From: Sequencing and analysis of the gene-rich space of cowpea
Mapping of cowpea assemblies and singletons to the M. truncatula pseudomolecules. GSR assemblies and singltons were mapped by tblastx searches to the M. truncatula chromosome-scale pseudomolecules available on the TIGR M. truncatula database. The broad green lines represent tblastx alignments; narrow lines connect High-scoring Segment Pairs (HSPs) derived from the same cowpea sequence. An HSP consists of two sequence fragments of arbitrary but equal length whose alignment is locally maximal and for which the alignment score meets or exceeds a threshold or cutoff score. A: An example of mapping cowpea contigs and singletons to a 40 kb region of chromosome 0 (which represents BACs that have not been anchored to the genetic map). B: A closer view of the same region from 396 k to 404 k. C: A region of M. truncatula chromosome 6 where a single cowpea GSR spans and has high quality tblastx matches to three distinct IMGAG gene models, indicating microsynteny. M. truncatula gene model AC134521_19 has no match in that region of the cowpea genome. D: A region of M. truncatula chromosome 2 where there are several GSR matches, but no M. truncatula gene model.
