Abstract

The commercial value of Kurles pears pericarp, a popular and favored fruit for its unique aroma and refreshingly crisp texture, had sharply decreased because of a rust breakout of the beloved pear in China during the atmosphere-controlled storage. High performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) were used to analyze rust spots on the pericarp of Kurle pears. Therefore, the chemical compounds of four various eluates, originating from the rust-colored substance collected from the pears pericarp effected, were identified successfully for the first time, which were just rhein, aloe-emodin, chrysophanol and emodin, respectively. Taken together with microstructure characteristics for rust-spots of Kurle pear pericarp, it was no doubt that these eluates were the main factors affecting the rust spots on the pericarp of the Kurle pears during the atmosphere-controlled storage, which was a sign and consequence resisting the undesirable stress of the external environment.

Anionic lipids stabilize etioplast prolamellar bodies and facilitate thylakoid biogenesis during etioplast-to-chloroplast differentiation

Etioplasts of dark-grown angiosperm seedlings contain prolamellar bodies (PLBs), lattice-like membranes that are quickly transformed into thylakoids upon illumination. Phosphatidylglycerol (PG) and sulfoquinovosyldiacylglycerol (SQDG) are major anionic lipids in these membranes, but their roles in etioplast-to-chloroplast differentiation remain unclear. We analyzed Arabidopsis thaliana mutants with reduced PG biosynthesis (pgp1-1), complete SQDG deficiency (sqd1), and the pgp1-1 sqd1 double mutant. Although pgp1-1 etioplasts showed a loosened PLB lattice when fixed under white light, they retained regular, wild-type-like lattices when fixed under infrared light, suggesting that their PLBs were more susceptible to light-induced disassembly. The rapid PLB disassembly in pgp1-1 upon illumination was accompanied by rapid conversion of dark-accumulated protochlorophyllide to chlorophyll and lamellar membrane formation, suggesting a link between membrane remodeling and chlorophyll formation. However, subsequent chlorophyll accumulation through de novo biosynthesis was retarded in illuminated pgp1-1 seedlings, whereas photosynthetic electron transport was quickly activated. Although sqd1 showed no obvious defects, pgp1-1 sqd1 exhibited more severe defects than pgp1-1, particularly in internal membrane formation, chlorophyll accumulation, photosynthetic activation, and photosynthetic gene expression. These findings suggest that PG is crucial for membrane-associated processes during etioplast-to-chloroplast differentiation, while SQDG may help maintain chloroplast development when PG availability is limited.

PHYRE, a Translated uORF, is Required for Phytochrome B Translation and Photomorphogenesis in Arabidopsis

Translational control allows cells to adjust protein output independently of transcription, yet the mRNA-encoded mechanisms that govern this regulatory layer remain poorly understood. Upstream open reading frames (uORFs) are among the most prevalent translational regulatory elements in eukaryotic genomes; however, characterised examples of activating uORFs that promote rather than inhibit downstream translation are exceedingly rare. Here we show that efficient expression of phytochrome B (phyB), the master red-light photoreceptor of Arabidopsis thaliana, requires translation of a short uORF in its own 5'UTR, which we name PHYTOCHROME REGULATOR (PHYRE). Loss of PHYRE function phenocopies phyB null mutants across germination, hypocotyl growth, leaf development, and flowering time. PHYRE activity depends on its encoded peptide sequence, and the spacing between PHYRE and the PHYB start codon is a critical determinant of downstream translation efficiency, consistent with a position-dependent reinitiation mechanism. PHYRE-like elements are conserved across eudicots, establishing uORF-mediated translational gating as a broadly maintained regulatory layer controlling a master photoreceptor.

The chloroplast-localised transporter RETICULATA controls palisade mesophyll cell division and expansion

Plant leaves contain extensive intercellular air spaces, which contribute to photosynthetic capacity and water use efficiency in different environments. Despite this importance, the developmental mechanisms that control leaf air space patterning are poorly understood. For over 20 years it has been known that plants with disrupted chloroplast biogenesis and metabolism have increased intercellular air spaces, but the underlying molecular mechanism is unknown. Here, we characterise leaf air space morphogenesis in mutants of the chloroplast amino acid transporter RETICULATA (RE), which has enlarged air spaces. We show that the reticulata-6 (re-6) loss of function mutant exhibits increased air space expansion specifically in the palisade, and not the spongy, mesophyll. We also show that RE does not regulate air space patterning via programmed cell death, via a change in stomatal density or a change in cell identity of the mesophyll tissue. Instead, we quantify mesophyll cell morphology and division rates to show that RE acts by promoting early palisade cell division and suppressing later cell expansion. Overall, we show that RE specifically regulated palisade mesophyll morphogenesis and air space patterning and hypothesise that chloroplasts may act to regulate air space patterning in the palisade mesophyll in response to light.
