key stages of flower development in carnation (PRJCA052030)
Double-flower formation is a highly valued ornamental trait. To investigate the regulatory mechanisms underlying petal number variation in carnation, we conducted integrated sRNA and lncRNA analyses using the single-flower cultivar 'MH' and the double-flower cultivar 'X4' of Dianthus chinensis at key stages of flower development. Based on the developmental stages of floral primordium morphogenesis described in a previous study, three representative stages were selected for analysis: S1 (vegetative growth stage), S3 (petal primordium development stage), and S5 (carpel development stage)(Zhang et al., 2024).
