The vascular cylinder is wide and has 7 or 8 radial, fan shaped bands of xylem alternating with parenchymatous, wide bands. The xylem bands have narrow, thick walled elements; phloem occurs only along ...

The crystal structure of the geranylgeranyl diphosphate synthase from Sinapis alba (mustard) has been solved in two crystal forms at 1.8 and 2.0 Å resolutions. In one of these forms, the dimeric ...

Functionally specialized leaves, flowers, and roots of vascular plants are integrated via stems to enable plant responses to changing environments (1). Plant stems provide essential mechanical support ...
