The ion relations of isolated mesophyll cells from Antirrhinum leaf tissue were compared with the corresponding properties of the freshly excised leaf tissue. Both systems showed active influxes of K+ ...

Randy Moore and Clanton C. Black, Jr. Nitrogen assimilation in crabgrass Digitaria sanguinalis (L.) Scop., was studied by comparing leaf extracts with isolated mesophyll cell and bundle sheath strand ...

Little is known about the developmental control of leaf size and shape, and understanding the mechanisms behind this is a major issue in plant biology. New research concludes that communication ...

IN a recent communication 1, it was recorded that a number of hydrocarbons, including pure paraffin, readily entered the air-spaces of a leaf strip placed vertically in contact with the surface of ...

Ever looked carefully at the leaves on a plant and noticed their various sizes and shapes? Why are they different? What controls the size and shape of each individual leaf? Very little is known about ...
