Assessing the relative contributions of different Arabidopsis thaliana stigma factors to pollen hydration.

Abstract excerpt

Following pollination, Arabidopsis pollen grains rapidly hydrate through the transfer of water from the stigma to the pollen. Several stigma regulators of pollen hydration have been identified, and the corresponding mutants generally support milder defects in wildtype Col-0 pollen hydration, signifying the involvement of other unidentified factors in this process. Here, we uncovered a role for the stigma-specific...
