From: The pennycress (Thlaspi arvense L.) nectary: structural and transcriptomic characterization
Pennycress genes likely involved in nectar synthesis and secretion. The primary steps of nectar production in Arabidopsis are â‘ starch degradation, â‘¡ sucrose biosynthesis, â‘¢
sucrose export via SWEET9, and ④ extracellular hydrolysis by CELL WALL INVERTASE4. Putative pennycress orthologs to these genes, or representative enzymes involved in each of these steps, were identified from RNA-seq-derived contigs. The gene abbreviation, gene number, and expression ratio between mature and immature nectaries are listed (Mat/Imm). BAM, β-amylase; SUS, sucrose synthase. Each of these loci were significantly (p < 0.05) more highly expressed in mature over immature nectaries
