Proc Natl Acad Sci U S A. 2014;111:8547-52 pubmed publisher..Our results reveal an important, previously unidentified function of DDM1 and MOM1 in rapid resetting of stress induced epigenetic states, and therefore also in preventing their mitotic propagation and transgenerational inheritance. ..
- Malinova I, Mahlow S, Alseekh S, Orawetz T, Fernie A, Baumann O, et al. Double knockout mutants of Arabidopsis grown under normal conditions reveal that the plastidial phosphorylase isozyme participates in transitory starch metabolism. Plant Physiol. 2014;164:907-21 pubmed publisher..In continuous light, growth of both double mutants is similar to that of the parental single knockout lines. Metabolite profiles and oligoglucan patterns differ largely in the two double mutants. ..

Plant Cell. 2013;25:2560-72 pubmed publisher..Our in vivo data show that the size and position of this loop, determined by the choice of CArG element usage, is essential for correct expression. Our studies provide solid in vivo evidence for the floral quartet model. ..
