Current Opinion in Plant Biology, 2001
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

Vascular patterning and leaf shape
Current Opinion in Plant Biology, 2001Morphogenesis of leaf shape and formation of the major elements of leaf vasculature are temporally coordinated during leaf development. Current analyses of mutant phenotypes provide strong support for the role of auxin signaling in vascular pattern formation and indicate that leaf shape and vasculature are developmentally coupled.

Shaping up: the genetic control of leaf shape
Current Opinion in Plant Biology, 2004Leaf initiation at the shoot apical meristem involves a balance between cell proliferation and commitment to make primordia. Several genes, such as CLAVATA1, CLAVATA3, WUSCHEL, KNOTTED1, and PHANTASTICA, play key roles in these processes. When expressed in the leaf primordium, however, these 'meristem' genes can profoundly affect leaf shape and size ...

Humans carry out object recognition as a very primitive task. However, knowing all the detailed information regarding an object is mostly not possible. Therefore, object recognition and linking the object to associated data is a popular research area. In this study, we have measured leaf recognition performances of different feature and data sets using

Science, 2003
The flat shape of most leaves enables them to capture sunlight for photosynthesis more efficiently. But how do leaves develop their flat shape? In their Perspective, [McConnell and Barton][1] discuss new work ([ Nath et al ][2].) that reveals how the differential expression of certain genes within developing leaves of the snapdragon makes these leaves ...

Current Opinion in Plant Biology, 2011
Leaves are formed from a group of initial cells within the meristem. One of the earliest markers of leaf initiation is the down-regulation of KNOX genes in initial cells. Polar auxin activity, MYB and LOB domain transcription factors function to keep KNOX out of the initiating leaf. If KNOX genes are expressed in initial cells, leaves fail to form.

MECHANISM OF LEAF-SHAPE DETERMINATION
Annual Review of Plant Biology, 2006Biodiversity of plant shape is mainly attributable to biodiversity of leaf shape and the shape of floral organs, the modified leaves. However, the exact mechanisms of leaf-shape determination remain unclear due to the complexity of flat-structure organogenesis that includes the simultaneous cell cycling and cell enlargement in primordia.

Fractal analysis of leaf shapes
Canadian Journal of Forest Research, 1986An application of fractal mathematics to the analysis of leaf shapes is presented. Six leaves randomly selected from nine tree species were used in the study. A video imaging method together with microcomputer-based image processing was used to generate leaf outlines.
