Development of virus-induced genome editing methods in Solanaceous crops.

Scientists developed two virus-induced genome editing (VIGE) methods for Solanaceous plants using TRV and PVX vectors. VIGE showed high mutation rates of 40.3% and 36.5%, and heat treatment increased editing efficiency by 33% to 76%. The methods can be applied to other Solanaceous crops.

Exploring ethylene-related genes in Cannabis sativa: implications for sexual plasticity.

Researchers identified expression patterns in ethylene-related genes (ERGs) associated with sexual determination in Cannabis sativa. They proposed a new pattern called karyotype concordant (KC) expression and found that ERGs related to sexual plasticity are widespread. This could inform regulation decisions for sexual plasticity in the plant.
