Sepal
Definition:
(n.) A leaf or division of the calyx.
Example Sentences:
(1) In agamous-1, stamens to petals; in apetala2-1, sepals to leaves and petals to staminoid petals; in apetala3-1, petals to sepals and stamens to carpels; in pistillata-1, petals to sepals.

(3) Sepal primordia then arise (stage 3) and grow to overlie the primordium (stage 4).
(4) In the families of flowering plants in which these organs occur, they are patterned with the sepals in the outermost whorl or whorls of the flower, with the petals next closest to the center, the stamens even closer to the center, and the carpels central.
(5) In flowers, expression was observed in sepals, anthers, and carpels, but not in petals.
(6) LAT52 mRNA is not detectable in pistils, sepals or non-reproductive tissues.
(7) Mutation of this gene (defA-1) causes homeotic transformation of petals into sepals and of stamina into carpels in flowers displaying the 'globifera' phenotype, as shown by cross sections and scanning electronmicroscopy of developing flowers.
(8) In ag mutants, the loss of AG function leads to the conversion of these organs to the perianth organs (petals and sepals).
