Phytochrome E Plays a Role in the Suppression of Germination in Far-Red Light in Tomato.

ABSTRACT: As photoautotrophs, plants use light not only as a source of energy but also as cues for directing growth and development. Phytochromes comprise a small gene family of plant specific light receptors that absorb mostly in the red/far-red portion of the electromagnetic spectrum. These light receptors are well-studied in the model species Arabidopsis thaliana, yet much less is known about their functions in other species. We have generated CRISPR-induced mutations in SlPHYTOCHROME E (SlPHYE) and SlPHYF, produced higher order mutants, and characterized some of their physiological functions in tomato (Solanum lycopersicum). We report that SlphyE plays a major role in detecting far-red light, repressing germination when light conditions are unfavorable for esta
