Background Zn hyperaccumulating plants reach Zn concentrations in their leaves that are several hundredfold higher than the target values set for Zn-biofortified crops. Scope This extreme trait is relevant for Zn biofortification in various ways that are being discussed based on what is known about Zn hyperaccumulating plants.Conclusions First, Zn hyperaccumulation is the result of changes in metal homeostasis networks shared by all higher plants. It is not strictly dependent on high Zn levels in the soil. Thus, mechanistic insights gained from the study of Zn hyperaccumulators can support the breeding and engineering of Zn-biofortified crops. Second, certain plant families, the Brassicaceae in particular, appear to be genetically predispositioned to evolve enhanced Zn accumulation, suggesting the existence of intermediate species with elevated Zn concentrations in their leaves below the hyperaccumulation threshold or the potential to breed for such plants. This calls for extended screening especially among potential vegetable crops, ideally guided by knowledge about the at least partially convergent evolution of Zn hyperaccumulation. Third, the introduction of leafy vegetables with high Zn concentrations or even of Zn hyperaccumulator leaves into diets may represent a valid complementary biofortification approach.

“…This crop is also being exploited for biodiesel as a source of a renewable energy (Warwick et al, 2006). It consists of the two homologous genomes, B and C, and may have originated as an allotetraploid species as a result of spontaneous hybridization between diploid species; Brassica nigra (2 n = 2 x = 14, genome BB) and Brassica oleracea (2 n = 2 x = 18, genome CC) in Ethiopia (Nagaharu, 1935; Lukens et al, 2004; Warwick, 2011). B. carinata harbors useful genes for resistance to abiotic and biotic stresses (Getinet et al, 1996), and therefore has been used as a donor for introgression of genes to improve and widen the gene pool of Brassica rapa, Brassica napus , and Brassica juncea germplasm (Meng et al, 1998; Xiao et al, 2010; Wei et al, 2016).…”

Brassica carinata (BBCC) is an allotetraploid in Brassicas with unique alleles for agronomic traits and has huge potential as source for biodiesel production. To investigate the genome-wide molecular diversity, population structure and linkage disequilibrium (LD) pattern in this species, we genotyped a panel of 81 accessions of B. carinata with genotyping by sequencing approach DArTseq, generating a total of 54,510 polymorphic markers. Two subpopulations were exhibited in the B. carinata accessions. The average distance of LD decay (r2 = 0.1) in B subgenome (0.25 Mb) was shorter than that of C subgenome (0.40 Mb). Genome-wide association analysis (GWAS) identified a total of seven markers significantly associated with five seed quality traits in two experiments. To further identify the quantitative trait loci (QTL) for important agronomic and seed quality traits, we phenotyped a doubled haploid (DH) mapping population derived from the “YW” cross between two parents (Y-BcDH64 and W-BcDH76) representing from the two subpopulations. The YW DH population and its parents were grown in three contrasting environments; spring (Hezheng and Xining, China), semi-winter (Wuhan, China), and spring (Wagga Wagga, Australia) across 5 years for QTL mapping. Genetic bases of phenotypic variation in seed yield and its seven related traits, and six seed quality traits were determined. A total of 282 consensus QTL accounting for these traits were identified including nine major QTL for flowering time, oleic acid, linolenic acid, pod number of main inflorescence, and seed weight. Of these, 109 and 134 QTL were specific to spring and semi-winter environment, respectively, while 39 consensus QTL were identified in both contrasting environments. Two QTL identified for linolenic acid (B3) and erucic acid (C7) were validated in the diverse lines used for GWAS. A total of 25 QTL accounting for flowering time, erucic acid, and oleic acid were aligned to the homologous QTL or candidate gene regions in the C genome of B. napus. These results would not only provide insights for genetic improvement of this species, but will also identify useful genetic variation hidden in the Cc subgenome of B. carinata to improve canola cultivars.

“…Brassicaceae is one of the most diverse plant families, comprising 49 tribes, 321 genera, and over 3660 species (Al-Shehbaz, 2012), including economically important edible and industrial oilseed and vegetable crops as well as highly diverse wild germplasm (Warwick, 2011). The members of this family are distributed worldwide .…”

Polyploid Evolution of the Brassicaceae during the Cenozoic Era

The Brassicaceae (Cruciferae) family, owing to its remarkable species, genetic, and physiological diversity as well as its significant economic potential, has become a model for polyploidy and evolutionary studies. Utilizing extensive transcriptome pyrosequencing of diverse taxa, we established a resolved phylogeny of a subset of crucifer species. We elucidated the frequency, age, and phylogenetic position of polyploidy and lineage separation events that have marked the evolutionary history of the Brassicaceae. Besides the well-known ancient a (47 million years ago [Mya]) and b (124 Mya) paleopolyploidy events, several species were shown to have undergone a further more recent (;7 to 12 Mya) round of genome multiplication. We identified eight whole-genome duplications corresponding to at least five independent neo/mesopolyploidy events. Although the Brassicaceae family evolved from other eudicots at the beginning of the Cenozoic era of the Earth (60 Mya), major diversification occurred only during the Neogene period (0 to 23 Mya). Remarkably, the widespread species divergence, major polyploidy, and lineage separation events during Brassicaceae evolution are clustered in time around epoch transitions characterized by prolonged unstable climatic conditions. The synchronized diversification of Brassicaceae species suggests that polyploid events may have conferred higher adaptability and increased tolerance toward the drastically changing global environment, thus facilitating species radiation.
