Sixteen common bean genotypes, commercial varieties and advanced lines, were assessed at the Nucleus of Agrarian Sciences at the Federal University of Mato Grosso do Sul, Dourados campus, in the 'dry' harvest 2000/2001. Genetic and phenotypic parameters in control of morpho-physiological traits and yield components were estimated. These parameters were estimated at plant level. Variance estimates between and within genotypes and at plot level were obtained in randomized complete block experiments. Three replicates of each genotype were available for the calculations. The populations under study had wide genetic variability for all the traits studied whereas the main stem length was the most promising trait for selection and days to maturity was the least promising. The plot level analysis showed greater precision than plant level analysis. |

Conteúdo: |
ncreased synthesis of galactinol and raffinose family oligosaccharides (RFOs) has been reported in vegetative tissues in response to a range of abiotic stresses. In this work, we evaluated the transcriptional profile of a Coffea canephora galactinol synthase gene (CcGolS1) in two clones that differed in tolerance to water deficit in order to assess the contribution of this gene to drought tolerance. The expression of CcGolS1 in leaves was differentially regulated by water deficit, depending on the intensity of stress and the genotype. In clone 109A (drought-susceptible), the abundance of CcGolS1 transcripts decreased upon exposure to drought, reaching minimum values during recovery from severe water deficit and stress. In contrast, CcGolS1 gene expression in clone 14 (drought-tolerant) was stimulated by water deficit. Changes in galactinol and RFO content did not correlate with variation in the steady-state transcript level. However, the magnitude of increase in RFO accumulation was higher in the tolerant cultivar, mainly under severe water deficit. The finding that the drought-tolerant coffee clone showed enhanced accumulation of CcGolS1 transcripts and RFOs under water deficit suggests the possibility of using this gene to improve drought tolerance in this important crop. |
