What is the influence of ordinary epidermal cells and stomata on the leaf plasticity of coffee plants grown under full-sun and shady conditions?

Pompelli, M. F.; Martins, S. C. V.; Celin, E. F.; Ventrella, M. C.; DaMatta, F. M. (Instituto Internacional de Ecologia, 2010)

Stomata are crucial in land plant productivity and survival. In general, with lower irradiance, stomatal and epidermal cell frequency per unit leaf area decreases, whereas guard-cell length or width increases. Nevertheless, ...
Transformation of coffee (Coffea Arabica L. cv. Catimor) with the cry1ac gene by biolistic, without the use of markers

De Guglielmo-Cróquer, Z.; Altosaar, I.; Zaidi, M.; Menéndez-Yuffá, A. (Instituto Internacional de Ecologia, 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 ...
Reproductive performance of the mite brevipalpus phoenicis (Geijskes, 1939) on citrus and coffee, using life table parameters

Teodoro, A. V; Reis, P. R. (Instituto Internacional de Ecologia, 2006)
