Quantitative Trait Locus Analysis of Microscopic Phenotypic Characteristic Data Obtained Using Optical Coherence Tomography Imaging of Rice Bacterial Leaf Blight Infection in the Field

Rapid climate change has increased the incidence of various pests and diseases, these threaten global food security. In particular, BLB (bacterial leaf blight) is caused by Xoo (Xanthomonas oryzae pv. oryzae) its main characteristic that rice suddenly dries withers. Recently, omics have been effectively used in agriculture. it a key technology can accurately diagnose diseases field. Until now, QTL (quantitative trait loci) mapping analyzed using only subjective phenotypic data experts. However, this study, were diagnosed OCT (optical coherence tomography), was performed thickness angles after inoculation. After inoculation 120 Cheongcheong/Nagdong double haploid (CNDH) population, changing angle, OsWRKY34q1 detected RM811-RM14323 chromosome 1. always had higher expression level BLB-resistant population than susceptible belongs to WRKY family genes. could be develop varieties response current era unpredictable change.
