Plant protein complex plays large role in imp

While many plant cells contain one large vacuole, Marcela Rojas-Pierce wants to examine how, in some model plant Arabidopsis cells, vacuoles control the opening and closing of stomata - plant "pores" that must be regulated to balance carbon dioxide intake and the release of oxygen via water vapor.

"But this beautiful and elaborate system must be tightly regulated to properly ensure the plant's response to the environment.

"SNARE proteins actually do the job of vacuole fusion, but our study showed that the HOPS protein VPS41 may be a key player in the process, while HOPS protein VPS33 may act as a chaperone to guide vacuole fusion," Rojas-Pierce said.

Believed to be a kind of plant garbage dump, with multiple roles in storage and recycling, vacuoles are also critical for pollen development, with sterility the consequence if the process goes awry.
