Citrus plants have a long juvenile period, which has hampered the breeding progress of these species. In this sense, research focused on reducing the juvenile phase is needed to accelerate the breeding process. In this study, the morphology of the hybrid { [('Rangpur' lime) x YMCT ('Yuma' citrange) -005] x (Microcitrus papuana) -001} (H011), which has a short juvenile period, and the gene expression levels of the FLOWERING LOCUS T (FT) were evaluated. Morphological studies indicated early flowering and fruiting of the hybrid, characteristics that make it a promising candidate for citrus breeding. In addition, winter temperatures influenced the expression of the FT gene in stems and leaves.
Durante um estudo da diversidade de fungos em Orchidaceae, folhas e pseudobulbos de diferentes espécies de orquídeas foram coletados em seis municípios da Bahia, tendo a espécie fúngica Lasidioplodia theobromae sido encontrada associada a Cattleya, Phalaenopsis e Oncidium em dois dos seis municípios visitados. Por se tratar do primeiro registro de L. theobromae em orquídeas na Bahia, procurou-se estudar a interação fungo-hospedeiro por meio de inoculações artificiais, além de descrever e ilustrar a espécie fúngica.
Palavras-chave:Oncidium, Cattleya, Phalaenopsis, fungo Lasiodiplodia theobromae as an endophyte on orchidaceae in Bahia. During the study of the fungal diversity on Orchidaceae, leaves and pseudobulbs of different species of orchids were collected in six municipalities of Bahia and the fungus Lasiodiplodia theobromae was found associated with Cattleya, Phalaenopsis and Oncidium in two of the six visited municipalities. Since this was the first record of L. theobromae on orchids in Bahia, the fungus-host interaction was studied by means of artificial inoculations and the fungal species was described and illustrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
