		Dicotyledons or dicots are flowering plants whose seed contains two embryonic leaves or cotyledons.
		Flowering plants or angiosperms that are not dicotyledonous are monocotyledonous: having one embryonic leaf.
		It is believed that monocots evolved from dicots, and as such the latter form a paraphyletic group, i.e.

		Dicotyledons or "dicots" are a group of flowering plants whose seed typically contains two embryonic leaves or cotyledons.
		This means that dicotyledons no longer are regarded as a "good" group, and the names "dicotyledons" and "dicots" are no longer to be used, at least in a taxonomic sense.
		Other dicotyledons and monocotyledons have monosulcate pollen, or forms derived from it, whereas eudicots have tricolpate pollen, or derived forms, the pollen having three or more pores set in furrows called colpi.

		The dicotyledons are so named because sprouting seeds have two primary leaves or cotyledons.
		Other common features of the dicots are leaves with branching or net veining and flowers with four or five tepals or multiples of these.
		Examples of dicotyledons would be roses, most fruit trees such as apples, pears, cherries and peaches.

	Title of Invention: Rice chitinase promoter
		In dicotyledonous plants, extensive studies have shown that microbial attack or elicitor treatment induces the transcription of a battery of genes encoding proteins involved in these defense responses, as part of a massive switch in the overall pattern of gene expression.
		While chitinases from dicotyledons have been well characterized, and many of the corresponding genes have been isolated, there is little information available on the structure and expression of chitinase genes from monocotyledons.
		In the invention method for inducing gene expression in monocotyledon (and dicotyledon) plants, plant material containing DNA constructs under the expression control of invention monocotyledon regulatory sequences is subjected to conditions which induce transcription of the DNA construct.

		The Dicotyledons are named for the two seed leaves or cotyledons produced from a sprouting seed with about 200,000 species within the group.
		Molecular analysis suggests that the Dicotyledons do not form a coherent taxonomic group and in future may be divided into Eudicots whose pollen has three grooves and Palaeodicots whose pollen has a single groove.
		Common features among Dicotyledons are vascular bundles forming a ring within the stem, flowers with parts in multiples of four or five, leaves with a branched network of veins, roots develping from the radicle and pollen grains with three grooves.

		In fact the forms of this family are rather diverse, and they are the asterales group in true dicotyledons.
		In short, after branching off from the ancestor they share with the Hypericum, which has a general dicotyledon shape, the podostemaceae rapidly evolved into a form enabling it to cope with their environment.
		They have lost the characteristics of the dicotyledon, including a meristem on the shoot apex and radicules, resulting in vague, irregular forms.

	Comparing Monocots and Dicots
		The basic food supply of the world is derived from the seeds and fruits of angiosperms (rice, wheat, corn) and fibers, wood, drugs, and other products of great economic value.
		The studies by John Ray in the 1700's on the structure of seeds led him to discover the difference between monocotyledon (monocots) and dicotyledon (dicots) plants.
		There are estimated to be about 165,000 different types of dicots and 55,000 types of monocots.
