The presence of competing plants in the physical proximity is perceived in terms of reducing the proportion of red light (R, English network) and far-red (FR, far-red English), or ratio R: FR, the incident radiation. Anticipating shaded by other plants, the perception of low light ratio R: FR, conducted by the photoreceptor phytochrome, launches the so-called syndrome escape from the shadow "(SAS, its acronym in English), a stimulating set of responses, including the longitudinal growth at the expense of the accumulation of photoassimilates in harvestable organs, or bloom.
At the molecular level, the implementation of SAS induces rapid changes in gene expression. In this work, coordinated by Professor Martinez-Garcia, has addressed
