WebMar 1, 2013 · Background Chromoviruses are one of the three genera of Ty3-gypsy long terminal repeat (LTR) retrotransposons, and are present in high copy numbers in plant genomes. They are widely distributed... Chromoviruses have long terminal repeats in direct orientation at each end. The genes within the chromovirus encode Gag and Pol proteins. The following enzymatic domains in pol gene are indicated: PR, protease; RT, reverse transcriptase; RH, RNaseH; IN, integrase; and CHR, chromodomain. WebInterestingly, all plant metaviruses devoid of additional coding domains seem to be chromoviruses. It is therefore likely that the classification of Metaviridae will be reconsidered in future, to separate the two groups of metaviruses and recognize the existence of the chromodomain. how are fears developed
