Compositional gradients in Gramineae genes.
In this study, we describe a property of Gramineae genes, and perhaps all monocot genes, that is not observed in eudicot genes. Along the direction of transcription, beginning at the junction of the 5'-UTR and the coding region, there are gradients in GC content, codon usage, and amino-acid usage. The magnitudes of these gradients are large enough to hinder the annotation of the rice genome and...
متن کاملIsoenzymatic Variation in Zea (Gramineae)
An average of 14(7-34) plants each for 61 different collections of Zea (maize and its wild relatives, the teosintes) were studied for 12 enzyme systems coded for by 21 loci. Principal component and cluster analyses based on allele frequencies showed Zea can be divided into two major groups: 1) sect. Luxuriantes, including Z. perennis, Z. diploperennis, and Z. luxurians; and 2) sect. Zea (in par...
متن کاملA Y genome specific STS marker in Pseudoroegneria and Elymus species (Triticeae: Gramineae).
The tribe Triticeae Dumortier in the grass family (Poaceae) includes the most important cereal crops (e.g., wheat, barley, and rye) and some economically important forage grasses. Elymus L. is the largest and most complex genus in the Triticeae tribe with approximately 150 species occurring worldwide. The genomic constitutions of approximately 40% of Elymus species are unknown and some have unv...
متن کاملThe distribution of genes in the genomes of Gramineae (chromosomesyisochoresyplants)
Recent investigations showed that most maize genes are present in compositional fractions of nuclear DNA that cover only a 1–2% GC (molar fraction of guanosine plus cytosine in DNA) range and represent only 10–20% of the genome. These fractions, which correspond to compositional genome compartments that are distributed on all chromosomes, were collectively called the ‘‘gene space.’’ Outside the...
