AtPRMT3-RPS2B promotes ribosome biogenesis and coordinates growth and cold adaptation trade-off

Zhen Wang, Xiaofan Zhang, Chunyan Liu, Susan Hanley Duncan et autres

Translation, a fundamental process regulating cellular growth and proliferation, relies on functional ribosomes. As sessile organisms, plants have evolved adaptive strategies to maintain a delicate balance between growth and stress response. But the underlying mechanisms, particularly on the translational level, remain less …

A mitochondrial pentatricopeptide repeat protein enhances cold tolerance by modulating mitochondrial superoxide in rice

Xiaofeng Zu, Lilan Luo, Zhen Wang, Jie Gong et autres

Cold stress affects rice growth and productivity. Defects in the plastid-localized pseudouridine synthase OsPUS1 affect chloroplast ribosome biogenesis, leading to low-temperature albino seedlings and accumulation of reactive oxygen species (ROS). Here, we report an ospus1-1 suppressor, sop10. SOP10 encodes a mitochondria-localized pentatricopeptide …

Pseudouridylation of chloroplast ribosomal RNA contributes to low temperature acclimation in rice

Zhen Wang, Jing Sun, Xiaofeng Zu, Jie Gong et autres

Ribosomal RNAs (rRNAs) undergo many modifications during transcription and maturation; homeostasis of rRNA modifications is essential for chloroplast biogenesis in plants. The chloroplast acts as a hub to sense environmental signals, such as cold temperature. However, how RNA modifications contribute to low …

Immunopurification of Mitochondria from Arabidopsis

Lilan Luo, Yajun He, Jiayang Li, Hong Jun Yu

Isolation of mitochondria from plant tissues, especially green leaves, is particularly difficult because of chloroplast contamination. Compared to other techniques for purifying plant mitochondria, the immunopurification method has a number of advantages: it rapidly purifies the mitochondria within several minutes, avoids loss …

Malate transported from chloroplast to mitochondrion triggers production of ROS and PCD in Arabidopsis thaliana

Yannan Zhao, Lilan Luo, Jiesi Xu, Peiyong Xin et autres

Programmed cell death (PCD) is a fundamental biological process. Deficiency in MOSAIC DEATH 1 (MOD1), a plastid-localized enoyl-ACP reductase, leads to the accumulation of reactive oxygen species (ROS) and PCD, which can be suppressed by mitochondrial complex I mutations, indicating a signal …

Deficient plastidic fatty acid synthesis triggers cell death by modulating mitochondrial reactive oxygen species

Jian Wu, Yuefeng Sun, Yannan Zhao, Jian Zhang et autres

Programmed cell death (PCD) is of fundamental importance to development and defense in animals and plants. In plants, a well-recognized form of PCD is hypersensitive response (HR) triggered by pathogens, which involves the generation of reactive oxygen species (ROS) and other signaling …
