A Role for Plant LINC Complexes in Male Fertility and Stomatal Function

Explore a cell plenary talk from the SEB Annual Conference 2021 focusing on the role of plant LINC complexes in male fertility and stomatal function. Delve into the structure and function of the nuclear envelope, with emphasis on the WIP/WIT LINC complex and its involvement in male fertility. Examine nuclear movement in germinating pollen and defects in pollen tube termination. Investigate the roles of KASH proteins SINE1 and SINE2 in stomatal closure, including the effects of actin-modifying drugs. Gain insights into the differential functions of these proteins during stomatal closure, as presented by Iris Meier from Ohio State University in this 51-minute lecture.
