Cucurbita pepo tipo zucchini es una importante hortaliza en la región del Bajío; sin embargo, su producción esafectada por reducción de las poblaciones abejas polinizadoras y al efecto alteración ambiental sus hábitos reproductivos. Por lo cual, fundamental identificar genotipos partenocárpicos capaces generar frutos fecundación ni pérdida características agronómicas. El objetivo presente estud...

to those exhibited by xanthophyll cycle-dependent energy dissipation. The patterns of acclimation of The acclimation of photochemistry, xanthophyll cycleglutathione reductase are discussed in the context of dependent energy dissipation, and antioxidants was the multiple roles for reduced glutathione. Catalase characterized in leaves of Cucurbita pepo L. and Vinca acclimated in a manner consiste...

Plasmid pBG 35 contains the whole rDNA unit from flax (Linum usitatissimum L.) (Goldsbrough and Cullis, 1981). We cloned four different Eco RI restriction rDNA fragments of pBG 35 in the plasmid vector pBluescript SK+ (pBS). One of the subclones (p2.1) contained the most part of the 5 ́-end of 18S rRNA gene (1581 bp) and was used as a heterologous DNA probe in molecular hybridization experiments...

ORNITHINE: 2-oxoacid aminotransferase (EC 2.6.1.13) has been purified over 400-fold with a total recovery of 14% from acetone powders of cotyledons of germinating squash (Cucurbita pepo, L.) seedlings. The pH optimum of the transamination between l-ornithine and alpha-ketoglutarate is 8 and the Michaelis constants are 4.7 mm and 6.3 mm, respectively. The enzyme has a molecular weight of 48,000 ...

The ether phospholipid platelet-activating factor and certain similar phospholipids, including lysophosphatidylcholine, are known to stimulate both H(+) transport and protein phosphorylation in plant microsomal membranes. In the present work, several polypeptides in highly purified tonoplast membranes from zucchini (Cucurbita pepo L.) showed platelet-activating factor-dependent phosphorylation....
