We have recently gained insight into a number of mechanisms governing the formation of the major axes that define the embryonic and adult plant body plan. Phenotypic analysis and molecular characterization of mutants with aberrant morphogenesis has led to a better understanding of key processes including the generation of the shape of the apical embryo, the establishment and maintenance of the radial pattern of the root, and the placement of lateral organ primordia around the shoot apical meristem.
Variation among vascular plants in the initiation and patterning of leaves results in a diverse array of leaf shape, including the strap-like leaf of many grasses and the broad lamina of most eudicots. Recent findings highlight the importance of interactions between the shoot apical meristem (SAM) and developing leaf primordia in axis specification and the establishment of leaf shape. Global regulators of epigenetic states have been implicated in these interactions and may play a role in distinguishing founder cells and stem cells within the SAM.
During the past two years, significant progress has been made towards understanding the molecular basis of how multiple pathways regulating the floral transition are integrated. The transcriptional regulation of several genes, the floral meristem identity gene LEAFY and the 'flowering-time' genes FLOWERING LOCUS T and SUPPRESSOR OF OVEREXPRESSION OF CO 1 (also known as AGAMOUS-LIKE 20), is a point at which multiple pathways that promote flowering are integrated.
