(redirected from Eudicot)


 (yo͞o′dī-kŏt′l-ēd′n) or eu·di·cot (yo͞o-dī′kŏt′)
Any of numerous flowering plants having two cotyledons in the seed, pollen grains with three pores, and usually the capacity for secondary growth, leaves with reticulate venation, and flower parts that are in multiples of four or five.

[eu-, true (since the eudicotyledons form a clade excluding certain other dicotyledonous groups, such as the magnoliids) + dicotyledon.]

In the large and diverse eudicot family Ericaceae with a nearly worldwide distribution, two of nine subfamilies, Pyroloideae and Monotropoideae, contain partial and full mycoheterotrophs, respectively [73].
They obeyed 26 secret memos that forbade by the Brazilian Ministry of Foreign Affairs to grant visas to during the terms of Presidents Getulio Vargas and Eudicot Gaspar Dutra between 1937 and 1950.
In western North America, species representing at least 15 eudicot families have evolutionarily converged on a narrowly defined suite of floral traits adapted for hummingbird attraction, foraging and pollination (Grant and Grant, 1968), including 10 or more lineages within Penstemon (Wilson et al., 2007).
The plant lineage that includes the sacred lotus forms a separate branch of the eudicot family tree, and so lacks a signature triplication of the genome seen in most other members of this family, said University of Illinois plant biology and Institute for Genomic Biology professor Ray Ming, who led the analysis with Jane Shen-Miller, a plant and biology professor at the University of California at Los Angeles (who germinated a 1,300-year-old sacred lotus seed); and Shaohua Li, director of the Wuhan Botanical Garden at the Chinese Academy of Sciences.
azoriea, therefore, represent new additions to the list of torus-containing eudicot species.
* Polemoniales, a "eudicot" or "dicot" order, the phlox order.
However, its pollen appears to be tricolpate, suggesting that it may be a fragment of a eudicot flower; the fact that the sites of anther dehiscence appear not to be lateral but rather in the median plane also suggests it was part of a larger flower.
Several interesting features have been found in the trees that we reconstructed: (1) the eukaryotes are clearly separated from the prokaryotes and (2) plants and animals are grouped together, even the eudicot plants (A.
