“…However, they are of great importance for resistance to abiotic and biotic stresses and have the potential to improve resilience in modern cultivars ( Quezada-Martinez et al., 2021 ). In addition, some of the wild Brassicas could even serve as a source of a new crop ( Razzaq et al., 2021 ).…”

“…Even if the natural regions of origin are not considered, it is obvious that the majority of species of the Brassica gene pool are underrepresented in European genebanks although collecting missions were carried out in the 1970s ( Razzaq et al., 2021 ). To solve this problem, a global strategy for the conservation of Brassica genetic resources was developed by the Global Crop Diversity Trust ( Allender and Giovannini, 2023 ), confirming the importance of CWRs.…”

Rapeseed is one of the most important agricultural crops and is used in many ways. Due to the advancing climate crisis, the yield potential of rapeseed is increasingly impaired. In addition to changing environmental conditions, the expansion of cultivated areas also favours the infestation of rapeseed with various pests and pathogens. This results in the need for continuous further development of rapeseed varieties. To this end, the potential of the rapeseed gene pool should be exploited, as the various species included in it contain promising resistance alleles against pests and pathogens. In general, the biodiversity of crops and their wild relatives is increasingly endangered. In order to conserve them and to provide impulses for breeding activities as well, strategies for the conservation of plant genetic resources are necessary. In this study, we investigated to what extent the different species of the rapeseed gene pool are conserved in European genebanks and what gaps exist. In addition, a niche modelling approach was used to investigate how the natural distribution ranges of these species are expected to change by the end of the century, assuming different climate change scenarios. It was found that most species of the rapeseed gene pool are significantly underrepresented in European genebanks, especially regarding representation of the natural distribution areas. The situation is exacerbated by the fact that the natural distributions are expected to change, in some cases significantly, as a result of ongoing climate change. It is therefore necessary to further develop strategies to prevent the loss of wild relatives of rapeseed. Based on the results of the study, as a first step we have proposed a priority list of species that should be targeted for collecting in order to conserve the biodiversity of the rapeseed gene pool in the long term.

“…Members of the family Brassicaceae family especially the vegetable crops, prefer to grow under cooler temperate conditions (15–20°C), with high humidity, but some species are also found to grow also under subtropical and even tropical zones ( Fahey, 2016 ; Lin et al., 2018 ; Razzaq et al., 2021 ). For example Chinese cabbage plants grow well at a temperatures range of 13–20°C but prefer warmer growing conditions and often bolt at lower temperatures ( Salehi et al., 2021 ).…”

The past decade has seen an observable loss of plant biodiversity which can be attributed to changing climate conditions, destroying ecosystems to create farmlands and continuous selective breeding for limited traits. This loss of biodiversity poses a significant bottleneck to plant biologists across the globe working on sustainable solutions to address the current barriers of agricultural productivity. Plant genetic resources centers or genebanks that conserve plant germplasm can majorly contribute towards addressing this problem. Second only to soybean, Brassica remains the largest oil-seed crop and is cultivated across 124 countries, and FAO estimates for a combined gross production values of broccoli, cabbages, cauliflower, mustard and rape seeds stands at a staggering 67.5 billion US dollars during the year 2020. With such a global status, wide variety of uses and more recently, growing importance in the health food sector, the conservation of diverse genetic resources of Brassica appeals for higher priority. Here we review the current status of Brassica conservation across plant genebanks. At present, at least 81,752 accessions of Brassica are recorded to be conserved in 148 holding institutes spread across only 81 countries. Several aspects that need to be addressed to improve proper conservation of the Brassica diversity was well as dissemination of germplasm are discussed. Primarily, the number of accessions conserved across countries and the diversity of Brassica taxa most countries has been highly limited which may lead to biodiversity loss in the longer run. Moreover, several practical challenges in Brassica germplasm conservation especially with respect to taxonomic authorities have been discussed. The current review identifies and highlights areas for progress in Brassica conservation, which include but are not limited to, distribution of conserved Brassica biodiversity, challenges faced by conservation biologists, conservation methods, technical hurdles and future avenues for research in diverse Brassica species.

Chinese broccoli [Brassica oleracea var. alboglabra (L. H. Bailey) Musil] is an annual herbaceous healthy vegetable plant mainly cultivated in southern China. Previous studies have been primarily focused on investigating the nutritional ingredients of this plant, little is known about its medicinal potentials. Here we report the profiling of sulforaphane, an active ingredient with potent anticancer activities, in 47 Chinese broccoli germplasms collected from China and some southeast-Asian countries. High-performance liquid chromatography technology was used to systemically quantify the sulforaphane content in leaf, stem, and flower bud clusters of all 47 Chinese broccoli germplasms. The results indicated a diverse distribution pattern of sulforaphane among different tissues. Flower bud contained the highest average of sulforaphane, roughly twice as much as in leaf and stem tissues. Interestingly, different germplasms exhibited great differences in terms of sulforaphane abundance. Germplasm BOK15-20 is extremely rich in sulforaphane in all tissues tested, ∼2,500 times of BOK15-15 in leaf, 66 times of BOK15-42 in the stem, and 77 times of BOK15-40 in flower bud. The tremendous disparity of sulforaphane content among different germplasms suggests considerable variations in germplasms' medicinal potentials. In addition, we systemically characterized a series of morphological and phenotypic traits of all 47 Chinese broccoli germplasms. Cluster analysis through NTSYSpc v2.2 showed that the 47 germplasms were classified into five different groups, respectively, based on sulforaphane content and qualitative phenotypic traits. Our results not only confirmed the medicinal values of Chinese broccoli but also provided crucial information that will eventually benefit future germplasm development and new variety breeding.
