An embryo-derived peptide signal directs endosperm polarity in Arabidopsis

Angiosperm seed formation requires the coordinated development of the products of double fertilization—the embryo and the endosperm. The endosperm mediates efficient nutrient transfer from surrounding...

I’m thrilled to share my latest research with @claudiakohler11.bsky.social in @mpi-mp-potsdam.bsky.social, now published in @natplants.nature.com ! In this work, we reveal that long-distance transported siRNAs from maternal sporophytic tissues are functional in pollen development and reproduction.

Nature Plants@natplants.nature.com · 9mo ago

New OA Article: "Long-distance transport of siRNAs with functional roles in pollen development" rdcu.be/e1pxk ...These mobile small RNAs support proper pollen development, revealing that non-cell-autonomous small RNAs are crucial for successful plant reproduction.

Registration is now open! The 4th edition of the Mendel Early Career Symposium will take place on 21-22 May at the GMI, part of the @viennabiocenter.bsky.social. This two-day event brings together researchers across career stages to discuss the latest research in all areas of plant science.

I am excited to offer a postdoctoral research position in my lab in Oxford studying the distribution of small RNAs during plant sexual reproduction. shorturl.at/7Goxt Reposts appreciated! Obligatory cat video to brighten your day. :-)
