It is known that the meristems responsible for secondary growth in monocot plants differ from the cambia of the gymnospermous and dicotyledonous species.
Monocots constitute approximately 20 per cent (70,000 species) of all higher plants and include numerous groups of the highest conservation, ecological and economic importance, such as grasses, sedges, orchids, palms and aroids.
Givnish and his colleagues sequenced ndhF, a rapidly evolving gene found in the chloroplast, in 35 bromeliads and 16 closely related monocots to infer relationships among present-day bromeliad genera.
I doubt that a minute fraction of the 300-some students that passed through my labs could tell you today what a monocot or a dicot is, or even the difference between a simple and compound leaf.
The branch leading to the monocot split received less than 50% bootstrap support and is, therefore, not strongly supported (Fig.
Louis, MO) have patented a method for conferring tolerance to salt stress and drought stress in a monocot plant including transforming the monocot plant with an expression cassette comprising at least one ABRC unit, a minimal promoter, and a DNA molecule that increases tolerance to salt stress and drought stress in plants, wherein the at least one ABRC unit, the minimal promoter, and a DNA molecule are operably linked together to permit expression of the DNA molecule.
A review by Mengel (1985) on uptake from non-exchangeable K indicated that many monocot plants are nourished by this form of K.
Between the perennials, grasses and dwarf bamboos complete the effect, though you must not overdo them, turning your monocot bed into a wildflower lawn.
He added, "While corn is important in and of itself, these sequences and their functions, combined with the results of our previously completed sequencing projects and our ongoing functional genomics efforts, give our scientists a broad understanding of most of the active genes in both monocot and dicot plant species".
