Cold stability of microtubules of Mimosa pudica
Biochem Mol Biol Int.
1993 Mar.
Abstract
The unique property of Mimosa pudica microtubules is that they are cold stable in nature. They do not dissociate at 0 degrees C unlike animal microtubules. No other protein fractions of M. pudica are responsible for the cold-resistance property of these microtubules. It seems that tubulin, itself, has an intrinsic cold resistance which makes it unique compared with animal tubulin. Moreover, M. pudica microtubule makes cold-sensitive goat brain microtubule cold-resistant when used in greater than the suboptimal concentration.
