Conteúdo:  Flesh fruit ripening is a complex developmental process that involves the formation of taste, aroma, establishment of skin color and fruit softening by cell wall hydrolysis. Physiological, biochemical and molecular evidences indicate that ethylene is the principal hormone controlling this developmental process. It exerts its action on several targets including its own biosynthesis, its perception by the target-cells via ethylene receptors (ETRs), a signal transduction network consisting of positive and negative regulators, and finally on the regulation of target-gene expression by transcription factors, such as ethylene response factors (ERFs) (STEPANOVA & ALONSO, 2009). In higher plant genomes, ERF is present as a superfamily of transcription factor genes defined by the presence of the APETALA2/ERF domain, a conserved DNA-binding sequence (NAKANO et al., 2006). In fruit species, ERFs are associated to flavor biosynthesis and texture modification during ripening (BAPAT et al., 2010). In the present work, we established a genetic framework for ERF and cell-wall proteins associated to the changes in fruit quality, texture and physiological post-harvest disorders in Malus using bioinformatic tools and comparative genomic approaches. The preliminary information obtained by in silico analyses is currently being validated by in vivo gene expression studies.

Título:  Plasticity in leaf-level water relations of tropical rainforest trees in response to experimental drought.
Ano de publicação:  2016

Conteúdo:  The tropics are predicted to become warmer and drier, and understanding the sensitivity of tree species to drought is important for characterizing the risk to forests of climate change. This study makes use of a long-term drought experiment in the Amazon rainforest to evaluate the role of leaf-level water relations, leaf anatomy and their plasticity in response to drought in six tree genera. The variables (osmotic potential at full turgor, turgor loss point, capacitance, elastic modulus, relative water content and saturated water content) were compared between seasons and between plots (control and through-fall exclusion) enabling a comparison between short- and long-term plasticity in traits. Leaf anatomical traits were correlated with water relation parameters to determine whether water relations differed among tissues. The key findings were: osmotic adjustment occurred in response to the long-term drought treatment; species resistant to drought stress showed less osmotic adjustment than drought-sensitive species; and water relation traits were correlated with tissue properties, especially the thickness of the abaxial epidermis and the spongy mesophyll. These findings demonstrate that cell-level water relation traits can acclimate to long-term water stress, and highlight the limitations of extrapolating the results of short-term studies to temporal scales associated with climate change.
