摘 要：Pathogenesis-related（PR） proteins play a crucial role in plant responses to pathogen infection and environmental ***-5 proteinis a thaumatin-like protein（TLP） that can improve plant resistance to *** this study,a TLP protein named PR-NP24 was identified as a member of the PR-5 *** expression of PR-NP24 in tomato fruits showed tissue-specific and was significantly abundant in the fruit *** analysis of PR-NP24 or TLPs was performed to investigate potential allergenic agents in fruits in certain Solanaceae *** better understand the regulation in tomato responses to abiotic and biotic stresses,the differential expression patterns of the PR-NP24 protein in the exocarp were investigated under different environmental conditions（e.g.,NaCl treatments,wound types and storage periods）.Relative expression of PR-NP24 was analyzed after the fruits were inoculated with Sclerotinia sclerotiorum and Botrytis cinerea,which was further validated by virus induced gene silencing（VIGS） ***,resistance of tomato fruits to pathogen infection was elevated by inducing the expression of PR-NP24 with the salt *** study provided new insights on postharvest resistance of tomato fruits regulated by *** molecular mechanism of such regulation is yet to be elucidated by the functional analysis in future.
