Fig. 3From: Genome-wide identification and expression profiling of invertase gene family for abiotic stresses tolerance in Poncirus trifoliataChromosomal map of PtrINV genes within the genome of P. trifoliata. Thirteen PtrINV genes were mapped onto eight of nine P. trifoliata chromosomes (2n = 18). Chromosome numbers indicated below each chromosome. PtrA/NINV genes are shown in green, PtrVINV genes are in blue, and PtrCWINV genes are in red. Genome-wide or segmentally duplicated genes are linked by blue lines. Tandemly duplicated genes are linked with green lines. Scale bar is 500 k bases (kb)Back to article page
