A study of the C₄ plant itchgrass (Rottboellia exaltata L.f.) grown under 100%, 60%, 25% and 2% sunlight revealed differences in the anatomy and cytology of the foliar mesophyll and vascular bundles ...
A plant’s vascular system is essential for maintaining stem structure, providing mechanical support, and for delivering resources to various plant organs. However, the structure and distribution of ...
Research by Assistant Professor Jacob S. Suissa at the University of Tennessee, Knoxville, is revealing complexity in how ferns have evolved. Instead of the vascular structure inside fern stems ...
Tissue localizations of cytosolic glutamine synthetase (GS1; EC 6.3.1.2), chloroplastic GS (GS2), and ferredoxin-dependent glutamate synthase (Fd-GOGAT; EC 1.4.7.1) in rice (Oryza sativa L.) leaf ...
Neurons and synapses follow a “use it or lose it” paradigm—regular nerve firing promotes survival as well as maintenance of the dendrite tree. A paper in last week's Neuron links neural activity and ...
