The roads most traveled: genetic convergence in plant repeated evolution
New Phytologist, EarlyView.Observation of a genotype–phenotype association in a focal lineage (magnifying lens) provides a starting point for predicting homolog reuse during repeated trait evolution. This review suggests that the likelihood that mutations in homologous genes contribute to similar phenotypes in other lineages depends on both mutational effect stability (MES) and ...

Plant Direct, 2020 The constitutively active missense allele of Arabidopsis phytochrome B, AtPHYBY276H or AtYHB, encodes a polypeptide that adopts a light‐insensitive, physiologically active conformation capable of sustaining photomorphogenesis in darkness.

Cytoplasmic Phytochrome Action [PDF]
Plant and Cell Physiology, 2010 Phytochrome photoperception is a common mechanism for the detection of red and far-red light in bacteria, cyanobacteria, fungi and plants. However, the responses following phytochrome activation appear to be quite diverse between species. Lower plants, such as mosses, show phytochrome-mediated directional responses, namely phototropism and ...

New Phytologist, EarlyView.Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...

Frontiers in Plant Science, 2016 Plant seedlings germinating under the soil are challenged by rough soil grains that can induce physical damage and sudden exposure to light, which can induce photobleaching.

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk
Plant Biotechnology Journal, EarlyView.ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

Partial Proteolysis of Rice Phytochrome: Comparison with Oat Phytochrome
Zeitschrift für Naturforschung C, 1989 Phytochrome was isolated from etiolated rice seedlings (Oryza sativa L.) by slight modification of the procedure for oat phytochrome. Spectral data of rice phytochrome are comparable with those of oat and rye phytochrome. Controlled proteolysis with endoproteinases Lys-C and Glu-C yielded defined fragments some of which were different for Pr and Pfr ...

Plant, Cell &Environment, EarlyView.ABSTRACT Light is a primary environmental signal that induces plant anthocyanin accumulation. The plant growth regulator 5‐aminolevulinic acid (ALA) has also been proven to effectively promote anthocyanin accumulation in apple. However, the underlying regulatory mechanisms remain unknown.

PLoS ONE, 2014 PhyC levels have been observed to be markedly lower in phyB mutants than in Arabidopsis or rice wild type etiolated seedlings, but the mechanism of this phenomenon has not been fully elucidated.In the present study, we investigated the mechanism by which phyB affects the protein concentration and photo-sensing abilities of phyC and demonstrated that ...
