“…Several B. oleracea germplasm collections consisting of different morphotypes have been evaluated for clubroot resistance by various research groups, and several resistance sources have been identified. Fewer resistance accessions have been reported in cauliflower [ 51 , 52 , 53 , 54 ] compared to other B. oleracea varieties such as cabbage, kale, broccoli, brussels sprout, etc. [ 51 , 52 , 55 , 56 , 57 , 58 , 59 ].…”

Brassica oleracea is an agronomically important species of the Brassicaceae family, including several nutrient-rich vegetables grown and consumed across the continents. But its sustainability is heavily constrained by a range of destructive pathogens, among which, clubroot disease, caused by a biotrophic protist Plasmodiophora brassicae, has caused significant yield and economic losses worldwide, thereby threatening global food security. To counter the pathogen attack, it demands a better understanding of the complex phenomenon of Brassica-P. brassicae pathosystem at the physiological, biochemical, molecular, and cellular levels. In recent years, multiple omics technologies with high-throughput techniques have emerged as successful in elucidating the responses to biotic and abiotic stresses. In Brassica spp., omics technologies such as genomics, transcriptomics, ncRNAomics, proteomics, and metabolomics are well documented, allowing us to gain insights into the dynamic changes that transpired during host-pathogen interactions at a deeper level. So, it is critical that we must review the recent advances in omics approaches and discuss how the current knowledge in multi-omics technologies has been able to breed high-quality clubroot-resistant B. oleracea. This review highlights the recent advances made in utilizing various omics approaches to understand the host resistance mechanisms adopted by Brassica crops in response to the P. brassicae attack. Finally, we have discussed the bottlenecks and the way forward to overcome the persisting knowledge gaps in delivering solutions to breed clubroot-resistant Brassica crops in a holistic, targeted, and precise way.

Alternaria leaf blight and head rot (causal agent: Alternaria brassicicola and other Alternaria species) in broccoli (Brassica oleracea L. var. italica) can lead to decreased yields, reduced head quality, and postharvest losses. While cultural practices and fungicides can decrease disease severity, further work is needed to determine resistance or susceptibility in commercial cultivars. This study evaluated susceptibility of 26 cultivars against A. brassicicola in Fall 2021 and 2022 at two locations in Georgia (Tifton and Watkinsville). Commonly used cultivars in the Eastern U.S. were selected and grown in a randomized complete block design. Approximately 20 days after transplant, plants were inoculated with a conidial suspension of A. brassicicola and monitored for disease development. Foliar disease severity, foliar area under disease progression curve (AUDPC), head disease severity, and yield were determined for each cultivar at each location. Significant differences existed among cultivars (year × location) for foliar AUPDC and head disease severity. Foliar AUPDC ranged from 299 to 1818 for both years and locations and head disease severity ranged from 1 to 81% across both years and locations. In this study, cultivars, ‘Eastern Crown’, ‘Emerald Jewel’, ‘Lieutenant’ and ‘Abrams’, had greater foliar and head disease severity and low marketable yields in both locations and years. The cultivars ‘Vallejo’, ‘Emerald Pride, ‘Burney’, ‘Belstar’ ‘Iron Man’, and ‘Marathon’ exhibited low disease severity across both locations and years and maintained greater marketable yields. Proper selection of commercially-available cultivars could help growers maintain yields in areas with high A. brassicicola pressure.
