Rice advances! A study identifies Rsf1, a cysteine-rich protein linked to root-knot nematode resistance. Discoveries in rice accessions reveal TATA-box variations. Retweet to spread the word! PMID:42331810, Nat Commun 2026, @NatureComms https://doi.org/10.1038/s41467-026-74677-7 #Medsky #Pharmsky 🧪
A natural variation in rice susceptibility factor Rsf1 confers resistance to root-knot nematode | Nature Communications
Rice root-knot nematode (RRKN, Meloidogyne graminicola) is a destructive nematodes threatening global rice production. Few RRKN-resistant resources have been reported and their natural variations remain largely unknown. Here, we identify RRKN susceptibility factor 1 (Rsf1), encoding a cysteine-rich protein, via Genome-Wide Association Study (GWAS), multi-omics analysis, and functional validation. A natural variation in the TATA-box of OsRsf1 is observed, wherein RRKN-susceptible rice accessions contain haplotype (Hap) A while resistant accessions contain HapG. OsRsf1 with HapA is highly expressed and induced by RRKN infection, while HapG OsRsf1 shows low expression, conferring enhanced RRKN resistance. We further demonstrate that transcription factor Myb44 promotes OsRsf1 expression. Knockouts of OsRsf1 in rice and its ortholog AtRsf1 in Arabidopsis significantly enhanced nematode resistance, indicating that functional conservation. Mutations in OsRsf1 trigger a general defence respons

Root-knot nematodes pose a substantial threat to tomato production in high tunnels. Vijay Kunwar et al. found that Mi-1-virulent Meloidogyne incognita isolates from resistant tomato rootstocks fail to reproduce on susceptible and resistant peppers: https://doi.org/10.1094/PDIS-09-25-1948-SC
Fig. 3. Response of pepper cultivars ‘Baron’ (without N gene) and ‘Charleston Belle’ (carrying N gene) to RKN-14a and RKN-14v isolates. Four-week-old plants were inoculated with 500 J2s and examined at 10 dpi. Each root tip was imaged before (A, C, E, and G) and after (B, D, F, and H) dissection to show penetrating juveniles (red arrows). A and B, RKN-14a on ‘Baron’. C and D, RKN-14a on ‘Charleston Belle’. E and F and G and H, RKN-14v on ‘Baron’ and ‘Charleston Belle’, respectively. Scale bar = 0.45 mm.
