The rapid spread of clubroot disease, which is caused by , threatens Brassicaceae crop production worldwide. Breeding plants that have broad-spectrum disease resistance is one of the best ways to prevent clubroot. In the present study, eight Chinese cabbage germplasms were screened using published clubroot-resistant (CR) loci-/gene-linked markers. A CR gene Crr3 potential carrier "85-74" was detected which linked to marker BRSTS61; however, "85-74" shows different responses to local pathogens "LAB-19," "LNND-2," and "LAB-10" from "CR-73" which harbors Crr3. We used a next-generation sequencing-based bulked segregant analysis approach combined with genetic mapping to detect CR genes in an F segregant population generated from a cross between the Chinese cabbage inbred lines "85-74" (CR) and "BJN3-1" (clubroot susceptible). The "85-74" line showed resistance to a local pathogen "LAB-19" which was identified as race 4; a genetic analysis revealed that the resistance was conferred by a single dominant gene. The CR gene which we named was mapped to a 60 kb (1 cM) region between markers yau389 and yau376 on chromosome A03. is located upstream of which was confirmed based on the physical positions of linked markers. The identification of linked markers can be applied to marker-assisted selection in the breeding of new CR cultivars of Chinese cabbage and other crops.

Background: Chinese cabbage is a cross-pollinated crop with remarkable heterosis, and male-sterile line is an important mean to produce its hybrids. In this study, a male-sterile mutant msm7 was isolated from a Chinese cabbage DH line 'FT' by using EMS-mutagenesis.
Results: Compared with the wild-type 'FT', the anthers of mutant msm7 were completely aborted, accompanied by the defects in leaf and petal development.

Leaf senescence is a major concern for postharvest leafy vegetables, as leaves are highly prone to yellowing and nutrient loss, resulting in reduced commercial value and limited shelf-life. This study aimed to investigate the effect of L-cysteine (L-cys) on postharvest Chinese flowering cabbage stored at 20 °C. The results showed that 0.

As the antibiotic resistance of pathogens becomes increasingly severe, it is becoming more feasible to use methods that suppress the virulence of pathogens rather than exerting selective pressure on their growth. , a dangerous opportunistic pathogen, infects hosts by producing multiple virulence factors, which are regulated by quorum-sensing (QS) systems, including the systems, systems, and systems. This study used the chromosome transcription fusion reporter model to screen the traditional Chinese medicine monomer library and found that bakuchiol can effectively inhibit the system and related virulence phenotypes of , including the production of virulence factors (pyocyanin, hydrogen cyanide, elastase, and lectin) and motility (swarming, swimming, and twitching motility) without affecting its growth.
