Wheat, rice, sorghum and barley are among those monocot plants that can be efficiently transformed by Agrobacterium tumefaciens (Hiei et al.
Understanding the relationship between phylogeny and branching type will increase our understanding of the evolution and ecology of vegetative branching in the palms and will provide a framework for understanding branching in all monocots. The purpose of this study was to (1) identify, define and classify the types of vegetative branching in the palm family Arecaceae and (2) describe the phylogenetic distribution of these branching types in palms.
An unrooted neighbor-joining (bootstrap value = 1000) tree was constructed using MEGA5 on the basis of multiple alignments of conserved domain sequences of the ARF proteins from monocot species (switchgrass, foxtail millet, maize, sorghum, rice, and Brachypodium) and dicot species (Arabidopsis, sweet orange, Chinese cabbage, poplar, Medicago, cotton, soybean, tomato, Grandis, and grape).
Forage quantity and quality from monocot and dicot herb species were evaluated in June 2009 in blocks 2, 3, 4 and 5.
Members of the mastrevirus include species, which infect monocotyledonous (monocot) but it has shifted its mood from monocot to dicotyledonous (dicot) plants.

Scalps, a cauliflower-like structure, are actively proliferating meristems, derived from shoot tip culture and appear as a white bulbous structure and have been reported by several researchers in monocot plants, especially banana [41].
Results in Table 1 indicated dominance of dicot flora over monocot, and among the dicot families, Fabaceae dominated over others.
The collaboration has secured a three year, multi-million pound grant from the Natural Environment Research Council to develop a novel, biodiversity web-resource for monocot plants.

The PAO enzyme is conserved across a wide range of plants, both monocots and dicots, which implies that the gene coding for it was present early in plant evolution.
Furthermore, it was possible to distinguish the main monophyletic groups within angiosperms: Monocots, Magnolidae and the Eudicots.
