Effect of abscisic acid and cytokinins on cultured zygotic embryos of Coffea arabicacv.Cauvery (Catimor)

open access: yesPlant Cell, Tissue and Organ Culture, 2004
Immature zygotic embryos of Coffea arabica L.cv.Cauvery (Catimor) were sequentially cultured on different modifications of Murashige and Skoog's (MS) medium to test the effect of abscisic acid and cytokinins. The type of response depended on the medium strength, the growth regulator combinations as well as the period of initial culture in both abscisic

Transformation of coffee (Coffea Arabica L. cv. Catimor) with the cry1ac gene by biolistic, without the use of markers

open access: yesBrazilian Journal of Biology, 2010
The transformation of coffee plantlets with the cry1ac gene of Bacillus thuringiensis was achieved by biolistic using either the whole pUBC plasmid or only the ubi-cry1ac-nos genetic cassette. The cry1ac gene was inserted into coffee plants in order to confer resistance to the leaf miner Leucoptera coffeella, an insect responsible for considerable ...

Identification of race XXXIII of Hemileia vastatrix on Coffea arabica Catimor derivatives in Brazil [PDF]

open access: yesAustralasian Plant Disease Notes, 2012
In this study, a survey of physiological races of H. vastatrix was carried out on 64 coffee leaf rust samples from genotypes of Coffea arabica, C. canephora and Hibrido de Timor/Icatu derivatives that are cultivated in Brazil’s main production areas. Based on the infection pattern in a series of differentiating coffee tree clones, the races I, II, III ...

Comparative study of protein electrophoretic patterns during embryogenesis in Coffea arabica cv Catimor

Plant Cell Reports, 1994
Embryogenic and non-embryogenic calli from leaf sections of Coffea arabica cv. Catimor, were analyzed under denaturing conditions in one- and two-dimensions by polyacrylamide gel electrophoresis. The protein patterns revealed qualitative and quantitative differences in size and charge.

Morphogenic events during indirect somatic embryogenesis in coffee ?Catimor?

Protoplasma, 1997
The main goal of this research was to identify and describe the morphological and histological events during coffee somatic embryogenesis. Leaf sections of coffee “Catimor” (Coffea arabica CV. Red Caturra X hybrid of Timor) were cultivated in vitro on solid medium containing 2,4-dichlorophenoxyacetic acid and benzyladenine.
