  1. Su(var) proteins were classified into 3 classes, Class IV-1, Class IV-2 and Class Orphan which were further divided into subclasses. The detailed domain arrangement with additional domains are shown. (At- Arabidopsis thaliana; Os-Oryza sativa; Pa-Picea abies; Sm-Selaginella meollendorffii; Pp-Physcomitrella patens; Mp-Marchantia polymorpha; Nm-Nitella mirabilis; Kf-Klebsormidium flaccidium; Mr.-Micromonas RCCC; Mpu-Micromonas pusila; Ot-Ostreococcus tauri; Ol-Ostreococcus lumiferans; Cv-Chlorella vulgaris; Cr-Chlamydomonas reinhardtii; Vc-Volvox carteri; Cp-Cyanophora paradoxa. Plus sign (+) and minus sign (−) indicate presence and absence of an above mentioned domain architecture
