(1) Sandersonia aurantiaca is a liliaceous monocotyledon with a bell-shaped corolla formed from fused petals and sepals (tepals).(2) Moreover, there is the CAM-performing Yoshua tree of the genus Yucca with a special monocotyledonous type of secondary thickening.(3) This protein has 11% methionine in its coding sequence and is stable in seed- and non-seed tissues of both monocotyledonous and dicotyledonous plants.(4) Besides this constitutive system, iron reductases have been described in dicotyledons and non-grass monocotyledons that reduce iron prior to uptake.(5) Little is known about the involvement of receptor genes in the ethylene perception of monocotyledonous plants such as rice.(6) Petal abscission was rare in the monocotyledonous flowers tested, and common in the eudicotyledons.(7) Results presented in this study are in good agreement with those reported for other monocotyledons such as maize and rice.(8) In monocotyledons , the expanding region of leaves, where cell division and tissue expansion take place, is located near the leaf insertion point.(9) However GLR-like genes have been identified in other dicotyledonous and monocotyledonous species as well as in gymnosperms, indicating that these genes are of general importance in plant physiology.(10) Lipid transfer proteins are small, basic proteins that have been purified from both monocotyledons and dicotyledons.
