Sentence examples for evolution of grass from inspiring English sources
The genic colinearity of grass genetic maps, physical maps, and contiguous genomic sequences has been a major contributor to almost two decades of study into the structure and evolution of grass genomes.
We assigned three types of gene pair to one of 14 possible evolutionary history categories to uncover their evolutionary dynamics during the evolution of grass genomes.
Possible directions of further detailed studies are proposed, such as the evolution of grass karyotypes, the behaviour of meiotic chromosomes, and the analysis of chromosome distribution at interphase.
The genome of sorghum has recently been sequenced providing a great boost to our knowledge of the evolution of grass genomes and the wealth of diversity within S. bicolor taxa.
Apart from these ambiguities, the nearly complete genomic sequence for the japonica rice genome and the increased availability of genomic resources for other grass species now enables a more detailed understanding of the evolution of grass genomes.

Our finding of episodic rate acceleration in the ancestral grasses accompanied by adaptive molecular evolution has a profound bearing on the evolution of grasses, which form a highly successful group of plants.
This analysis indicated that 11 OGCs had undergone positive selection during the evolution of grasses because they satisfied the following criteria: (1) an estimate of ω > 1 under M8, (2) sites found to be under positive selection, and (3) a statistically significant likelihood ratio test (LRT).
Despite the difference of more than 60 million years of evolution, studies of grass genomes have revealed that significant portions of their chromosomes share the same gene arrangement (Moore et al., 1995).
