Trx proteins were classified into 4 classes, Class III-1 to Class III-4 which were further divided into subclasses. (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 RCC299; 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
