Microsatellites for the genus Cucurbita and an SSR-based genetic linkage map of Cucurbita pepo L.

Metabolic Requirement of Cucurbita pepo for Boron.

Lateral roots of intact summer squash seedlings (Cucurbita pepo L.) were used to quantify the effects of boron deficiency on DNA synthesis, protein synthesis, and respiration. The temporal relationship between changes in these metabolic activities and the cessation of root elongation caused by boron deprivation was determined. Transferring 5-day-old squash seedlings to a hydroponic culture medi...

Distribution of a - Galactosidase in Cucurbita pepo

The distribution of a-galactosidase (a-D-galactoside galactohydrolase IEC 3.2.1.221) in Cucurbita pepo has been determined in an attempt to assess its involvement in hydrolysis of transport sugars of the raffinose oligosaccharide series (la-1-6-galactopyranosyllj sucrose). Extracts prepared from leaves and petioles at different stages of development, roots, flowers, dry and germinating seeds, a...

Cucumis SSR Markers Applied to the Study of Genetic Diversity in the Cucurbita Genus

The genus Cucurbita L. includes five cultivated species. C. pepo L., C. maxima Duchesne, and C. moschata Duchesne are the three most economically important. A high level of morphological and agronomical variability exists within these species. Large collections of Cucurbita landraces with a high potential value for breeding are maintained elsewhere. The COMAV’s Genebank at the Polytechnic Unive...

Recombination in the genus Cucurbita.

ARIOUS structural and physiological barriers to recombination in species Vhyb rids often impose rigorous limitations upon the extent to which the characters of one species may be combined with those of another. Among such barriers structural and genic imbalance resulting in the differential elimination of gametes and zygotes of recombination types has often been mentioned (ANDERSON 1939; DEMPST...
