Abstract

Two polygalactolipids, designated as components A and B, were isolated from spinach chloroplasts and were also obtained from glycolipid products synthesized with chloroplast enzymes using uridine diphosphate galactose as a galactose donor. These lipids were purified by column and thin layer chromatography. Chemical analysis of component A indicates that the lipid is trigalactosyl diglyceride, whereas component B behaves like tetragalactosyl diglyceride on a thin layer plate. The major fatty acid in trigalactosyl diglyceride was alpha-linolenic acid. Relative amount (molar ratio) of galactolipids in spinach chloroplasts was monogalactosyl diglyceride:digalactosyl diglyceride:trigalactosyl diglyceride:(tetragalactosyl diglyceride) = 60:30:5:1.

The proxiome of a plant viral protein with dual targeting to mitochondria and chloroplasts revealed MAPK cascade and splicing components as proviral factors.

The coat protein (CP) of the melon necrotic spot virus (MNSV) is a multifunctional factor localized in the chloroplast, mitochondria, and cytoplasm, playing a critical role in overcoming plant defenses such as RNA silencing (RNAi) and the necrotic hypersensitive response. However, the molecular mechanisms through which CP interferes with plant defenses remain unclear. Identifying viral-host interactors can reveal how viruses exploit fundamental cellular processes and help elucidate viral survival strategies. Here, we employed a TurboID-based proximity labeling approach to identify interactors of both the wild-type MNSV CP and a cytoplasmic CP mutant lacking the dual transit peptide (ΔNtCP). Of the interactors, eight were selected for silencing. Notably, silencing MAP4K SIK1 and NbMAP3Kε1 kinases, and a splicing factor homolog NbSMU2 significantly reduced MNSV accumulation, suggesting a proviral role for these proteins in plants. Yeast two-hybrid and bimolecular fluorescence complementation assays confirmed the CP and ΔNtCP interaction with NbSMU2 and NbMAP3Kε1 but not with NbSIK1, which interacted with NbMAP3Kε1. These findings open up new possibilities for exploring how MNSV CP might modulate gene expression and MAPK, thereby facilitating MNSV infection.

Effects of light on chloroplast translation in Marchantia polymorpha are similar to those in angiosperms and are not influenced by light-independent chlorophyll synthesis.

Translation of the chloroplast psbA mRNA in angiosperms is activated by photodamage of its gene product, the D1 subunit of photosystem II (PSII), providing nascent D1 for PSII repair. The involvement of chlorophyll in the regulatory mechanism has been suggested due to the regulatory roles of proteins proposed to mediate chlorophyll/D1 transactions and the fact that chlorophyll is synthesized only in the light in angiosperms. We used ribosome profiling and RNA-seq to address whether the effects of light on chloroplast translation are conserved in the liverwort Marchantia (Marchantia polymorpha), which synthesizes chlorophyll in both the dark and the light. As in angiosperms, ribosome occupancy on psbA mRNA decreased rapidly upon shifting plants to the dark and was rapidly restored upon a transfer back to the light, whereas ribosome occupancy on other chloroplast mRNAs changed very little. The results were similar in a Marchantia mutant unable to synthesize chlorophyll in the dark. Those results, in conjunction with pulse-labeling data, suggest that light elicits a plastome-wide activation of translation elongation and a specific increase in psbA translation initiation in Marchantia, as in angiosperms. These findings show that light regulates chloroplast translation similarly in vascular and non-vascular plants, and that constitutive chlorophyll synthesis does not affect light-regulated psbA translation initiation. Additionally, the translational outputs of chloroplast genes are similar in Marchantia and angiosperms but result from differing contributions of mRNA abundance and translational efficiencies. This adds to the evidence that chloroplast mRNA abundance and translational efficiencies co-evolve under selection to maintain protein outputs.

The chloroplast 16S rRNA dimethyltransferase BrPFC1 is required for Brassica rapa development under chilling stress.

Chloroplast ribosomal RNA (Ch-rRNA) methylation is critical for plant development and response to low temperatures. Several Ch-rRNA methyltransferases and their catalytic modes, as well as biological relevance, have been reported in model plant species. However, Ch-rRNA methyltransferases and their functional significance remain poorly characterized in crops, including leafy vegetables such as Chinese cabbage. In this study, we screened an EMS-mutagenized Chinese cabbage population and identified a yellow inner leaf (yif) mutant. This mutant develops yellowing inner leaves with reduced chlorophyll accumulation and ultrastructure-impaired chloroplasts under low-temperature conditions. Genetic analysis revealed a premature termination mutation in BrPFC1, encoding the chloroplast-localized 16S rRNA dimethyltransferase. The BrPFC1 mutation (yif) disrupts the dimethylation of 16S rRNA. The cold-sensitive phenotype of the yif mutant can be explained by temperature-dependent defects in the maturation and assembly of chloroplast ribosomes at 4°C. Through integrated analysis of chloroplast and nuclear transcriptomes coupled with translational profiling at 25°C and 4°C, we established that low temperature preferentially upregulates transcripts encoding nuclear-derived ribosomal proteins, while defective 16S rRNA specifically compromises the translational efficiency of chloroplast-encoded photosynthetic complex and ribosomal protein at 4°C. These findings establish rRNA modification by BrPFC1 as a critical regulatory layer for optimizing chloroplast translational efficiency at 4°C, providing mechanistic insights into post-translational adaptation strategies in Chinese cabbage.
