FTR — Arabidopsis thaliana

Summary

AT1G80350 (FTR) in Arabidopsis thaliana encodes a microtubule-severing AAA ATPase (katanin small subunit) with microtubule binding and ATP hydrolase activity. The gene is associated with microtubule dynamics, including severing, shortening, and organization of cytoplasmic and cortical microtubules, as well as preprophase band assembly, prophase, metaphase, anaphase, and interphase. It is associated with nuclear migration along microfilaments, cell-cell adhesion, differential growth, leaf pavement cell development, and epidermal cell differentiation. Associations with traits include seed morphology, seed set percent, cellulose content, root thickness, root development, leaf trichome density, petal morphology, stamen length, cotyledon morphology, cell elongation, cell cycle, embryo development, organ identity, phyllotaxy, root phototropism, and photochemical quenching. The protein localizes to the katanin complex, microtubule cytoskeleton, cell plate, and chloroplast envelope. Studies of related genes in other species link the family to fruit length and elongation.
