Overexpression of SHR enhance mesophyll cell division, resulting in a substantial reduction in leaf vein density. However, exogenous auxin treatments led to an increase in leaf vein density. Notably, ...

Indeterminate growth is a unique feature of plant development that is subject to intrinsic controls and modulated by environmental cues. Growth control is mediated by hormonal responses that rapidly ...

The endogenous indol-3yl-acetic acid (IAA) of detipped apical segments from roots of maize (cv ORLA) was greatly reduced by an exodiffusion technique which depended upon the preferential acropetal ...

Root hairs represent a low-cost strategy to enhance nutrient uptake because they can significantly increase the nutrient-acquiring surface of plant roots. While primary and lateral roots are ...

A gradient (red) in the concentration of auxin, a plant hormone, determines that only one of the eight undifferentiated nuclei in a plant's embryo sac will become an egg. (In this image, a large ...

A long-standing mystery surrounding a fundamental process in plant biology has been solved by a team of scientists at the University of California, Davis. The group's ground-breaking discovery that a ...

For most of the past century, scientists interested in plant growth and development generally fell into two different camps. Those interested in growth worked on plant hormones such as the small ...
