Did you know there are 2 types of avocado varieties? A-types switch from female to male, B-types male to female, within a single day. This reciprocal sex alternation promotes cross-pollination and has a simple genetic basis. Read more in this recent preprint from the final chapter of my PhD thesis 🥑

Balanced polymorphism in a floral transcription factor underlies an ancient rhythm of daily sex alternation in avocado

In avocado and certain wild relatives in Lauraceae, pollination occurs via a synchronized rhythm of floral sex timing between two hermaphroditic flowering types. A-type plants present female-phase flo...

Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.

Super proud of @alyssa-phillips.bsky.social 's paper, now out on biorxiv! She resolves the origin(s) of polyploid big blue-stem, a dominant species in the midwest tall-grass prairie. Her common garden analysis also informs on environmental adaptation and hints at the impacts of polyploidy.

The last work of my PhD is finally out: www.pnas.org/doi/10.1073/...! This work is about accurately estimating branch length in the Ancestral Recombination Graph (ARG), which is achieved by a really simple framework with minimal assumptions. (1/n)

Latest in #GENETICS: @petrelharp.bsky.social and the team show how non-coalescing haplotypes can be inserted into ancestral recombination graphs (ARGs), resulting in ARGs that are smaller, faster to compute with, and have additional ancestral information. buff.ly/X801LTO
