Activities of the chloroplasts and nucleus are coordinated by retrograde signaling, which has crucial roles in plant development environmental adaptation. However, connection between chloroplast status nuclear genome stability is not well understood. Chloroplast state transitions allow to balance absorption capacity photosystems an environment light quality was changing. Here we demonstrate that abnormal lead instability impaired growth. We observed increased DNA damage transition-defective...
Maximizing light capture by light-harvesting pigment optimization represents an attractive but challenging strategy to improve photosynthetic efficiency. Here, we report that loss of a previously uncharacterized gene, HIGH PHOTOSYNTHETIC EFFICIENCY1 (HPE1), optimizes pigments, leading improved efficiency and biomass production. Arabidopsis (Arabidopsis thaliana) hpe1 mutants show faster electron transport increased contents carbohydrates. HPE1 encodes chloroplast protein containing RNA...
Abstract N 6 -methyladenosine (m A) modification of mRNAs affects many biological processes. However, the function m A in plant photosynthesis remains unknown. Here, we demonstrate that is crucial for during photodamage caused by high light stress plants. The levels numerous photosynthesis-related transcripts are changed after stress. We determine Arabidopsis writer VIRILIZER (VIR) positively regulates photosynthesis, as its genetic inactivation drastically lowers photosynthetic activity and...
Dendrobium officinale is edible and has medicinal ornamental functions. Polysaccharides flavonoids, including anthocyanins, are important components of D. that largely determine the nutritional quality consumer appeal. There a need to study molecular mechanisms regulating anthocyanin polysaccharide biosynthesis enhance its market value. Here, we report high light (HL) induced accumulation polysaccharides, particularly mannose, as well accumulation, resulting in red stems. Metabolome...
ABSTRACT Chloroplasts are key organelles for capturing solar energy and establishing plant immunity. During photosynthesis pathogen defense, highly redox‐active reactions take place in chloroplasts generate large amounts of reactive oxygen species (ROS). However, our knowledge chloroplast‐produced ROS biosynthesis immunity under varying light conditions is limited. Here, we report that the chloroplast‐localized protein HYPERSENSITIVE TO HIGH LIGHT 1 (HHL1) functions as a dual regulator...
The effects of calcium chloride solution (10 mmol L-1) on mesophyll cell ultrastructure, gas exchange, chlorophyll and carotenoid content, PSII in tobacco leaf were studied by simulating water deficit conditions via treatment with 25% PEG-6000 for 24 h. results showed that under drought stress, the structure morphology destroyed, photosynthesis gas-exchange processes changed, photosynthetic pigment content decreased, electron transfer efficiency reduced. However, compared control treatment,...
Significance Photosystem II (PSII) reaction center protein D1 is encoded by chloroplast gene psbA and crucial to the biogenesis functional maintenance of PSII. proteins are highly dynamic under varying light conditions thus require efficient synthesis, but mechanism remains poorly understood. We reported that Arabidopsis LPE1 directly binds 5′ UTR mRNA in a light-dependent manner through redox-based facilitates association HCF173 with regulate translation. These findings fill major gap our...
The coordination of chloroplast and nuclear genome status is critical for plant cell function. Here, we report that Arabidopsis CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains stability in the nucleus. CND1 localizes to both compartments, complete loss results embryo lethality. Partial disturbs cell-cycle progression photosynthetic activity. binds pre-replication complexes DNA replication origins regulates stability. In chloroplasts, interacts with facilitates binding...
Abstract The balance between cellular carbon (C) and nitrogen (N) must be tightly coordinated to sustain optimal growth development in plants. In chloroplasts, photosynthesis converts inorganic C organic C, which is important for maintenance of content plant cells. However, little known about the role chloroplasts C/N balance. Here, we identified a nuclear‐encoded protein LOW PHOTOSYNTHETIC EFFICIENCY2 (LPE2) that it required Arabidopsis . LPE2 specifically localized chloroplast. Both...
Nonphotochemical quenching (NPQ) is an important photoprotective mechanism that quickly dissipates excess light energy as heat. NPQ can be induced in a few seconds to several hours; most studies of this process have focused on the rapid induction NPQ. Recently, new, slowly form NPQ, called qH, was found during discovery inhibitor suppressor 1 (SOQ1). However, specific qH remains unclear. Here, we hypersensitive high (HHL1)-a damage repair factor photosystem II-interacts with SOQ1. The...
Optimizing central carbon metabolism (CCM) represents an attractive and challenging strategy to improve the biosynthesis of valuable chemicals due complex regulation CCM in yeast. In this study, we triggered similar Warburg effect cancer cells yeast strains by introducing human hypoxia-inducible factor-1 (HIF-1) complex, which regulated expression numerous enzymes involved redirected metabolic flux from glycolysis tricarboxylic acid cycle. This redirection promoted production squalene a...
Chloroplasts have their own genomes, as do the nucleus and mitochondria. Coordination between these genomic compartments in plant cells is crucial for development adaptation to environment. However, little attention has been paid coordination of genome stability chloroplast other compartments. Several recent studies shed light on regulatory mechanisms governing this coordination, demonstrating importance communication different genomes maintain stability. Here we review chloroplasts cells....
ABSTRACT Light is a vital environmental signal that regulates the expression of plastid genes. Plastids are crucial organelles respond to light, but effects light on RNA processing following transcription remain unclear. In this study, we systematically examined influence exposure processing, focusing splicing and editing. We demonstrated promotes transcripts from genes rps12 , ndhA atpF petB rpl2 . Additionally, increased editing rate accD transcript at nucleotide 794 ( accD‐ 794) ndhF 290...
