SPEECHLESS, SCREAM and stomata development in plant leaves

Plants constantly make trade-offs in their decisions: more light means more opportunity for photosynthesis, but then hot temperatures and dry air makes wilting more likely. Stomata—microscopic valves on the surface of a ...

Puzzling shapes: Unlocking the mysteries of plant cell morphology

The discovery of the mechanics and molecular mechanism that dictate cell shape formation in plants by a team of McGill researchers offers new clues about the fundamental processes governing tissue formation in multicellular ...

Location is everything for plant cell differentiation

While the fate of most human cells is determined by their lineage—for example, renal stem cells go on to form the kidney while cardiac progenitor cells form the heart—plant cells are a little more flexible. Research shows ...

Insect-deterring sorghum compounds may be eco-friendly pesticide

Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included ...

Rolling dice for cell size specification in plant leaf epidermis

One of the central questions in biology is how a cell specifies its size. Because size distribution often shows a characteristically skewed pattern in a tissue, there may be some stochastic option for determining cell size. ...

Random process may determine specialized cells in organs

What is the process that allows plant and animal organs to produce different specialized cells from an original set of identical cells? In the case of small and giant cells found in the sepals – the leaf-like covering of ...
