Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL

open access: yesAngewandte Chemie, EarlyView.
Cyclic gallaphosphene 1 undergoes a twofold E─H bond activation with ammonia and water via a beneficial interplay between the polar “GaPGa” unit and the electrophilic nature of the C center in the bridging PCO unit, yielding six‐membered heterocycles 2 and 3, in which both nucleophilic phosphorus atoms are protonated.

Insights into organelle forming RNAs: Diversity, functions and future perspectives

open access: yesAnimal Models and Experimental Medicine, EarlyView.
RNA molecules play crucial roles in the formation and maintenance of cellular structures and organelles. These ‘organelle formation RNAs’ include ribosomal RNAs, paraspeckle‐forming RNAs, nuclear speckle‐forming RNAs, nucleolus‐forming RNAs, and cytoskeleton‐forming RNA.

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.
