Description Accepted date: 06 August 2020
Fusarium wilt (FW) disease is the key constraint to grain legume production worldwide.
The projected climate change is likely to exacerbate the current scenario. Of the various
plant protection measures, genetic improvement of the disease resistance of crop
cultivars remains the most economic, straightforward and environmental-friendly option
to mitigate the risk. We begin with a brief recap of the classical genetic efforts that
provided first insights into the genetic determinants controlling plant response to different
races of FW pathogen in grain legumes. Subsequent technological breakthroughs
like sequencing technologies have enhanced our understanding of the genetic basis
of both plant resistance and pathogenicity. We present noteworthy examples of
targeted improvement of plant resistance using genomics-assisted approaches. In
parallel, modern functional genomic tools like RNA-seq are playing a greater role in
illuminating the various aspects of plant-pathogen interaction. Further, proteomics and
metabolomics have also been leveraged in recent years to reveal molecular players
and various signaling pathways and complex networks participating in host-pathogen
interaction. Finally, we present a perspective on the challenges and limitations of highthroughput phenotyping and emerging breeding approaches to expeditiously develop
FW-resistant cultivars under the changing climate.
