Description
Katharina Sielemann and co-authors pinpoint the genes that let sugar beet tolerate a worm pest, in a 2023 study. Beet cyst nematodes cause serious yield loss. Warming climates favor the pest. Tolerant varieties that still yield well are a breeding priority. The team crossed tolerant and susceptible lines. They sequenced pooled offspring sorted by response. One genome region stood out as carrying the tolerance.
New markers narrowed the region further. Long-read assemblies of both parents gave full sequence context. Gene activity after infection was compared between the lines. A cluster of candidate genes resembled a known plant regulator gene. The candidates were active and differed between the lines. The authors present the locus as a breeding tool. Markers can now speed selection for tolerance. The work also opens study of how the genes act. Field testing of the candidates comes next.
