Sucrose content is a highly desirable trait in sugarcane as the worldwide demand for cost-effective biofuels surges. Sugarcane cultivars differ in their capacity to accumulate sucrose and breeding programs routinely perform crosses to identify genotypes able to produce more sucrose. Sucrose content in the mature internodes reach around 20% of the culms dry(More)
Sugarcane is generally propagated by cuttings of the stalk containing one or more lateral buds, which will develop into a new plant. The transition from the dormant into the active stage constitutes a complex phenomenon characterized by changes in accumulation of phytohormones and several other physiological aspects. Abscisic acid (ABA) and methyl-jasmonate(More)
A collection of 237,954 sugarcane ESTs was examined in search of signal transduction genes. Over 3500 components involved in several aspects of signal transduction, transcription, development, cell cycle, stress responses and pathogen interaction were compiled into the Sugarcane Signal Transduction (SUCAST) Catalogue. Sequence comparisons and protein domain(More)
Sucrose is the major product of photosynthesis in many higher plants. It is transported from the source tissue through the phloem to various sink tissues to support plant growth, development and reproduction. Knowledge on the signal transduction pathways involved in sucrose synthesis in mature leaves is limited. Using a microarray approach, we analyzed the(More)
The present article reports on the characterization of ScBAK1, a leucine-rich repeat receptor-like kinase from sugarcane (Saccharum spp.), expressed predominantly in bundle-sheath cells of the mature leaf and potentially involved in cellular signaling cascades mediated by high levels of sugar in this organ. In this report, it was shown that the ScBAK1(More)
