A red and far-red light receptor mutation confers resistance to the herbicide glyphosate
Glyphosate is a widely applied broad-spectrum systemic herbicide that inhibits competitively the penultimate enzyme 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) from the shikimate pathway, thereby causing deleterious effects. A glyphosate-resistant Arabidopsis mutant (gre1) was isolated and genetic analyses indicated that a dysfunctional red (R) and far-red (FR) light receptor, phytochro...
متن کاملAn Arabidopsis mutant hypersensitive to red and far-red light signals.
A new mutant called psi2 (for phytochrome signaling) was isolated by screening for elevated activity of a chlorophyll a/b binding protein-luciferase (CAB2-LUC) transgene in Arabidopsis. This mutant exhibited hypersensitive induction of CAB1, CAB2, and the small subunit of ribulose-1,5-bisphosphate carboxylase (RBCS) promoters in the very low fluence range of red light and a hypersensitive respo...
متن کاملEffect of Far-Red Light and its Interaction with Red Light in the Photoperiodic Response of Pharbitis nil.
Red light given in the inductive dark period inhibits flowering in short day plants, and this effect may be reversed by far-red light given shortly after the red irradiation. The pigment system involved in these reactions is called phytochrome. In Pharbitis, however, the flower-inhibitory effect of red light is not reversed by succeeding irradiation with far-red (6, 7, 8, 13). The flowering res...
متن کاملOccurrence of Far-Red Light Photoacclimation (FaRLiP) in Diverse Cyanobacteria
Cyanobacteria have evolved a number of acclimation strategies to sense and respond to changing nutrient and light conditions. Leptolyngbya sp. JSC-1 was recently shown to photoacclimate to far-red light by extensively remodeling its photosystem (PS) I, PS II and phycobilisome complexes, thereby gaining the ability to grow in far-red light. A 21-gene photosynthetic gene cluster (rfpA/B/C, apcA2/...
متن کاملEarly Stages in the Development of Plastid Fine Structure in Red and Far-red Light
Developmental changes in fine structure were studied in plastids of etiolated bean leaves during the time required for the protochlorophyllide-chlorophyllide transformation and the following lag phase prior to chlorophyll accumulation. In agreement with some other workers, two distinct stages of change in the fine structure of proplastids were found to occur upon illumination during this period...
