Rumi Sasai, Hiroaki Tabuchi, Kenta Shirasawa, Kazuki Kishimoto, Shusei Sato, Yoshihiro Okada, Akihide Kuramoto, Akira Kobayashi, Sachiko Isobe, Makoto Tahara, Yuki Monden, Development of molecular markers associated with resistance to Meloidogyne incognita by performing quantitative trait locus analysis and genome-wide association study in sweetpotato, DNA Research, Volume 26, Issue 5, October 2019, Pages 399–409, https://doi.org/10.1093/dnares/dsz018. They performed double-digest restriction site-associated DNA sequencing (ddRAD-seq) analysis in an S1 mapping population derived from the self-pollination of sweetpotato cultivar Xushu18, which produced 28,087 SNP markers mapped onto 96 linkage groups (LGs) covering a total distance of 33,020.4 cM. The sweetpotato individuals were shaded with newspapers during these treatments because they did not have sufficient roots to be exposed to direct sunlight. A sum of 7,669 ESTs was obtained after trimming. We divided the plants into eight groups (=23) based on the presence or absence of the combinations of these detected QTLs.

Meloidogyne larvae invade the roots and feed in the vascular system of the crop, causing formation of giant cells. It typically incites large, usually irregular galls on roots as a result of parasitism. Among the 1,215 IES markers generated, 978 (80.5%) were trinucleotide repeats, whereas 133 (10.9%) and 104 (8.6%) were di- and tetranucleotide repeats, respectively. The mean number of egg masses for the three races of the nematode Meloidogyne incognita on F1 plants from a cross between the resistant cultivar J-Red and the susceptible cultivar Choshu in sweetpotato grouped by the Itr_sc002268_68403 marker genotype. Kuranouchi T., Momota U., Takada A., et al. Yamakawa O., Yoshinaka M., Kumagai T., et al. We are currently working on QTL analysis and the development of markers for the selection of resistance to other races of nematodes. Some of the most damaging species like Meloidogyne. Recently, Tabuchi et al.18 have reported that SP6 could be classified into two races (SP6-1 and SP6-2) and SP6-1 was identified in Chiba. Chang K.Y., Lo H.F., Lai Y.C., Yao P.J., Lin K.H., Hwang S.Y. Using cryo-TOF-SIMS/SEM, cadaverine was indeed detected in soybean root cortex cells and the surrounding rhizosphere, establishing a chemical gradient.
