Stomates open and close in response to a variety of environmental
parameters.

Sadhna Purohit et al reported in Biochem and Biophys Res Com Vol. 186,
No. 2, 1992 Pages 652-658, that a high-affinity guard cell specific
ABA-binding protein with three sub units of estimated Mr 20,000,
19,300, and 14,300 was located on the plasma membrane of guard cell
protoplasts.

I am looking for evidence or citations confirming this ABA-binding
protein is in fact a plant transglutaminase.  

Your prompt reply with any information would be deeply appreciated.

My specialty is in clinical medicine.  I will be pursuing a search of
the literature, if necessary in the days ahead, however, it would be
critically important to achieve confirmation as soon as possible.

Thank you,
