“…Genomic resources for the genus Salix are still under development, with the shrub willows being the most well-studied group with several assembled genomes and recent advances in QTL mapping of various traits, including yield, insect resistance, and rust susceptibility [22,23]. Within the section Vetrix, reference genomes are currently available for a female S. viminalis [24], a female S. suchowensis [25], a male S. purpurea ('Fish Creek'), a female S. purpurea (94006) [26], and a monoecious S. purpurea [11], the latter two of which have fully assembled Chr15Z and Chr15W sex chromosomes.…”
