Transcription profile of soybean-root-knot nematode interaction reveals a key role of phythormones in the resistance reaction

摘要: Root-knot nematodes (RKN– Meloidogyne genus) present extensive challenges to soybean crop. The line (PI 595099) is known be resistant against specific strains and races of nematode species, thus its differential gene expression analysis can lead a comprehensive profiling in the incompatible soybean-RKN interaction. Even though many disease resistance genes have been studied, little has reported about phytohormone crosstalk on modulation ROS signaling during Using 454 technology explore common aspects reaction both parasitism phases it was verified that hormone, carbohydrate metabolism stress related were consistently expressed at high levels infected roots as compared mock control. Most noteworthy include those encoding glycosyltransferases, peroxidases, auxin-responsive proteins gibberellin-regulated genes. Our data suggests key role auxins components gibberellin signal transduction, biosynthesis deactivation pathways their participation jasmonate redox homeostasis mediating plant growth responses biotic stress. Based this study we suggest reasonable model regarding complex mechanisms between hormones, mainly gibberellins auxins, which crucial modulate invasion. also includes recent findings concerning DELLA-like controlling immune or responses. Furthermore, provides dataset potential candidate involved resistance, tested further for biological process using functional genomics approaches.
