Mol Biol Cell. 2004;15:3393-405 pubmed..We were able to demonstrate that TWD1 binds to isolated vacuoles and has a significant impact on the uptake of metolachlor-GS and estradiol-beta-glucuronide, well-known substrates of vacuolar transporters AtMRP1 and AtMRP2...
- Schonrock N, Bouveret R, Leroy O, Borghi L, Kohler C, Gruissem W, et al. Polycomb-group proteins repress the floral activator AGL19 in the FLC-independent vernalization pathway. Genes Dev. 2006;20:1667-78 pubmed..In this pathway, prolonged cold relieves AGL19 from PcG repression by a mechanism that requires VIN3 but not VRN2. Elevated AGL19 levels activate LFY and AP1 and eventually cause flowering. ..

Science. 2007;317:656-60 pubmed..Our findings show that the female control of pollen tube reception is based on a FER-dependent signaling pathway, which may play a role in reproductive isolation barriers. ..
