Genome-Wide Identification and Functions against Tomato Spotted Wilt Tospovirus of PR-10 in .

Tomato spotted wilt virus impacts negatively on a wide range of economically important plants, especially tomatoes. When plants facing any pathogen attack or infection, increase the transcription level of plant genes that are produced pathogenesis-related (PR) proteins. The aim of this study is a genome-wide identification of PR-10 superfamily and comparative analysis of and gene functions against tomato responses to biotic stress (TSWV) to systemic resistance in tomato. Forty-five candidate genes were identified, with a length of 64-210 amino acid residues and a molecular weight of 7.6-24.4 kDa. The gene was found on ten of the twelve chromosomes, and it was determined through a genetic ontology that they were involved in six biological processes and molecular activities, and nine cellular components. Analysis of the transcription level of PR-10 family members showed that the gene (Solyc09g090980) has high expression levels in some parts of the tomato plant. and gene transcription and activity in tomato leaves were strongly induced by TSWV infection, whereas H8 plants having the highest significantly upregulated expression of and gene after the inoculation of TSWV, and TSWV inoculated in M82 plants showed significantly upregulated expression of gene comparatively lower than H8 plants. There was no significant expression of gene of TSWV inoculated in M82 plants and then showed highly significant correlations between and genes at different time points in H8 plants showed significant correlations compared to M82 plants after the inoculation of TSWV; a heat map showed that these two genes may also participate in regulating the defense response after the inoculation of TSWV in tomato.
