Monocot
Definition:
Example Sentences:
(1) Efficient splicing of the mRNA for this coding region was observed in the infected dicotyledonous (dicot) hosts bean and tobacco despite the intron having an A + U content (57%) more typical of geminiviruses of monocot plants.
(2) Because this monocot gene promoter appeared to be under stringent tissue-specific control, a hybrid promoter approach using a nopaline synthase (nos) promoter was employed.
(3) The graminaceous monocots, including the economically important cereals, seem to be refractory to infection by Agrobacterium tumefaciens, a natural gene transfer system that has been successfully exploited for transferring foreign genes into higher plants.
(4) The topology of the tree indicated that, at least in monocots such as maize and sorghum, the genes for the C4-form and C3-form isozymes diverged from their common ancestral gene earlier than the monocot-dicot divergence (about 2 x 10(8) yr ago), though the divergence of maize (C4 plant) from wheat (C3 plant) is supposed to have occurred much later (6 x 10(7) yr ago).
(5) The DNA sequence composition of 526 dicot and 345 monocot intron sequences have been characterized using computational methods.
(6) Whereas most dicot nuclei contain one or two predominant forms of U2 snRNA and a small number of U4 snRNAs, monocot nuclei contain multiple forms of U2 snRNA ranging from 208 to 260 nucleotides and multiple forms of U4 snRNA from 159 to 176 nucleotides.
(7) This finding distinguishes WDV from other monocot-infecting geminiviruses studied so far which were shown to encode two 3' co-terminal transcripts capable of expressing either the V1 or V2 ORF.
(8) This complexity can best be appreciated by considering xyloglucan, a hemicellulose present in the cell wall of both monocots and dicots, and rhamnogalacturonan II (RG-II) and rhamnogalacturonan I (RG-I), two structurally unrelated pectic polysaccharides.
(9) The 5' splice site consensus sequences developed for the monocot and dicot introns differ in their ability to base pair with conserved nucleotides present at the 5' end of many U1 snRNAs.
