The evolution of 5S rRNA gene unit (5S gene unit) was studied among the ten species belonging to Vigna subgenus Ceratotropis by sequencing and analyzing the intra- and inter-specific sequence heterogeneity. The 5S unit from these species ranged from 214 to 342 bp in length as a result of several indels in the intergenic spacer (IGS) region. A large deletion (>100 bp) was found specifically in the IGS of V. radiata accessions. IGS showed high sequence variation with more than 50% polymorphic and… CONTINUE READING
