Plants have evolved a delicate molecular system to fine-tune their growth and development in response dynamically changing light environments. In this study, we found that BBX28, B-box domain protein, negatively regulates photomorphogenic dose-dependent manner Arabidopsis thaliana. BBX28 interferes with the binding of transcription factor HY5 promoters its target genes through physical interactions, thereby repressing activity affecting HY5-regulated gene expression. darkness, associates...
Light-mediated seedling development is coordinately controlled by a variety of key regulators. Here, we identified two B-box (BBX)-containing proteins, BBX30 and BBX31, as repressors photomorphogenesis. ELONGATED HYPOCOTYL5, central regulator light signaling, directly binds to the G-box cis-element present in promoters BBX31 negatively controls their transcription levels light. Seedlings with mutations or are hypersensitive light, whereas overexpression leads hypo-photomorphogenic growth...
Light is one of the key environmental cues controlling photomorphogenic development in plants. A group B-box (BBX) proteins play critical roles this developmental process through diverse regulatory mechanisms. In study we report that BBX29 acts as a negative regulator light signaling. interacts with CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) and undergoes COP1-mediated degradation dark. Mutant seedlings loss function show shortened hypocotyls, while transgenic plants overexpressing display...
Abstract B-box containing proteins (BBXs) integrate light and various hormonal signals to regulate plant growth development. Here, we demonstrate that the photomorphogenic repressors BBX28 BBX29 positively brassinosteroid (BR) signaling in Arabidopsis thaliana seedlings. Treatment with BR brassinolide stabilized BBX29, which partially depended on INSENSITIVE1 (BRI1) BIN2. bbx28 bbx29 seedlings exhibited larger cotyledon aperture than wild-type when treated brassinazole dark, suppressed...
Abstract Intron retention (IR) is the most common alternative splicing event in Arabidopsis . An increasing number of studies have demonstrated major role IR gene expression regulation. The impacts on plant growth and development response to environments remain underexplored. Here, we found that functions directly regulation a genome-wide scale through detainment intron-retained transcripts (IRTs) nucleus. Nuclear-retained IRTs can be kept away from translation this mechanism. COP1-dependent...
Excessive alcohol consumption can lead to brain tissue damage and cognitive dysfunction. Acetaldehyde, the most toxic metabolite of ethanol, mediates dysfunction induced by chronic excessive consumption. In this study, effect astaxanthin, a marine bioactive compound, on acetaldehyde-induced cytotoxicity was investigated in SH-SY5Y cells. It found that astaxanthin protected cells from apoptosis ameliorating acetaldehyde expression Bcl-2 family proteins, preventing reduction anti-apoptotic...
We applied suppression subtractive hybridization and mirror orientation selection to compare gene expression profiles of isolated Nicotiana tabacum cv SR1 zygotes egg cells. Our results revealed that many differentially expressed genes in were transcribed de novo after fertilization. Some these are critical zygote polarity pattern formation during early embryogenesis. This suggests the transcriptome is restructed maternal-to-zygotic transition happens before first zygotic division, which...
Summary The maternal‐to‐zygotic transition (MZT) is characterized by the turnover of zygote development from maternal to zygotic control, and has been extensively studied in animals. A majority studies have suggested that early embryogenesis maternally controlled genome remains transcriptionally inactive prior MZT. However, little known about MZT higher plants, its timing impact remain uncharacterized. Here, we constructed cDNA libraries tobacco ( Nicotiana tabacum ) egg cells, zygotes...
Light plays a central role in plant growth and development, providing an energy source governing various aspects of morphology. Previous study showed that many polyadenylated full-length RNA molecules within the nucleus contain unspliced introns (post-transcriptionally spliced introns, PTS introns), which may play rapidly responding to changes environmental signals. However, mechanism underlying post-transcriptional regulation during initial light exposure young, etiolated seedlings remains...
ABSTRACT The role of a tetR transcriptional regulatory gene ( SAV7471 ) in avermectin production the Gram-positive soil bacterium Streptomyces avermitilis was investigated by deletion, complementation, and overexpression experiments. Gene deletion open reading frame resulted overproduction. also SAV7472-SAV7473 transcripts, which encode protein unknown function flavoprotein possibly involved pantothenate coenzyme A (CoA) metabolism. EMSAs footprinting assays showed that can bind to two...
Excessive alcohol consumption can lead to brain tissue damage and cognitive dysfunction. It has been shown that heavy drinking is associated with an earlier onset of neurodegenerative diseases such as Alzheimer's disease. Acetaldehyde, the most toxic metabolite ethanol, speculated mediate dysfunction induced by chronic excessive alcohol. However, exact mechanisms which acetaldehyde induces neurotoxicity are not totally understood. In this study, we investigated cytotoxic effects in SH-SY5Y...
Grafting is a prevalent horticultural technique that enhances crop yields and stress resilience; nevertheless, compatibility issues frequently constrain its efficacy. This research examined the physiological, hormonal, transcriptional factors regulating between litchi (Litchi chinensis Sonn.) cultivars Feizixiao (FZX) Ziniangxi (ZNX). The anatomical growth investigations demonstrated significant disparities compatible (FZX as scion ZNX rootstock) incompatible (ZNX FZX grafts, with latter...
Light-triggered transcriptome reprogramming is critical for promoting photomorphogenesis in Arabidopsis seedlings. Nonetheless, recent studies have shed light on the importance of alternative pre-mRNA splicing (AS) photomorphogenesis. The factors factor phytochrome signaling (SFPS) and reduced red-light responses cry1cry2 background1 (RRC1) are involved B (phyB) pathway promote by controlling light- clock-related genes. However, that serve as repressors phyB remain unreported. Here, we...
Litchi exhibits a large number of flowers, many flowering batches, and an inconsistent ratio male female frequently leading to low fruit-setting rate. Floral sexual differentiation is crucial phase in perennial trees ensure optimal fruit production. However, the mechanism behind floral remains unclear. The objective study was identify role auxin at transcriptional level. results showed that flowers treated with naphthalene acetic acid (NAA) significantly lower than control stage (M0/F0)....
