The developmental gene Knotted-1 is a member of a maize homeobox gene family
THE Knotted-1 (Kn1) locus is defined by several dominant gain-of-function mutations that alter leaf development. Foci of cells along the lateral veins do not differentiate properly, but continue toExpand

Homologies in Leaf Form Inferred from KNOXI Gene Expression During Development
KNOTTEDI-like homeobox (KNOXI) genes regulate development of the leaf from the shoot apical meristem (SAM) and may regulate leaf form. We examined KNOXI expression in SAMs of various vascular plantsExpand

Developmental Changes Due to Long-Distance Movement of a Homeobox Fusion Transcript in Tomato
Long-distance movement of RNA through the phloem is known to occur, but the functional importance of these transported RNAs has remained unclear. Grafting experiments with a naturally occurringExpand

Overexpression of the maize homeo box gene, KNOTTED-1, causes a switch from determinate to indeterminate cell fates.
The KNOTTED-1 (KN1) locus of maize is defined by dominant mutations that affect leaf cell fates. Transposon tagging led to the isolation of the gene and the discovery that KN1 encodes a homeo domain.Expand

Auxin patterns Solanum lycopersicum leaf morphogenesis
One of the most striking aspects of plant diversity is variation in leaf shape. Much of this diversity is achieved by the modulation of leaf blade dissection to form lobes or leaflets. Here, we showExpand

A Quantitative Genetic Basis for Leaf Morphology in a Set of Precisely Defined Tomato Introgression Lines[C][W][OPEN]
Natural variation leading to differences in leaf morphology between domesticated tomato and a wild relative is explored in a set of introgression lines. The phenotypic context of leaf morphology withExpand

Natural Variation in Leaf Morphology Results from Mutation of a Novel KNOX Gene
Striking diversity in size, arrangement, and complexity of leaves can sometimes be seen in closely related species. One such variation is found between wild tomato species collected by Charles DarwinExpand

The genome of the stress-tolerant wild tomato species Solanum pennellii
Solanum pennellii is a wild tomato species endemic to Andean regions in South America, where it has evolved to thrive in arid habitats. Because of its extreme stress tolerance and unusual morphology,Expand

The expression domain of PHANTASTICA determines leaflet placement in compound leaves
Diverse leaf forms in nature can be categorized as simple or compound. Simple leaves, such as those of petunia, have a single unit of blade, whereas compound leaves, such as those of tomato, haveExpand

Compound Leaf Development and Evolution in the Legumes[W]
Across vascular plants, Class 1 KNOTTED1-like (KNOX1) genes appear to play a critical role in the development of compound leaves. An exception to this trend is found in the Fabaceae, where pea (PisumExpand
