Description This study reports generation of large-scale genomic resources for pigeonpea, a so-called ‘orphan crop
species’ of the semi-arid tropic regions. FLX/454 sequencing carried out on a normalized cDNA pool prepared
from 31 tissues produced 494 353 short transcript reads (STRs). Cluster analysis of these STRs,
together with 10 817 Sanger ESTs, resulted in a pigeonpea trancriptome assembly (CcTA) comprising of
127 754 tentative unique sequences (TUSs). Functional analysis of these TUSs highlights several active
pathways and processes in the sampled tissues. Comparison of the CcTA with the soybean genome
showed similarity to 10 857 and 16 367 soybean gene models (depending on alignment methods).
Additionally, Illumina 1G sequencing was performed on Fusarium wilt (FW)- and sterility mosaic
disease (SMD)-challenged root tissues of 10 resistant and susceptible genotypes. More than 160
million sequence tags were used to identify FW- and SMD-responsive genes. Sequence analysis of CcTA
and the Illumina tags identified a large new set of markers for use in genetics and breeding, including
8137 simple sequence repeats, 12 141 single-nucleotide polymorphisms and 5845 intron-spanning
regions. Genomic resources developed in this study should be useful for basic and applied research, not
only for pigeonpea improvement but also for other related, agronomically important legumes.
