Fish were tested individually and given 24 hours to make a selection from four cover options, including rock, leaf pack, mussel shell, and an artificial cover unit. Among 30 trials, Carolina madtom preferred the artificial cover unit, selecting it 63% of the time. Rock was selected 23% of the time, and leaf pack 13%. Mussel shells were not selected during any trial.}, number={1}, journal={Journal of Freshwater Ecology}, publisher={Informa UK Limited}, author={Midway, S. R. and Aday, D. D. and Kwak, T.

The sucrose product was labeled only in the glucose moiety. Conversion of [(14)C]Gal-1-P to [(14)C]sucrose was catalyzed by extracts of peduncles from all other stachyose transporting species tested, as well as green bean (a sucrose transporter) but was not catalyzed by peduncle extracts from three other sucrose transporting species. In cucumber, the ability of extracts to form [(14)C]sucrose from [(14)C]Gal-1-P was greater when peduncles were harvested from growing fruit than from unpollinated ovaries. [(14)C]Sucrose formation from [(14)C]Gal-1-P was inhibited by Mg . PPi, Mg . UDP, UMP, and sucrose. alpha-Galactosidase, galactokinase, UDP-gal pyrophosphorylase, UDP-Gal-4'-epimerase, UDP-glucose pyrophosphorylase, and sucrose synthase activities were detected in peduncle extracts. Neither sucrose phosphate synthetase nor hexose-1-P uridyltransferase were detected. Peduncle tissue contained a small pool of free galactose. These results suggest a potential pathway for the metabolism of galactose moieties hydrolyzed from stachyose, the major sugar transported by cucumber plants.}, number={1}, journal={Plant Physiology}, author={Gross, K.

Abundant callus was produced on all of the above carbon sources. However, callus grew best on stachyose or raffinose after a substantial lag period (relative to growth on sucrose). Callus growth was similar on sucrose or galactose. α-Galactosidase activity was detected in hypocotyl explants and in calli grown on raffinose, melibiose, sucrose and galactose. Regardless of carbon source, cultured cells accumulated primarily sucrose, glucose and fructose internally. Free space sugars varied depending on carbon source and provided evidence of an extracellular location for α-galactosidase and invertase from cucumber cells.}, number={4}, journal={PLANT SCIENCE LETTERS}, author={GROSS, KC and PHARR, DM and LOCY, RD}, year={1981}, pages={333–341} }
