Endophytic bacteria in Coffea arabica L.
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, ...
متن کاملThidiazuron induced somatic embryogenesis in Coffea arabica L. and Coffea canephora P ex Fr
The rapid direct and repetitive somatic embryogenesis in Coffea arabica and C. canephora genotypes was tested on Murashige and Skoog medium (MS) containing thidiazuron (TDZ) (1-phenyl-3-(1,2,3,-thiadiazol-5-yl)urea) in concentrations of 2.27–11.35s M. Segments taken from cotyledon leaf, first leaf and stalk of regenerated plantlets produced clusters of somatic embryos directly from cut portions...
متن کاملDevelopment and validation of SSR markers for Coffea arabica L
With the objective of developing new SSR markers for Coffea arabica, two enriched genomic libraries with probes (GT)15 and (AGG)10 were constructed. A total of 835 clones were sequenced and 756 presented good quality sequences. Redundant sequences were observed for 113 clones (14.94%). SSRs were found in 287 clones (38%). An estimated size of 417.5Kb of the C. arabica genome was sampled, with a...
متن کاملEquine poisoning by coffee husk (Coffea arabica L.)
BACKGROUND In Brazil, coffee (Coffea arabica) husks are reused in several ways due to their abundance, including as stall bedding. However, field veterinarians have reported that horses become intoxicated after ingesting the coffee husks that are used as bedding. The objective of this study was to evaluate whether coffee husk consumption causes intoxication in horses. RESULTS Six horses fed c...
متن کاملStrategies to reconstruct 3D Coffea arabica L. plant structure
Accurate model of structural elements is necessary to model the foliage and fruit distributions in cultivated plants, both of them being key parameters for yield prediction. However, the level of details in architectural data collection could vary, simplifying the data collection when plants get older and because of the high time cost required. In the present study, we aimed at reconstructing a...
