1. Molecular Mechanisms Underlying Microbial Disease Control in Intercropping

Author:
Zhu, Shusheng; Morel, Jean-Benoît

inoculum,   etc   ; disease control; induced resistance; intercropping; nutrients; pathogens; plant protection;     Show all 7 Subjects
Abstract:
... Many reports indicate that intercropping, which usually consists of growing two species next to each other, reduces the incidence of microbial diseases. Besides mechanisms operating at the field level, like inoculum dilution, there is recent evidence that plant-centered mechanisms with identified plant molecules and pathways are also involved. First, plants may trigger the induction of resistance ...

Abstract:
... Microbes influence plant phenotypes but most known examples of this are from the study of below-ground microbes and plant disease modification. To examine the potential importance of phyllosphere microbes on non-disease related plant traits, we used sterile Arabidopsis clones to test the effects of foliar fungi on flowering phenology and reproductive allocation under conditions of varying water st ...
