Q: We recently had an open house party here at our new home. We had a couple of neighbors, along with our family. Auntie G. says she really liked the desert willow tree that is planted in the backyard ...

Scientists have determined how key developmental genes influence growth of cells to produce such differences in leaf form. The researchers were able to make thale cress, which typically produces ...

Different plants exhibit leaves with very diverse shapes, and scientists studying a carnivorous plant called Utricularia gibba (bladderwort) have learned how nature creates all the various leaf forms ...

An apple may not fall far from the tree, but for a leaf, it depends on its shape. Elm or apple leaves — oval and symmetrical, with few protruding lobes — fall quickly, making them likely to end up ...

The tropical butterfly Heliconius erato distinguishes between shapes, and uses them as a cue for choosing the plants on which to feed and lay eggs, shows new research by scientists from the University ...

The morphology of Salix herbacea leaves was examined to find possible reasons for the observed intraspecific morphological variation. Seventeen samples were collected from the following regions: the ...

Subtle changes in genetics can have major effects on how leaves grow into a wide variety of shapes. John Innes Centre Around the globe, plants have evolved to use their leaves for many purposes: broad ...

Variation in the size and shape (physiognomy) of leaves has long been correlated to climate, and paleobotanists have used these correlations to reconstruct paleoclimate. Most studies focus on ...
