Blue light receptor CRY1 regulates HSFA1d nuclear localization to promote plant thermotolerance. Cell Rep 2023; 42:113117. [PMID: 37703177 PMCID: PMC10591714 DOI: 10.1016/j.celrep.2023.113117] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 05/24/2023] [Accepted: 08/25/2023] [Indexed: 09/15/2023] Open
Abstract
Temperature increases as light intensity rises, but whether light signals can be directly linked to high temperature response in plants is unclear. Here, we find that light pre-treatment enables plants to survive better under high temperature, designated as light-induced thermotolerance (LIT). With short-term light treatment, plants induce light-signaling pathway genes and heat shock genes. Blue light photoreceptor cryptochrome 1 (CRY1) is required for LIT. We also find that CRY1 physically interacts with the heat shock transcription factor A1d (HsfA1d) and that HsfA1d is involved in thermotolerance under light treatment. Furthermore, CRY1 promotes HsfA1d nuclear localization through importin alpha 1 (IMPα1). Consistent with this, CRY1 shares more than half of the chromatin binding sites with HsfA1d. Mutation of CRY1 (cry1-304) diminishes a large number of HsfA1d binding sites that are shared with CRY1. We present a model where, by coupling light sensing to high-temperature stress, CRY1 confers thermotolerance in plants via HsfA1d.

Abstract
DNA-binding one zinc finger protein (Dof) is a plant-specific transcription factor involved in numerous biological processes. In the current study, the plausible mechanism underlying Dof domain-DNA interaction in wheat was investigated using extensive molecular dynamics (MD) simulations analysis. We depicted that one key residue Lys29, possessing the ability to disturb the interaction between Dof domain-DNA upon substitution to Arg29. Frequent conformational changes were observed in Lys29Arg (K29R)-DNA complex during the entire MD simulation period, which significantly altered the interactions, thereby indicating the importance of Lys29 in complex stability. Principal component analysis and free energy landscape results also suggested strong affinity between wild-type Dof domain and DNA due to restricted atomic movement. Our study not only substantiates the structural and mechanistic insights of Dof transcription factor but also provides new avenues toward employment of these key amino acid residues in genetic engineering for development of abiotic stress tolerance crop plant.

Abstract
Porcine epidemic diarrhea virus (PEDV) causes acute diarrhea, vomiting, dehydration, weight loss, and high mortality rate in neonatal piglets. Porcine epidemic diarrhea (PED) has been reported in Europe, America, and Asia including Thailand. The disease causes substantial losses to the swine industry in many countries. Presently, there is no effective PEDV vaccine available. In this study, we developed a plant-produced monoclonal antibody (mAb) 2C10 as a prophylactic candidate to prevent the PEDV infection. Recently, plant expression systems have gained interest as an alternative for the production of antibodies because of many advantages, such as low production cost, lack of human and animal pathogen, large scalability, etc. The 2C10 mAb was transiently expressed in Nicotiana benthamiana and lettuce using geminiviral vector. After purification by protein A affinity chromatography, the antibody was tested for the binding and neutralizing activity against PEDV. Our result showed that the plant produced 2C10 mAb can bind to the virus and also inhibit PEDV infection in vitro. These results show excellent potential for a plant-expressed 2C10 as a PEDV prophylaxis and a diagnostic for PEDV infection.

Abstract
Land plants possess the ability to sense and respond to far-red light (700-760 nm), which serves as an important environmental cue. Due to the nature of far-red light, it is not absorbed by chlorophyll and thus is enriched in canopy shade and will also penetrate deeper into soil than other visible wavelengths. Far-red light responses include regulation of seed germination, suppression of hypocotyl growth, induction of flowering and accumulation of anthocyanins, which depend on one member of the phytochrome photoreceptor family, phytochrome A (phyA). Here, we review the current understanding of the underlying molecular mechanisms of how plants sense far-red light through phyA and the physiological responses to this light quality. Light-activated phytochromes act on two primary pathways within the nucleus; suppression of the E3 ubiquitin ligase complex CUL4/DDB1COP1/SPA and inactivation of the PHYTOCHROME INTERACTING FACTOR (PIF) family of bHLH transcription factors. These pathways integrate with other signal transduction pathways, including phytohormones, for tissue and developmental stage specific responses. Unlike other phytochromes that mediate red-light responses, phyA is transported from the cytoplasm to the nucleus in far-red light by the shuttle proteins FAR-RED ELONGATED HYPOCOTYL 1 (FHY1) and FHY1-LIKE (FHL). However, additional mechanisms must exist that shift the action of phyA to far-red light; current hypotheses are discussed.

Mass Spectrometric Analyses Reveal a Central Role for Ubiquitylation in Remodeling the Arabidopsis Proteome during Photomorphogenesis. MOLECULAR PLANT 2017; 10:846-865. [PMID: 28461270 PMCID: PMC5695678 DOI: 10.1016/j.molp.2017.04.008] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2017] [Revised: 04/17/2017] [Accepted: 04/18/2017] [Indexed: 05/21/2023]
Abstract
The switch from skotomorphogenesis to photomorphogenesis is a key developmental transition in the life of seed plants. While much of the underpinning proteome remodeling is driven by light-induced changes in gene expression, the proteolytic removal of specific proteins by the ubiquitin-26S proteasome system is also likely paramount. Through mass spectrometric analysis of ubiquitylated proteins affinity-purified from etiolated Arabidopsis seedlings before and after red-light irradiation, we identified a number of influential proteins whose ubiquitylation status is modified during this switch. We observed a substantial enrichment for proteins involved in auxin, abscisic acid, ethylene, and brassinosteroid signaling, peroxisome function, disease resistance, protein phosphorylation and light perception, including the phytochrome (Phy) A and phototropin photoreceptors. Soon after red-light treatment, PhyA becomes the dominant ubiquitylated species, with ubiquitin attachment sites mapped to six lysines. A PhyA mutant protected from ubiquitin addition at these sites is substantially more stable in planta upon photoconversion to Pfr and is hyperactive in driving photomorphogenesis. However, light still stimulates ubiquitylation and degradation of this mutant, implying that other attachment sites and/or proteolytic pathways exist. Collectively, we expand the catalog of ubiquitylation targets in Arabidopsis and show that this post-translational modification is central to the rewiring of plants for photoautotrophic growth.

Abstract
Phytochromes are red light (R) and far-red light (FR) receptors that play important roles in many aspects of plant growth and development. Phytochromes mainly function in the nucleus and regulate sets of genes by inhibiting negatively acting basic helix-loop-helix transcription factors named PHYTOCHROME INTERACTING FACTORs (PIFs) in Arabidopsis thaliana Although R/FR photoreversible responses and phytochrome genes are well documented in diverse lineages of plants, the extent to which phytochrome signaling is mediated by gene regulation beyond angiosperms remains largely unclear. Here, we show that the liverwort Marchantia polymorpha, an emerging model basal land plant, has only one phytochrome gene, Mp-PHY, and only one PIF gene, Mp-PIF These genes mediate typical low fluence responses, which are reversibly elicited by R and FR, and regulate gene expression. Mp-phy is light-stable and translocates into the nucleus upon irradiation with either R or FR, demonstrating that the single phytochrome Mp-phy exhibits combined biochemical and cell-biological characteristics of type I and type II phytochromes. Mp-phy photoreversibly regulates gemma germination and downstream gene expression by interacting with Mp-PIF and targeting it for degradation in an R-dependent manner. Our findings suggest that the molecular mechanisms for light-dependent transcriptional regulation mediated by PIF transcription factors were established early in land plant evolution.

Abstract
Phytochromes represent a diverse family of red/far-red-light absorbing chromoproteins which are widespread across plants, cyanobacteria, non-photosynthetic bacteria, and more. Phytochromes play key roles in regulating physiological activities in response to light, a critical element in the acclimatization to the environment. The discovery of prokaryotic phytochromes facilitated structural studies which deepened our understanding on the general mechanisms of phytochrome action. An extrapolation of this information to plant phytochromes is justified for universally conserved functional aspects, but it is also true that there are many aspects which are unique to plant phytochromes. Here I summarize some structural studies carried out to date on both prokaryotic and plant phytochromes. I also attempt to identify aspects which are common or unique to plant and prokaryotic phytochromes. Phytochrome themselves, as well as the downstream signaling pathway in plants are more complex than in their prokaryotic counterparts. Thus many structural and functional aspects of plant phytochrome remain unresolved.
