Representative genes and processes putatively involved in carbon flux in squash nectaries. (a) Expression of genes in male and female nectaries involved in each of the proposed steps of nectar synthesis and secretion as outlined in panel b; SBE = starch branching enzyme; BAM1 = beta‐amylase; SPS = sucrose‐phosphate synthase; SWEET9 = sucrose transporter; CWINV4 = cell wall invertase (c) Approximate timing of processes involved in nectar production based on data from this study and previously published reports
