The area of origin of the family is possibly the Irano-Turanian Region, where approximately 900 species occur in 150 different genera. Since there are so many terms about flowers, and at the same time, flower structure and diversity always were of immense importance in botany, two specific ways were developed to make flower description more compact. Eubanks, HM.D., Hoffmann, J.H., Lewis, E.E., Liu, J., Melnick, R., Michaud, J.P., Ode, P., Pell, J.K., 2017. The receptacle carries a variable number of nectaries, but these are always present opposite the base of the lateral stamens. Alfred Barton Rendle placed the family in the order Rhoedales, while George Bentham and Joseph Dalton Hooker in their system published from 1862–1883, assigned it to their cohort Parietales (now the class Violales). The blade is entire or has an indent at the tip, and may sometimes be much smaller than the claws. Most are herbaceous plants, some shrubs, with simple, although sometimes deeply incised, alternatingly set leaves without stipules or in leaf rosettes, with terminal inflorescences without bracts, containing flowers with four free sepals, … Given that not one of an estimated 76 species that prey on the plant has been approved for biological control in North America and the variety of mechanisms the plant has to ensure its dominance without them (e.g. Root System: Taproot system.

Each flower has four free or seldomly merged sepals, the lateral two sometimes with a shallow spur, which are mostly shed after flowering, rarely persistent, may be reflexed, spreading, ascending, or erect, together forming a tube-, bell- or urn-shaped calyx. When the cell is damaged, the myrosinases hydrolise the glucosinolates, leading to the synthesis of isothiocyanates, which are compounds toxic to most animals, fungi and bacteria. Bracteate ⊕ Actinomorphic (radial symmetry) ⚥ Bisexual. Studies on the genetic basis of morphological diversity, enabled by extensive genetic tools and genomic resources and the close phylogenetic distance among mustards, have revealed a mosaic of conservation and divergence in numerous floral traits. it is unlikely that such a high level of control can be established and maintained on the whole. Turini TA, Daugovish O, Koike ST, Natwick ET, Ploeg A, Dara SK, Fennimore SA, Joseph S, LeStrange M, Smith R, Subbarao KV, Westerdahl BB.

It has long been clear that the Aethionema are sister of the remainder of the family. There may be one persistent style that connects the ovary to the globular or conical stigma, which is undivided or has two spreading or connivent lobes. Habit: Annual Perennial or everlasting; shrubs, herbs, and trees. When identifying flower parts, it is best to start on the outside of the flower and work towards the middle like this: sepals, petals, stamens, and pistil(s). U can like my Facebook page ie. Economic Importance----- ----- Food: Some plants of this family are used as food Sonic of these are lettuce (fsi.–), roots and leaves of cichory. The cabbage aphid (Brevicoryne brassicae) stores glucosinolates and synthesises its own myrosinases, which may deter its potential predators.[19]. [13], Species belonging to the Brassicaceae are mostly annual, biennial, or perennial herbaceous plants, some are dwarf shrubs or shrubs, and very few vines.

Woad (Isatis tinctoria) was used in the past to produce a blue textile dye (indigo), but has largely been replaced by the same substance from unrelated tropical species like Indigofera tinctoria.[31]. These schematic diagrams replace long descriptions or complicated drawings as a tool for understanding floral structure and evolution. Hybridisation between species originating in Africa and California, and subsequent polyploidisation is surmised for Lepidium species native to Australia and New Zealand. Elsevier. View Answer. [5] The Cleomaceae and Brassicaceae diverged approximately 41 million years ago. [7], Almost all Brassicaceae have C3 carbon fixation. A floral formula can define as the numeric and symbolic expression, which reveals the flower morphological characteristics by employing different symbols, letters and figures.It is the conventional method accustomed to formulate the structure of the flower. Vegetable oil is produced from the seeds of several species such as Brassica napus (rapeseed oil), perhaps providing the largest volume of vegetable oils of any species.
