Dicots, families

The vascular flora of the Juan Fernandez Islands consists of 361 species and includes 53 ferns, 65 monocots, and 243 dicots. There are 126 endemic species, 12 endemic genera, and one endemic family, Lactoridaceae (Stuessy et ak, 1992). A considerable amount of work has gone into attempts to establish evolutionary... 

C4-forms might simply reflect the dicot/monocot branches of the plant kingdom. It will be essential to obtain sequences for more CAM enzymes from different plant families, more sequences from C3-forms and, very importantly, also sequences from dicot C4-forms. 

Recent reviews122 124 have reported the natural occurrence of more than 150 sulfated flavonoids in some 300 species belonging to several dicot and monocot families. These are mostly mono- to tetrasulfate esters of common hydroxyflavones and hydroxyflavonols and their methyl ethers and less commonly of their... 

A phylogenetic tree was constructed by selecting one CHS each from various families of dicots, monocots, gymnosperms and ferns (42). In addition, all plant type III PKSs that functionally differ from CHS were included (Figure 6). 

Abstract Synthesis of polyhydroxyalkanoates (PHAs) in crop plants is viewed as an attractive approach for the production of this family of biodegradable plastics in large qnantities and at low costs. Synthesis of PHAs containing various monomers has so far been demonstrated in the cytosol, plastids, and peroxisomes of plants. Several biochemical pathways have been modified to achieve this, including the isoprenoid pathway, the fatty acid biosynthetic pathway, and the fatty acid P-oxidation pathway. PHA synthesis has been demonstrated in a number of plants, including monocots and dicots, and np to 40% PHA per gram dry weight has been demonstrated in Arabidopsis thaliana. Despite some successes, production of... 

CSLC, CSLD, and CSLE. Rice appears to lack the CSLG and CSLB families and possess two additional families CSLF CSLH. Monocots and dicots do possess different cell wall architectures (Carpita and McCann 2000). Whether this classification of the CSLs truly represents a division between the monocots and dicots requires further study since biochemical functions have not yet been ascribed to the CSL proteins. Interestingly, the C5Ls form two separate clades when compared with the CESA genes from plants and other organisms. The... 

Occurrence in Non-solanaceous Taxa. Steroidal saponins are widespread in the plant kingdom, especially within the monocots (e.g., Agavaceae, Asparagaceae, Dioscoreaceae, Liliaceae). However, they also occur - though much rarer - within the dicots (e.g., Fabaceae, Plantaginaceae, Zygophyllaceae), where triterpenoid saponins are more liequent [occurrence documented in about 60 families (Teuscher and Lindequist 1994)].
