It’s hard to believe our summer undergraduate researchers are wrapping up in just a few weeks! This summer of science has flown by. Catch up on their adventures in the lab, out in the field, around Ithaca, and beyond!

This seems to work really well! Improved a draft genome with N50=0.5 Mb (flye 2.9.4/hifiasm-0.19.8), increased to N50=5 Mb (11 Mb after removing all the repetitive element contigs)

(2/2) Giant sex chromosomes were discovered in Silene latifolia more than 100 years ago. Two papers back to back now show the sequence of the 550 Mbp Silene Y chromosome helping to understand sex determination

Rapid and dynamic evolution of a giant Y chromosome in Silene latifolia
Some plants have massive sex-linked regions. To test hypotheses about their evolution, we sequenced the genome of Silene latifolia, in which giant heteromorphic sex chromosomes were first discovered i...

Pan-phylum genomes of hornworts reveal conserved autosomes but dynamic accessory and sex chromosomes - Nature Plants
This study presents 11 new hornwort (Anthocerotophyta) genomes that clarify the structure and evolution of sex and accessory chromosomes in bryophytes and shed new light on the early evolution of land...
