Root Transcriptome and Metabolome Profiling Reveal Key Phytohormone-Related Genes and Pathways Involved Clubroot Resistance in Brassica rapa L.

Xiaochun Wei et al.

Summary: This study investigated the transcriptome and metabolome changes in Brassica crops infected with Plasmodiophora brassicae, highlighting the role of plant hormones in defense mechanisms and resistance to clubroot disease. The findings suggest a general model of hormone-mediated defense mechanism in plants and pave the way for enhancing clubroot resistance in Brassica rapa.

De novo transcriptome assembly, polymorphic SSR markers development and population genetics analyses for southern corn rust (Puccinia polysora)

Qiuyu Sun et al.

Summary: In this study, high-quality cDNA sequence reads of Southern corn rust disease were obtained using Illumina sequencing technology, resulting in the identification of a large number of potential SSRs. Nine polymorphic SSR markers were developed to evaluate the genetic diversity and population structure of 96 isolates from Guangdong Province in China, showing dominant clonal reproduction of P. polysora. The results provide valuable information for molecular genetic analysis of P. polysora and related species.

Transcriptome and Coexpression Network Analyses Reveal Hub Genes in Chinese Cabbage (Brassica rapa L. ssp. pekinensis) During Different Stages of Plasmodiophora brassicae Infection

Yuxiang Yuan et al.

Summary: Clubroot, caused by Plasmodiophora brassicae, is one of the most destructive diseases of Chinese cabbage worldwide, but the resistance mechanisms are still unclear. This study identified genes associated with clubroot resistance, including those related to auxin, PR, oxidative stress, and transcription factors. The results provide valuable information for better understanding the molecular regulatory mechanism of Chinese cabbage clubroot resistance.

Genetic diversity and population structure analysis of 161 broccoli cultivars based on SNP markers

Jingjing Huang et al.

Summary: This study analyzed the genetic diversity and population structure of 161 broccoli cultivars in China, revealing similarities in genetic backgrounds between foreign and domestic cultivars, but differences between domestic cultivars and Japanese cultivars. Population structure analysis showed that the 161 cultivars could be simplified into 1 simple group and 1 mixed group.
