DICER-LIKE 1 and DICER-LIKE 3 redundantly act to promote flowering via repression of FLOWERING LOCUS C in Arabidopsis thaliana.

abstract：:In lytic cycle crosses with Red-Gam-lambda phage, particles were examined that had undergone an Int-mediated exchange. It was assumed that this exchange dimerized the circular lambda, making it packageable. Among these Int-mediated recombinants, particles were identified that had, in addition, enjoyed a close double e...

abstract：:Centromere H3 proteins (CenH3's) are variants of histone H3 specialized for packaging centromere DNA. Unlike canonical H3, which is among the most conserved of eukaryotic proteins, CenH3's are rapidly evolving, raising questions about orthology and conservation of function across species. To gain insight on CenH3 evol...
