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)

Efficient near telomere-to-telomere assembly of Nanopore Simplex reads
Telomere-to-telomere (T2T) assembly is the ultimate goal for de novo genome assembly. Existing algorithms capable of near T2T assembly all require Oxford Nanopore Technologies (ONT) ultra-long reads w...

(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...
