Knotted1-like homeobox (KNOX) proteins are homeodomain transcription factors that
maintain an important pluripotent cell population called the shoot apical meristem, which …

The development of plant leaves follows a common basic program that is flexible and is
adjusted according to species, developmental stage and environmental circumstances …

The full complement of homeobox transcription factor sequences, including genes and
pseudogenes, was determined from the analysis of 10 complete genomes from flowering …

Leaf shape is spectacularly diverse. As a major component of plant architecture and an
interface for light capture, gas exchange, and thermoregulation, the potential contributions of …

Tomato (Solanum lycopersicum) is one of the most important vegetable plants in the world. It
originated in western South America, and domestication is thought to have occurred in …

The leaves of seed plants evolved from a primitive shoot system and are generated as
determinate dorsiventral appendages at the flanks of radial indeterminate shoots. The …

The colonization and radiation of multicellular plants on land that started over 470 Ma was
one of the defining events in the history of this planet. For the first time, large amounts of …

Introgression lines (ILs), in which genetic material from wild tomato species is introgressed
into a domesticated background, have been used extensively in tomato (Solanum …

Neofunctionalization following gene duplication is thought to be one of the key drivers in
generating evolutionary novelty. A gene duplication in a common ancestor of land plants …

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 …
