Genome-wide identification of the class III POD gene family and their expression profiling in grapevine (Vitis vinifera L)

Table. 1 The POD genes in grapevine with outlier Ka/Ks and various types of duplications of the POD gene pairs with the detection by the MCScan algorithm (i.e., Dispersed, proximal, tandem, and segmental)
