Sieve-tube proteins from Cucurbita maxima

Planta, 1974
The two main proteins from the phloem exudate of Cucurbita maxima Duchesne have been isolated by ammonium-sulfate precipitation, DEAE-cellulose chromatography, and gel filtration, and have been characterized. They comprise about 40% each of the total protein. The amino-acid composition of these two proteins has been determined.

Antigenotoxic spinasterol from Cucurbita maxima flowers

Mutation Research/Environmental Mutagenesis and Related Subjects, 1996
The antigenotoxic constituent of squash flowers was isolated by solvent partitioning and repeated vacuum liquid chromatography. The micronucleus test, an in vivo method, was used to monitor the antigenotoxicity of the various fractions during the isolation process.

Different AT-rich satellite DNAs in Cucurbita pepo and Cucurbita maxima

Theoretical and Applied Genetics, 1986
The AT-rich highly repeated satellite DNA of Cucurbita pepo (zucchini) and Cucurbita maxima (pumpkin) were cloned and their DNA structure was investigated. DNA sequencing revealed that the repeat length of satellite DNA in Cucurbita pepo is 349-352 base pairs. The percentage of AT-base pairs is about 61%.

Metabolic networks of Cucurbita maxima phloem

Phytochemistry, 2003
Metabolomic analysis aims at a comprehensive characterization of biological samples. Yet, biologically meaningful interpretations are often limited by the poor spatial and temporal resolution of the acquired data sets. One way to remedy this is to limit the complexity of the cell types being studied. Cucurbita maxima Duch.

Ornithine transaminase from Cucurbita maxima cotyledons

Phytochemistry, 1973
Abstract During germination a marked increase in both soluble and particulate ornthine transaminase occurs in pumpkin cotyledons. Both enzymes had a pH optimum of 8.3 and a requirement for ornthine and α-ketoglutarate. Other keto acids or amino donors showed little activity.

KARAKTERISTIKE BUČA Cucurbita maxima

2015
U ovom istraživanju su korišteni uzorci dviju buča Cucurbita maxima (Hokkaido i Kabocha) čiji ekstrakti su pripremani u dvije akademske godine: 2014/2015. i 2013/2014. Prošlogodišnji uzorci bili su podvrgnuti ekstrakciji uz refluksiranje i ekstrakciji u ultrazvučnoj kupelji. Fenolni spojevi svih uzoraka buča određeni su pomoću Folin-Ciocalteu metode, a

Cucurbitacin 19-hydroxylase in Cucurbita maxima

Phytochemistry, 1978
Abstract The enzymatic hydroxylation of the C-19-methyl group of cucurbitacin B and D was observed in partly purified preparations obtained from the unripe fruit of Cucurbita maxima . Assay methods were developed and the pH optimum, cofactor requirements, and substrate specificity determined.

Phloemprotein bei Cucurbita maxima

Berichte der Deutschen Botanischen Gesellschaft, 1976
ZusammenfassungDie basischen P‐proteine von Cucurbita maxima zeigen Glucansynthetase‐Aktivität. Sie werden offensichtlich ständig in den Geleitzellen neu gebildet und notwendigerweise wieder abgebaut. Ein Zusammenhang zwischen Verstopfung der Siebporen mit P‐protein‐Filamenten und Callosebildung ist zu erkennen.
