Extracellular ATP is a known receptor agonist in animals and was previously shown to alter plant growth, and so we investigated whether ATP derivatives could function outside plant cells as signaling agents. Signaling responses induced by exogenous nucleotides in animal cells typically include increases in free cytoplasmic calcium concentration(More)
Materials for cell wall growth are delivered to the wall by secretory vesicles, and recent studies have highlighted the role of secretion in plant growth generally and plant gravitropic growth specifically. Funke and Edelmann (2000) show that the growth of graviresponding nodes of Tradescantia is controlled by auxin-induced secretion and subsequent(More)
Subscapularis nodules are rare causes of shoulder pain. There have been no reports of nodular swellings arising from the articular surface of the subscapularis tendon. We report two original cases of intra-articular subscapular nodules with reciprocal middle glenohumeral ligament thickening. In both cases, the patients had long standing deep-seated anterior(More)
