Abstract
Severe outbreaks of Phytophthora fruit rot on brinjal, ridge gourd, and tomato have been observed since 2011 in Andhra Pradesh, Karnataka,
Telangana, and Tamil Nadu states of India. Therefore, 76 Phytophthora nicotianae isolates, recovered from brinjal (17), ridge gourd (40), and
tomato (19) from different localities in these states during the June to December cropping season of 2012 and 2013, were characterized based on
phenotypic and genotypic analyses and aggressiveness on brinjal, tomato, and ridge gourd. All brinjal and ridge gourd isolates were A2, while tomato
isolates were both A1 (13) and A2 (6). All isolates were metalaxyl sensitive. In addition, isolates were genotyped for three mitochondrial (ribosomal
protein L5-small subunit ribosomal RNA [rpl5-rns], small subunit ribosomal RNA-cytochrome c oxidase subunit 2 [rns-cox2], and cox2+spacer) and three
nuclear loci (hypothetical protein [hyp], scp-like extracellular protein [scp], and beta-tubulin [b-tub]). All regions were polymorphic but nuclear regions were more variable than mitochondrial regions. The network analysis of genotypes using the combined dataset of three nuclear regions revealed a
host-specific association. However, the network generated using mitochondrial regions limited such host-specific groupings only to brinjal isolates.
P. nicotianae isolates were highly aggressive and produced significantly (P<0.01) larger lesions on their respective host of origin than on other hosts. The results indicate significant genetic variation in the population of P. nicotianae, leading to identification of host-specific lineages responsible for severe outbreaks on brinjal, ridge gourd, and tomato.
