Organelles are intracellular compartments which themselves compartmentalized. Biogenic and metabolic processes localized to specialized domains or microcompartments enhance their efficiency suppress deleterious side reactions. An example of intra-organellar compartmentalization is the pyrenoid in chloroplasts algae hornworts. This microcompartment enhances photosynthetic CO2-fixing activity Calvin-Benson cycle enzyme Rubisco, suppresses an energetically wasteful oxygenase mitigates limiting...
Photosynthesis is the energetic basis for most life on Earth, and in plants it operates inside double membrane–bound organelles called chloroplasts. The photosynthetic apparatus comprises numerous proteins encoded by nuclear organellar genomes. Maintenance of this requires action internal chloroplast proteases, but a role nucleocytosolic ubiquitin-proteasome system (UPS) was not expected, owing to barrier presented double-membrane envelope. Here, we show that photosynthesis (including those...
Abstract Background Hybridization and backcrossing are commonly used in animal plant breeding to induce heritable variation including epigenetic changes such as paramutation. However, the molecular basis for hybrid-induced memory remains elusive. Results Here, we report that hybridization between inbred parents B73 Mo17 induces trans -acting hypermethylation hypomethylation at thousands of loci; several hundreds (~ 3%) transmitted through six three selfing generations. Notably, many...
Summary Heterotrimeric G protein knock‐out mutants have no phenotypic defect in chloroplast development, and the connection between signaling pathway development has only been inferred from pharmaceutical evidence. Thus, whether plays a role remains an open question. Here, we present genetic evidence, using leaf‐variegated mutant thylakoid formation 1 ( thf1 ), indicating that inactivation or activation of endogenous α‐subunit (GPA1) affects as does ectopic expression constitutively active...
Maturation of chloroplast ribosomal RNAs (rRNAs) comprises several endoribonucleolytic and exoribonucleolytic processing steps. However, little is known about the specific enzymes involved cleavage steps they catalyze. Here, we report functional characterization single Arabidopsis (Arabidopsis thaliana) gene encoding a putative YbeY endoribonuclease. AtYbeY null mutants are seedling lethal, indicating that function essential for plant growth. Knockdown plants display slow growth show...
The cyanidin (Cy), pelargonidin (Pg) and delphinidin (Dp) pathways are the three major branching anthocyanin biosynthesis that regulate flavonoid metabolic flux responsible for red, orange blue flower colors, respectively. Different species have evolved to develop multiple regulation mechanisms form branched pathways. In current study, five Senecio cruentus cultivars with different colors were investigated. We found white yellow do not accumulate blue, pink carmine mainly Dp, Pg Cy in...
A small genome in chloroplasts encodes many of the polypeptide subunits photosynthetic electron transport complexes embedded membranes thylakoid vesicles chloroplast stroma and synthesized by ribosomes bacterial-like genetic system this semiautonomous organelle. While are sites translation, evidence unicellular alga Chlamydomonas reinhardtii supports translation on non-canonical a discrete translation-zone chloroplast. To characterize membranous platforms for biogenesis membranes, we...
A cDNA encoding the 180-kD canine ribosome receptor (RRp) was cloned and sequenced. The deduced primary structure indicates three distinct domains: an NH2-terminal stretch of 28 uncharged amino acids representing membrane anchor, a basic region (pI = 10.74) comprising remainder half acidic COOH-terminal 4.99). most striking feature acid sequence is 10-amino consensus motif, NQGKKAEGAP, repeated 54 times in tandem without interruption positively charged region. We postulate that this...
Intracellular processes can be localized for efficiency or regulation. For example, mRNA translation by chloroplastic ribosomes occurs in the biogenesis of PSII, one two photosystems photosynthetic electron transport chain chloroplasts plants and algae. The PSI PSII requires synthesis assembly their constituent polypeptide subunits, pigments, cofactors. Although these biosynthetic pathways are well characterized, less is known about when where they occur developing chloroplasts. Here, we...
Abstract The localization of translation can direct the polypeptide product to proper intracellular compartment. Our results reveal by cytosolic ribosomes on a domain chloroplast envelope in unicellular green alga Chlamydomonas (Chlamydomonas reinhardtii). We show that this isolated chloroplasts retains translationally active and mRNAs encoding proteins. This is aligned with localized zone, compartment where photosystem subunits encoded plastid genome are synthesized assembled. Roles...
Follicle selection in chicken refers to the process of selecting a follicle enter hierarchy from cohort small yellow follicles (SY) with diameter 6 8 mm. The being selected will develop rapidly and ovulate. is key stage affecting egg-laying performance. Our previous study showed that phosphorylation level lysine (K)-specific demethylase 1A (LSD1) at serine 54 (LSD1Ser54p) was significantly increased F6 compared prehierarchal SY follicles, but its function unclear. Here, mechanism this...
Abstract The lancelet is considered to be a promising laboratory model animal. To establish colonies of lancelet, we collected parental lancelets Branchiostoma belcheri and B. japonicum (previously named as tsingtauense ) with fully developed gonads from Xiamen Rare Marine Creature Conservation Areas (Fujian, China) on dates just before their spawning in the field 2005. Those spawned spontaneously produced thousands upon fertilized eggs. After carefully hatching maintaining for almost 1...
Chloroplast development in plants is regulated by a series of coordinated biological processes. In this work, genetic suppressor screen for the leaf variegation phenotype thylakoid formation 1 (thf1) mutant combined with proteomic assay was employed to elucidate complicated network. We identified mutation ClpR4, named clpR4-3, which leads virescence and also rescues var2 variegation. Proteomic analysis showed that chloroplast proteome clpR4-3 thf1 dominantly controlled providing molecular...
