Brassicaceae (/ˌbræsɪˈkeɪsii/) or Cruciferae (/kruːˈsɪfəri/)[2] is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. ; Blossey, B.; Hoodle, M.; Lyon, S.; Reardon, R., 2010. The seed does not contain endosperm. The leaves along the stem are almost always alternately arranged, rarely apparently opposite. ), Brassica napus (rapeseed, etc. The only exceptions are a few Moricandia species, which have a hybrid system between C3 and C4 carbon fixation, C4 fixation being more efficient in drought, high temperature and low nitrate availability.

Woad (Isatis tinctoria) was used in the past to produce a blue textile dye (indigo), but has largely been replaced by the same substance from unrelated tropical species like Indigofera tinctoria.[31]. northeastern Brazil, the Congo basin, Maritime Southeast Asia and tropical Australasia. The leaf may be seated or have a leafstalk. [6], Flowers may be arranged in racemes, panicles, or corymbs, with pedicels sometimes in the axil of a bract, and few species have flowers that sit individually on flower stems that spring from the axils of rosette leaves. Hairs consist of one cell and occur in many forms: from simple to forked, star-, tree- or T-shaped, rarely taking the form of a shield or scale. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium. Leaves: Alternate, simple or pinnately compound (rarely); exstipulate; reticulate venation. [14][7], There is one superior pistil that consists of two carpels that may either sit directly above the base of the stamens or on a stalk. brassicaceae floral diagram: habit: leaves: inflorescences flowers: fruits: common genera and descriptions of important species. Brassicaceae (often called Cruciferae), the mustard family, is by far the largest family in Brassicales, having 338 genera and 3,710 species found throughout the world.

Brassicaceae 1-Floral formula. Garlic mustard is toxic to several rarer North American Pieris species. You do not currently have access to this article. Biological Control of Invasive Plants in the Eastern United States. Here I review the morphological diversity of the flowers of Brassicaceae and discuss studies addressing the underlying genetic and developmental mechanisms shaping floral diversity. [9] One analysis from 2014 represented the relation between 39 tribes with the following tree. The flowers are usually perfect. In floral formula of Brassicaceae A 2 + 4 represents to MEDIUM. South-America has 40 genera containing 340 native species, Southern Africa 15 genera with over 100 species, and Australia and New-Zealand have 19 genera with 114 species between them. The overall herb layer biodiversity is also drastically reduced, particularly in terms of sedges and forbs. Research has found that removing 80 percent of the garlic mustard infestation plants did not lead to a particularly significant recovery of that diversity. Bittercress (Barbarea vulgaris) also produces triterpenoid saponins. Le nom scientifique latin Brassica serait dérivé d'un mot celte, bresic, qui désignait le « chou »2. The 2–600 ovules are usually along the side margin of the carpels, or rarely at the top. [5] The APG II system, merged Cleomaceae and Brassicaceae. Floral diagram with floral formula (mustard): Important plants of the family: Brassica campestris (mustard) Brassica oleracea botrytis (cauliflower) Brassica oleracea capitata (cabbage) Raphanus sativus (radish) Cherianthus cheiri (wall flower) Economic importance: As vegetables: Few plants like radish, cauliflower, cabbage etc. Don't already have an Oxford Academic account? 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. Please check your email address / username and password and try again. Hybridisation is not unusual in Brassicaceae, especially in Arabis, Rorippa, Cardamine and Boechera. The variously shaped seeds are usually yellow or brown in color, and arranged in one or two rows in each cavity. Trichoplusia ni (cabbage looper) moth is also becoming increasingly problematic for crucifers due to its resistance to commonly used pest control methods. Floral formula and floral. It has long been clear that the Aethionema are sister of the remainder of the family. it is unlikely that such a high level of control can be established and maintained on the whole. Flower is bisexual, it contains 5 stamens, pistil is fused of five carpels, ovary is superior. Create custom Assignments. [13], Species belonging to the Brassicaceae are mostly annual, biennial, or perennial herbaceous plants, some are dwarf shrubs or shrubs, and very few vines. Propagation type:Fruit, partial fruit, seed Distribution: The species of this family are distributed throughout the world but are abundant in North Temperate Zone with Mediterranean as major center.

[30] In addition to being invasive, garlic mustard also is a threat to native North American Pieris butterflies such as Pieris oleracea, as they preferentially oviposit on it, although it is toxic to their larvae. Submit. 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. Revised continuously. Medicinal: Artemisia yields a drug santonine. [19] Several Alyssum species can accumulate nickel up to 0.3% of their dry weight, and may be useful in soil remediation or even bio-mining. The leaves do not have stipules, but there may be a pair of glands at base of leafstalks and flowerstalks. This family includes important agricultural crops, among which many vegetables such as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy, kohlrabi, and gai lan (Brassica oleracea), turnip, napa cabbage, bomdong, bok choy and rapini (Brassica rapa), rocket salad/arugula (Eruca sativa), garden cress (Lepidium sativum), watercress (Nasturtium officinale) and radish (Raphanus) and a few spices like horseradish (Armoracia rusticana), Brassica, wasabi (Eutrema japonicum), white, Indian and black mustard (Sinapis alba, Brassica juncea and B. nigra respectively). Register, Oxford University Press is a department of the University of Oxford. broccoli, cabbage, cauliflower, kale, collards), Brassica rapa (turnip, Chinese cabbage, etc. The filaments are slender and not fused, while the anthers consist of two pollen producing cavities, and open with longitudinal slits. Lachezar A Nikolov, Brassicaceae flowers: diversity amid uniformity, Journal of Experimental Botany, Volume 70, Issue 10, 1 May 2019, Pages 2623–2635, https://doi.org/10.1093/jxb/erz079. [7] Although it can be pollinated, Alliaria petiolata is self-fertile. The fruit is very variable in its other traits. .mw-parser-output table.clade{border-spacing:0;margin:0;font-size:100%;line-height:100%;border-collapse:separate;width:auto}.mw-parser-output table.clade table.clade{width:100%;line-height:inherit}.mw-parser-output table.clade td.clade-label{width:0.7em;padding:0 0.15em;vertical-align:bottom;text-align:center;border-left:1px solid;border-bottom:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-fixed-width{overflow:hidden;text-overflow:ellipsis}.mw-parser-output table.clade td.clade-fixed-width:hover{overflow:visible}.mw-parser-output table.clade td.clade-label.first{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-label.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-slabel{padding:0 0.15em;vertical-align:top;text-align:center;border-left:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-slabel:hover{overflow:visible}.mw-parser-output table.clade td.clade-slabel.last{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-slabel.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-bar{vertical-align:middle;text-align:left;padding:0 0.5em;position:relative}.mw-parser-output table.clade td.clade-bar.reverse{text-align:right;position:relative}.mw-parser-output table.clade td.clade-leaf{border:0;padding:0;text-align:left}.mw-parser-output table.clade td.clade-leafR{border:0;padding:0;text-align:right}.mw-parser-output table.clade td.clade-leaf.reverse{text-align:right}.mw-parser-output table.clade:hover span.linkA{background-color:yellow}.mw-parser-output table.clade:hover span.linkB{background-color:green}, Early classifications depended on morphological comparison only, but because of extensive convergent evolution, these do not provide a reliable phylogeny. Two notable exceptions are exclusive self pollination in closed flowers in Cardamine chenopodifolia, and wind pollination in Pringlea antiscorbutica. The family is less prominent in the Saharo-Arabian Region—65 genera, 180 species of which 62 are endemic—and North America (comprising the North American Atlantic Region and the Rocky Mountain Floristic Region)—99 genera, 780 species of which 600 are endemic -. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Becker, R., Gerber E., Hinz H., Katovich E., Panke B., Reardon R., Renz R., Van Riper L., 2013. [7][8] View Answer. The sister family Cleomaceae has bilateral symmetrical corollas (left is mirrored by right, but stem-side is different from out-side), stipules and mostly palmately divided leaves, and mostly no septum. VIEW MORE. Next in abundance comes the Mediterranean Region, with around 630 species (290 of which are endemic) in 113 genera. 3. About 530 of those 900 species are endemics. Davis, Adam. Published by Oxford University Press on behalf of the Society for Experimental Biology. Pieris rapae and other butterflies of the family Pieridae are some of the best-known pests of Brassicaceae species planted as commercial crops. Turini TA, Daugovish O, Koike ST, Natwick ET, Ploeg A, Dara SK, Fennimore SA, Joseph S, LeStrange M, Smith R, Subbarao KV, Westerdahl BB. Invasive aggressive mustard species are known for being self-fertile, seeding very heavily with small seeds that have a lengthy lifespan coupled with a very high rate of viability and germination, and for being completely unpalatable to both herbivores and insects in areas to which they are not native. [14] The stomata are of the anisocytic type. Parasitoid wasps that feed on such insect herbivores are attracted to the chemical compounds released by the plants, and thus are able to locate their prey. Like the Pieridae, it is capable of converting isothiocyanates into less problematic nitriles. Study of distribution of stomata in the upper and lower surfaces of leaves. Since its introduction in the 19th century, Alliaria petiolata has been shown to be extremely successful as an invasive species in temperate North America due, in part, to its secretion of allelopathic chemicals. Due to polyploidy, some species may have up to 256 individual chromosomes, with some very high counts in the North American species of Cardamine, such as C. diphylla. The number of members of a whorl is written after the symbol for a whorl, ∞ signifies a large and indefinite number. The number of homologous chromosome sets varies from four (n=4) in some Physaria and Stenopetalum species, five (n=5) in other Physaria and Stenopetalum species, Arabidopsis thaliana and a Mathiola species, to seventeen (n=17). Four sepals (light green) in median and lateral positions are followed by four alternating petals (red). The energy penalty for synthesising all these glucosinolates may be as high as 15% of the total needed to produce a leaf. A floral formula is a symbolic representation of different floral parts, their numbers, arrangement pattern and how they are related.
