Temperature and photoperiod changes affect cucumber sex expression by different epigenetic regulations

open access: yesBMC Plant Biology, 2018
Background Cucumbers (Cucumis sativus) are known for their plasticity in sex expression. DNA methylation status determines gene activity but is susceptible to environmental condition changes. Thus, DNA methylation-based epigenetic regulation may at least
