Summary: This article introduces a significant cellular process, autophagy, which degrades unwanted or damaged macromolecules and organelles through the lysosome or vacuole for recycling. Selective autophagy was found to play a crucial role in regulating chloroplast protein import and enhancing stress tolerance in plants.

Summary: Plastid-encoded RNA polymerase (PEP)-dependent transcription is crucial for chloroplast development and plant growth. PD1 has been identified as a novel regulator for PEP-dependent gene expression and chloroplast development in Arabidopsis. PD1 interacts with PEP core subunit beta and is essential for the accumulation of PEP-beta, impacting chloroplast development in Arabidopsis.

Summary: This study reports the importance of the PtrDJ1C factor in chloroplast development and lignin accumulation in poplar. Knockout of the PtrDJ1C gene led to impaired chloroplast development and abnormal lignin deposition. These findings contribute to a better understanding of chloroplast development and metabolism in woody plants.

Summary: This study reveals that the DJ-1D protein in plants has the ability to repair glycated DNA, RNA, and proteins, providing robust tolerance to endogenous and exogenous stresses. The study also shows that DJ-1D can reduce the formation of reactive carbonyls, thereby suppressing the accumulation of advanced glycated end-products. Furthermore, the study indicates the existence of a new DNA repair pathway in plants.

Summary: This study investigated the functions of plant plastid ribosomal protein L18s (PRPL18s) and found that they play critical roles in plastid ribosome biogenesis, plastid intron splicing, and chloroplast development, and are essential for plant survival.

Summary: Research has found that the levels of polyamines in Arabidopsis thaliana are comparable to classic phytohormones but significantly lower than putrescine, spermidine, and spermine. Further study of the T-Spm biosynthetic mutant acl5 has revealed core components related to the formation of nodule-like structures. The genetic relationship between rRNA modification and T-Spm-mediated growth and development has been established through the study of suppressors of acl5.

Summary: The study reports the discovery and characterization of a new tiny albino 1 (nta1) mutant in Arabidopsis, which shows severe defects in the accumulation of cytochrome b6f (Cyt b6f) complex and chloroplast development. The nta1 phenotype is caused by disruption of a single nuclear gene, NTA1, which encodes a conserved thylakoid membrane protein. NTA1 interacts with multiple subunits of Cyt b6f and plays an essential role in its assembly and the development of chloroplast.

Summary: By using the organelle glue technique, we manipulated organelle interactions and controlled the plant metabolome at the pathway level. This study demonstrates the potential for designing plants with desirable metabolic activities by artificially controlling organelle interactions through genetic modification.

Summary: FtsH12 plays a crucial role in seedling development of Arabidopsis thaliana, affecting plastid import machinery and chloroplast development. Changes in FtsH12 abundance lead to alterations in protein composition and structure of the chloroplast, impacting overall plant growth and leaf coloration.

Summary: Magnesium (Mg2+) is crucial for photosynthesis in plants and algae, and its concentration in chloroplasts is tightly regulated by transport proteins. This study identifies three different transporters and investigates their roles in maintaining chloroplast Mg2+ homeostasis and regulating photosynthesis in Arabidopsis thaliana and Chlamydomonas reinhardtii. The findings reveal essential but differential roles of these transporters in chloroplast Mg2+ homeostasis and highlight their conservation across plant species.

Summary: The researchers investigated the rate and trajectory of mitochondria in Arabidopsis thaliana mesophyll cells using confocal laser-scanning microscopy. They discovered that mitochondria migrate through wiggling during their association with chloroplasts, shedding light on the impact of mitochondria-chloroplast interaction on mitochondrial movement.

Summary: The role of translational control in maintaining proteostasis in plants is important, but the mechanisms for coordinating translation rates during development and stress response are not well understood. In Arabidopsis, the eEF1B complex is composed of three subunits, with eEF1B gamma having an unknown function. By studying Arabidopsis mutants with reduced eEF1B gamma levels, its essential role in plant growth and development was revealed, along with its impact on translation. The rapid localization of eEF1B subunits to cytoplasmic foci may facilitate adaptation of translation rates during heat stress.
