of flower color.However,there is still a lack of systematic studies on the interaction mechanisms between soil environmental factors and molecular regulatory networks.This study utilized Primula pamirica,a distylous plant producing flowers in four flower-color morphs(white,light white,light purple,and purple),as the experimental material.A comprehensive comparative analysis was conducted based on the corolla color parameters,soil water contents and mineral element contents of the plant roots,and transcriptomic profiling data across the four flower-color morphs,and preliminary screened to identify candidate transcription factors involved in the formation of flower color polymorphism.The results were as follows:(1)Plants with white and light white corollas predominantly occured in soil environments characterized by high water content and low mineral element content,whereas those with purple and light purple corollas were frequently distributed in soils with low water content and high mineral element content.(2)Pathways such as the phenylalanine metabolism,carotenoid biosynthesis,metal ion transport,and amino acid transport played critical roles in floral pigmentation regulation.(3)Related members of the MYB,bHLH,ZIP,and WRKY gene families were identified as key candidate genes of floral formation,with related members of ZIP and WRKY gene families showing significant regulatory effects on purple corolla formation.In conclusion,the flower color polymorphism in P.pamirica is the result of the genetic regulatory networks and soil environmental factors(soil water status and mineral elements).关键词
