The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
The number of pollen grain furrows or pores helps classify the flowering plants, with eudicots having three colpi (tricolpate), and other groups having one sulcus. [8] [7] Pollen apertures are any modification of the wall of the pollen grain. These modifications include thinning, ridges and pores, they serve as an exit for the pollen contents ...
Arabidopsis (rockcress) is a genus in the family Brassicaceae.They are small flowering plants related to cabbage and mustard.This genus is of great interest since it contains thale cress (Arabidopsis thaliana), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced.
The eudicots are the largest monophyletic group within the dicotyledons. They are distinguished from all other flowering plants by the structure of their pollen . Other dicotyledons and the monocotyledons have monosulcate pollen (or derived forms): grains with a single sulcus.
Botanical illustration of Arabidopsis lyrata (1913). Arabidopsis lyrata are diploid plants that have a life span of two or more years, small white flowers and highly distinct basal leaves with a height of 10–40 centimetres (4–16 in). [1]
Though traditionally recognized as a large genus with many Old World and New World members, more recent evaluations of the relationships among these species using genetic data suggest there are two major groups within the old genus Arabis. These two groups are not each other's closest relatives, so have been split into two separate genera.
In phylogenetic nomenclature, the Pentapetalae are a large group of eudicots that were informally referred to as the "core eudicots" in some papers on angiosperm phylogenetics. [2] They comprise an extremely large and diverse group accounting for about 65% of the species richness of the angiosperms , with wide variability in habit , morphology ...
Arabis allionii is a species of flowering plant in the family Brassicaceae, native to the mountains of central and southern Europe and southern Turkey. [1] The Royal Horticultural Society lists it as a garden plant for attracting pollinators, but gives its common name as "Siberian wallflower", suggesting that they have it confused with Erysimum × marshallii.
