The disulfated peptide growth factor phytosulfokine-a (PSK-a) is perceived by LRR receptor kinases. In this study, a role for PSK signaling through PSK receptor PSKR1 in Arabidopsis thaliana hypocotyl cell elongation is established. Hypocotyls of etiolated pskr1-2 and pskr1-3 seedlings, but not of pskr2-1 seedlings were shorter than wt due to reduced cell(More)

OBJECTIVE To investigate the differences between skeletal and chronological age and to assess the role of maturity status, anthropometric data, and football related variables in explaining injury statistics in elite schoolboy footballers. DESIGN Prospective study of injuries in schoolboy footballers according to skeletal age. SETTING Premier league(More)
The bound carbohydrates of noncataractous , decapsulated, human lenses have been examined. The hexoses and hexosamines of the water-soluble, water-insoluble nonmembrane, and membrane fractions of lenses from six age groups were determined by gas-liquid chromatography. The plasma membrane contains 60-70% of all bound carbohydrates, including glucose,(More)
