recommendations! Published in 2020 at "Nature Plants"

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: 10.1073/pnas.2404883121

Abstract: Significance For the initial growth of seedlings, the transcription factor ELONGATED HYPOCOTYL5 (HY5) plays a critical role by initiating a series of light responses. Here, we demonstrated that besides transcription activity of HY5, the HY5… read more here.

DOI: 10.1093/plphys/kiae002

Abstract: Light induced de-etiolation is an important aspect of seedling photomorphogenesis. GOLDEN2 LIKE (GLK) transcriptional regulators are involved in chloroplast development, but to what extent they participate in photomorphogenesis is not clear. Here we show that… read more here.

DOI: 10.1093/plphys/kiae301

Abstract: ELONGATED HYPOCOTYL 5 (HY5) is a major light-associated transcription factor involved in plant growth and development. In Arabidopsis (Arabidopsis thaliana), the role of HY5 is very well-defined in regulating primary root growth and lateral root… 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/jipb.13719

Abstract: Dwarfing is a pivotal agronomic trait affecting both yield and quality. Citrus species exhibit substantial variation in plant height, among which internode length is a core element. However, the molecular mechanism governing internode elongation remains… 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.
