Cold stability of microtubules of Mimosa pudica.
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.
