Isolation, characterization and antitumour properties of the 1,2-propylenediaminetetraacetate-trans-diaqua-copper(II)
(Hindawi Publishing Corporation, 2000)
A trans-diaquacomplex formed by copper(II) sulphate and the sequestering polyamminopolycarboxylic ligand 1,2-propylenediaminetetraacetic acid (PDTA) has been isolated and characterized by chemical analysis, titrimetry, ...

A purL mutant of Sinorhizobium fredii HH103 is symbiotically defective and altered in its lipopolysaccharide
(Microbiology Society, 2003)
The pleiotropic phenotype of an auxotrophic purL mutant (SVQ295) of Sinorhizobium fredii HH103 has been investigated. SVQ295 forms colonies that are translucent, produce more slime and absorb less Congo red than those ...

A gibberellin-induced nuclease is localized in the nucleus of wheat aleurone cells undergoing programmed cell death
(The American Society for Biochemistry and Molecular Biology, 2003)
The aleurone layer of cereal grains undergoes a gibberellin-regulated process of programmed cell death (PCD) following germination. We have applied a combination of ultrastructural and biochemical approaches to analyze ...

Ultrastructure of the early stages of Colletotrichum acutatum infection of strawberry tissues
(National Research Council of Canada, 2005)
The early stages of the infection of attached leaves and petioles of strawberry (Fragaria ×ananassa Duch. ‘Camarosa’) by Colletotrichum acutatum Simmonds were studied using scanning and transmission electron microscopy. ...

A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes
(Sociedad Española de Microbiología. Viguera Editores, 2007)
Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media. The mutated gene, pyrF, codes for an ...

Development of Colletotrichum acutatum in the Foliar Tissue of Strawberry Plants
(Czech Academy of Agricultural Sciences, 2002)
Strawberry anthracnose, caused by Colletotrichum acutatum, is one of the most destructive disease of this crop throughout the world. Assymptomatic stages in the plant have been the aim of this work. Inoculated leaves ...

Characterization of infection and colonization of strawberry crowns by colletotrichum acutatum
(International Society for Horticultural Science, 2009)
Strawberry anthracnose, caused by Colletotrichum acutatum J.H. Simmonds, is one of the most important diseases of this crop in Huelva (southwestern Spain). Lesions can occur on all parts of the plant but anthracnose crown ...
