Abstract
This entry includes a group of plant microtubule-associated proteins, including TORTIFOLIA1/SPIRAL2 and SPIRAL2-like (SP2L) from Arabidopsis. They regulate the orientation of cortical microtubules and the direction of organ growth [ 1 ].
TORTIFOLIA1-like protein 1 (also known as SPIRAL2) is a microtubule-associated protein (MAP) that regulates the orientation of cortical microtubules and the direction of organ growth [ 2 ] and may regulate katanin-based microtubule (MT) severing [ 2 ]. During virus infection, it may stabilize MT crossovers to support the formation and intercellular spread of the viral RNA complexes [ 3 ].
