2020. Alternate expression of CONSTANS-LIKE 4 in short days and CONSTANS in long days facilitates day-neutral response in Rosa chinensis. Journal of Experimental Botany 71, 4057-4068 Day neutrality is an important agronomical trait in crop species such as rose (Rosa chinensis), a major cut-flower crop, allowing continuous flowering (CF) whatever the daylength. In Lu et al. (2020), the authors highlighted the role of the CONSTANS-LIKE 4 (RcCOL4) and CONSTANS (RcCO) proteins in the regulation of the florigen FLOWERING LOCUS T (RcFT) expression under long-day (LD) and short-day (SD) conditions, respectively. They further showed that RcCO binds to the CORE motif of the RcFT promoter and proposed a model in which RcCOL4 interacts with RcCO to enhance RcFT expression. Altogether, their results showed that RcCO and RcCOL4 contribute to day neutrality in CF rose.< Réduire
