New fern genome just dropped! A haplotype resolved chromosome level assembly of Azolla caroliniana with the #CCGP @crothfels @fern_way @TribbleTweets biorxiv.org/content/10.1101/…

“The genome assembly of the duckweed fern, Azolla caroliniana”

Azolla is a genus of freshwater ferns that is economically important as a nitrogen-fixing biofertilizer, biofuel, bioremediator, and for potential carbon sequestration, but also contains weedy...

New paper alert (open access)! Thanks to a new tip-dated phylogeny of bonytongue fishes (Osteoglossomorpha) with a large sample of fossils, we find that today's freshwater arapaimas and arowanas were ancestrally marine! (1/n) royalsocietypublishing.org/d…

🌱From the upcoming #AJB #Polyploidy special issue🌱 The role of deep #hybridization in #fern speciation: Examples from the Thelypteridaceae By @fawcett_susan, @KuoFernLab, @YuHsinTseng1 and @tbisrael70 doi.org/10.1002/ajb2.16388 @wileyplantsci @WileyEcolEvol
Many examples of deep intergeneric hybridization have been documented among ferns -- however, these nearly always result in sterile progeny. This study provides evidence for several examples of allopolyploid speciation, in some cases between progenitor lineages estimated to have diverged up to 45 million years ago.

"childless woman" is such an 19th-century-ass insult. what else you got. do I render inferior tallow? do my cabbages grow pale and blemished? does the quality of my sock-darning bring shame upon my father's name?

Just baked! The impact of #genomesize on plant risk of #extinction. A huge collaborative effort led by @yam_it_up and @IliaLeitch. Always a pleasure to team up with such talented #scientists @KewScience @IBB_botanic nph.onlinelibrary.wiley.com/…

Genome size is positively correlated with extinction risk in herbaceous angiosperms

Angiosperms with large genomes experience nuclear-, cellular-, and organism-level constraints that may limit their phenotypic plasticity and ecological niche, which could increase their risk of ex...
