Root-knot nematodes are a type of plant parasitic nematodes widely distributed around the world。They invade the roots of crops，Stimulates roots to form tumor-like structures - root knots，Resulting in crop yield reduction or even death。Currently，The mechanism of interaction between plants and root-knot nematodes is not fully understood。Recently，Wang Shaohui, bet365 online sports betting app College、Professor Zhao Wenchao’s team explained the mechanism of interaction between tomatoes and root-knot nematodes from two aspects: assimilate competition and hormone resistance regulation。
The team is herePlant Biotechnology JournalPublished a research paper titled "SlVQ15 recruits SlWRKY30IIc to link with jasmonatepathway in regulating tomato defense against bet365 online sports betting app"。This paper reveals that SlVQ15 recruits the transcription factor SlWRKY30IIc，Molecular mechanism of coupled jasmonate pathway regulating tomato response bet365 live casino reviewino blackjackto root-knot nematode invasion，Provide new ideas for resistance breeding of Solanaceae plants。
SlVQ15 without affecting the growth and development of tomatoes，Positive regulation of tomato resistance bet365 live casino reviewino blackjackto bet365 online sports betting app。By yeast two-hybrid experiment，The interacting protein SlWRKY30IIc of SlVQ15 was screened。SlWRKY30IIc and SlVQ15 cooperate to regulate tomato response to root-knot nematode invasion。Jasmonate signal transduction pathway inhibitor SlJAZs interacts with SlVQ15/SlWRKY30IIc，Thereby interfering with the interaction between SlVQ15 and SlWRKY30IIc。Vice versa，SlWRKY30IIc direct bindingSlJAZspromoter, repressionSlJAZs10641_10644，SlVQ15 promotes the function of SlWRKY30IIc，And SlJAZ5 antagonizes the function of SlWRKY30IIc，Thereby forming a feedback adjustment mechanism。In addition，SlWRKY30IIcits own expression is directly regulated by the transcription factor SlMYC2, which negatively regulates root-knot nematode resistance。

Plants resist nematode attack，A series of complex defense systems have evolved，bet365 online sports betting mobileSugar competition is one of the important defense strategies。Once nematodes invade the plant，The plant will consume a lot of sugar to support its life activities and reproduction needs。To weaken this offensive of nematodes，Plants will adjust cleverly，Reduce sugar reserves in roots，To curb the growth and development process of nematodes。Nevertheless，The molecular mechanism by which plants and nematodes compete with each other for assimilates is still unclear。
The team is hereJournal of Integrative Plant BiologyA research paper titled "The miR396a-SlGRF8 module regulates sugar accumulation in the roots via SlSTP10 during the interaction between bet365 online sports betting app and tomato plants" was published online (doi: http://doi.org/10.1111/jipb.13794）。This study deeply reveals the molecular mechanism of sugar competition in the interaction between tomatoes and bet365 online sports betting app，Laid the foundation for exploring the plant-nematode interaction mechanism。By regulating the miR396a-SlGRF8-SlSTP10 module，Can effectively regulate sugar distribution in tomato roots，Thus improving tomato resistance bet365 live casino reviewino blackjackto bet365 online sports betting app，Provide new ideas for nematode control。
The article proposes a potential regulatory model，Describes the interaction between tomato and root-knot nematode (RKN)，Sugar partitioning mechanism mediated by the miR396a–SlGRF8–SlSTP10 module。After root-knot nematode infects tomato roots，will reduce the expression of miR396a，and upregulated at the transcriptional levelSlGRF8andSlSTP10Gene expression，Reduce the soluble sugar content in roots，Thereby inhibiting the growth and development of bet365 online sports betting app，Improving tomato resistance bet365 live casino reviewino blackjackto bet365 online sports betting app。
