DOI: 10.1038/s41477-020-0725-0
Abstract: As a source of both energy and environmental information, monitoring of incoming light is crucial for plants to optimize growth throughout development 1 . Concordantly, the light signalling pathways in plants are highly integrated with… read more here.

DOI: 10.1104/pp.18.01244
Abstract: Two repressors of light signaling, BBX30 and BBX31, are transcriptionally and negatively regulated by the transcription factor HY5 through direct binding to the G-box cis-element present in their promoters. Light-mediated seedling development is coordinately controlled… read more here.

DOI: 10.1111/jipb.13329
Abstract: Arabidopsis CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) and PHYTOCHROME INTERACTING FACTORs (PIFs) are negative regulators, and ELONGATED HYPOCOTYL5 (HY5) is a positive regulator of seedling photomorphogenic development. Here, we report that SICKLE (SIC), a proline rich protein, acts… read more here.

DOI: 10.1111/php.13459
Abstract: Considering previously reported action spectra and molecular evidence, I propose a hypothetical model for UV RESISTANCE LOCUS8 (UVR8)‐mediated photomorphogenesis. Upon UV‐B irradiation, a UVR8 dimer dissociates and accumulates in the nucleus and photomorphogenesis begins following… read more here.

DOI: 10.3390/ijms23116027
Abstract: Photosynthetic pigments in higher plants, including chlorophyll and carotenoid, are crucial for photosynthesis and photoprotection. Previous studies have shown that nitric oxide (NO) plays a dual role in plant photosynthesis. However, how pigment biosynthesis is… read more here.
