Spatial Analysis of Phytophthora infestans Genotypes and Late Blight Severity on Tomato and Potato in the Del Fuerte Valley Using Geostatistics and Geographic Information Systems.

abstract：:The rice blast resistance gene Pid3 encodes a nucleotide-binding-site leucine-rich repeat (NBS-LRR) protein. This gene was cloned from the rice 'Digu' (indica) by performing a genome-wide comparison of the NBS-LRR gene family between two genome-sequenced varieties, '9311' (indica) and 'Nipponbare' (japonica). In this ...
