This list of sequenced plant genomes contains plant species known to have publicly available complete genome sequences that have been assembled, annotated and published. Genomes: organization and comparisons. Dense plant cultivation is an efficient approach to improve maize production by maximizing the utilization of energy and nutrients. Plant RNA viruses show a wide variation in their genome structure and organisation and may have different terminal structures such as cap structures or genome-linked proteins (VPg) at the 5' end, and a poly(A)-tail or tRNA-like structure at the 3' end of their RNA (reviewed by Goldbach et al., 1991). Bioinformatics- Introduction and Applications. In many plant species with relatively large genomes, chromosomes during interphase adopt Rabl configuration (Cowan et al., 2001).This term describes an interphase chromosome arrangement in which centromeres and telomeres are located at opposite sides of the nucleus ().This configuration is thought to be a remnant of a preceding anaphase.
