“…& Durieu, Crambe L., Cakile Mill., Savignya DC., “ Nigra ”, and “ Oleracea ” (Arias and Pires 2012), but several genera remain poly- and paraphyletic such as Brassica L. and Diplotaxis DC. (Arias and Pires 2012), Raphanus L. (Ziffer-Berger et al 2014), or Sinapis L. (Arias and Pires 2012). The tribe Brassiceae is not only characterized by an ancient triploidization, but extensive hybridization and reticulate evolution may have been involved while forming numerous polyploids.…”

Zahora ait-atta Lemmel & M.Koch, a new species from the Moroccan Sahara, is described and documented here and constitutes a monotypic new genus. The new taxon belongs to the tribe Brassiceae (Brassicaceae), and cytogenetic and phylogenetic analyses reveal that this diploid species has a remote status of Miocene origin in the northwestern Sahara Desert. We examined the morphological differences between morphologically related genera and provide photographs of the new species. The new genus may play a key role in future Brassica-Raphanus crop research since it is placed phylogenetically at the base of a generically highly diverse clade including Raphanus sativus, and it shows affinities to various Brassica species.

“…The crop R. sativus is divided into four major types—two root crops (European radish and Asian daikon) and two fruit crops (Oilseed and edible‐pod Rattail). R. pugioniformis is a little‐studied endemic of the eastern Mediterranean (Ziffer‐Berger, Hanin, Fogel, Mummenhoff, & Barazani, ). The relationships among these species are not well‐resolved (Ziffer‐Berger et al., ), but an analysis of cDNA sequence from one population of each of eight Raphanus taxa (not including R. pugioniformis ) provided strong support for the monophyly of the crop cultivars, as well as monophyly of native and weedy R. r. raphanistrum (Shen et al., ).…”

Approximately 200 weed species are responsible for more than 90% of crop losses and these comprise less than one percent of all named plant species, suggesting that there are only a few evolutionary routes that lead to weediness. Agricultural weeds can evolve along three main paths: they can be escaped crops, wild species, or crop‐wild hybrids. We tested these three hypotheses in weedy radish, a weed of small grains and an emerging model for investigating the evolution of agricultural weeds, using 21 CAPS and SSR markers scored on 338 individuals from 34 populations representing all major species and sub‐species in the radish genus Raphanus. To test for adaptation of the weeds to the agricultural environment, we estimated genetic differentiation in flowering time in a series of common garden experiments with over 2,400 individuals from 43 populations (all but one of the genotyped populations plus 10 additional populations). Our findings suggest that the agricultural weed radish R. r. raphanistrum is most genetically similar to native populations of R. r. raphanistrum and is likely not a feral crop or crop hybrid. We also show that weedy radish flowers more rapidly than any other Raphanus population or cultivar, which is consistent with rapid adaptation to the frequent and severe disturbance that characterizes agricultural fields.

A study was conducted to explore phenotypic variation in two Raphanus species: Raphanus raphanistrum and R. pugioniformis, which are found in the East-Mediterranean region. For each species, a 100m2 area representing their respective habitats was selected. Morphological characterization of the whole plant, leaves, and fruits was carried out in the field. The study analyzed morphological characteristics of R. pugioniformis populations during both flowering and maturity stages. It also compared the maturity stage characteristics. The examined characteristics included plant height, flower to plant ratio, leaf to plant ratio, leaf length, flower color, tip to pod ratio, seed to fruit ratio, fruit parameters (length, width, and weight), and the number of primary and secondary branches. Results revealed that plant height, tip to pod ratio, and fruit length increased from the flowering stage to the maturity stage. However, the number of primary and secondary branches and the ratio of seeds to fruit remained consistent between the flowering and maturity stages. R. raphanistrum exhibited greater plant height, flower to plant ratio, leaf to plant ratio, tip to pod ratio, seed to fruit ratio, fruit length, fruit width, fruit weight, and number of branches. The study examined also the dry weight and nitrogen, phosphorous, and potassium contents in leaves, stems, and seeds. It was found that R. pugioniformis had higher nitrogen and phosphorous contents in the leaves, stem, seeds, and whole plant compared to R. raphanistrum. R. pugioniformis exhibited higher nitrogen and phosphorous contents in the leaves, seeds, and whole plant. Similar trends were observed for potassium content. In summary, the study highlighted the phenotypic variation between R. raphanistrum and R. pugioniformis populations in the East-Mediterranean region. Differences were observed in various morphological characteristics, dry weight, and nutrient contents, providing valuable insights into the contrasting traits and adaptations of these closely related Raphanus species.
