Descripción
Biomass yield is a highly complex trait as it represents the combined outcome of many other complex traits, each under separate polygenic control. Poplars are usually grown for this purpose under short-rotation coppice (SRC) management with cutting back/coppicing of 3-5-year intervals. There is a need to identify traits and loci to produce enhanced SRC biomass-yielding genotypes. In poplars, one of these traits is sylleptic branching, that is the growth of lateral buds the same season in which they are formed without and intervening rest period. Sylleptic branching increases branch number, leaf area and the general growth of the tree in its early years, and also can be considered as a reasonable predictor of coppice yield. Our group have characterized the RAV1 gene of Castanea sativa (CsRAV1) encoding a transcription factor of the subfamily RAV (Related to ABI3/VP1). The constitutive expression of CsRAV1 in the hybrid clone Populus tremula x P. alba INRA 717 1B4 promotes the development of sylleptic branches a few weeks after potting, which make them promising candidates to improve biomass production (1). In 2012, we started a field trial to assess the performance of the transgenic poplars in outdoor long-term plantation. In this communication we will discuss the results obtained after one year of trial. (1) Moreno-Cortés et al. (2012). New Phytologist 194: 83-90
