V.Angiosperm

mostly terrestrial but some are hydrophytes like hydrilla, water lilies etc.

Xerophytes-  behave as Ephemerals

Epiphytes-  Orchids

Parasites-  Cuscuta

Saprophytes- Coral root orchid

Kinesin-1 associates preferentially with detyrosylated and acetylated microtubules.

Polyglutamylation and polyglycylation are likely mutually exclusive, so they would not normally occur at the same time & both can enhance microtubule stability,

Detyrosylated microtubules are more stable, because they are more resistant to depolymerization by kinesin-13 and related proteins.

Detyrosylation 

tyrosine can be removed by a carboxypeptidase, where it sequentially removes the C-terminal tyrosines from α-tubulin subunits.

Lysine acetylation 

ε-amino group of a specific lysine of α-tubulin

Microtubules are stabilized against breakage (centrioles, basal bodies, & primary cilia)
