摘要
Dear Editor The regulation of nectar production is dependent on hormonal signaling. For example, Arabidopsis PIN6, which encodes an auxin efflux transporter family protein, was identified as a nectary-enriched gene whose expression level was positively correlated to total nectar production （Bender et al., 2013）. Furthermore, jasmonic acid （JA） levels peak in Brassica flowers just prior to anthesis and promote nectar secretion （Radhika et al., 2010）. While auxin and JA have been demonstrated to play roles in the regulation of nectar production,
