摘要

Plant growth and development are largely regulated by non-coding RNAs (ncRNA); thus ncRNA based markers would be rewarding in molecular breeding. In the present study, for the first time we developed total 623 ncRNA based SSRs including 119 microRNASSRs (miRNASSRs) and 504 long non-coding RNASSRs (lncRNASSRs) distributed across 12 Capsicum chromosomes. Out of 623 ncRNASSRs, 120 (including 60 each miRNASSRs and lncRNASSRs) were used for genotyping of 96 Capsicum accessions belonging to C. annuum, C. chinense and C. frutescens; and 75% SSRs were polymorphic. Model-based and distance-based cluster analyses identified three species specific clusters, i.e. cluster-I (C. annuum), cluster-II (C. frutescens) and cluster-III (C. chinense); therefore, these SSRs may have a potential role to play in interspecific Capsicum breeding. Tissue specific expression of SSR containing ncRNAs and versatile functions of their targets suggested the usefulness of SSRs for mapping of genes/QTLs and breeding of wide range of traits in Capsicum.

Annuum,C.Chinense和C. Frutescens的96个辣椒癌的基因分型; 75%的SSR是多态。基于模型的基于距离的聚类分析确定了三种特定簇,即Cluster-I(C. Annum),Cluster-II(C. Frutescens)和Cluster-III(C.Chinense);因此,这些SSRS可能在三种胶囊繁殖中发挥潜在的作用。 SSR的组织特异性表达含有NCRNA和其靶向的通用功能表明SSRS用于测定基因/ QTL和辣椒的各种性状的繁殖的有用性。
