Review: How floral meristem termination shapes flowers

Flowers come in a breathtaking variety of shapes and sizes. The structures making up a flower, called sepals, petals, stamens, and carpels, all derive from the tightly regulated differentiation of a pool of stem cells in the so-called floral meristem. Floral meristem termination (FMT) is a crucial stage…

CYCLOIDEA3 is targeted by disparate transcription factors in patterning flowers in Gerbera

Yunqing Yu Donald Danforth Plant Science Center Kellogg Lab SAINT LOUIS, MO 63132 United States of America yyu@danforthcenter.org Flowering plants have evolved enormous diversity and complexity of inflorescence architecture. One great model for studying complex inflorescence development and…

silky3 Is a Novel Transcriptional Regulator that Influences Multiple Flower Development Pathways in Maize

Fine Tuning Floral Morphology: MADS-Box Protein Complex Formation in Maize

Plant floral organ development is orchestrated by master regulatory genes that control the differentiation of meristem tissue. According to the ABC(DE) model of flower development (Bowman et al., 1989; nicely summarized by Irish, 2017), different floral organs form in concentric whorls (verticils) in…
