The Mechanism of Interaction Between Tomato and Botrytis cinerea to Regulate Plant Resistance Under the Combining of Temperature and Humidity in Green

Botrytis cinerea is a serious destructive fungal disease, which leads to tomato rot and yield reduction, and brings great economic losses to agricultural production. Temperature and humidity are two important environmental factors affecting plant pathogen interaction. However, the detailed combined mechanisms of temperature and humidity influencing this interaction remain unclear.

Recently, Horticulture Research published a research paper entitled “Combined effects of temperature and humidity on the interaction between tomato and Botrytis cinerea revealed by integration of histological characteristics and transcriptome sequencing” by Professor Li Jianming of Northwest University of Agriculture and Forestry Science and Technology (Advance Access), which revealed the interaction mechanism of greenhouse temperature and humidity combining on tomato and Botrytis cinerea.
In this study, the interaction between tomato and Botrytis cinerea in various temperature and humidity conditions was analyzed by histological observation and dual RNA-seq approach. The results showed that low humidity was not favorable for mycelial growth, resulting in infection failure. Both high and low temperatures at high humidity successfully inhibited pathogenic infection and disease incidence in the tomato plants, thus enhancing its resistance to B. cinerea

The results of this study explored a new way to control tomato gray mold through regulating greenhouse environment.
