Investigating the mechanism of chloroplast singlet oxygen signaling in the Arabidopsis thaliana accelerated cell death 2 mutant

This study investigates chloroplast singlet oxygen signaling in the Arabidopsis thaliana acd2 mutant, identifying potential pathways and their roles in stress responses.

A genetic screen for dominant chloroplast reactive oxygen species signaling mutants reveals life stage-specific singlet oxygen-signaling networks

This study identifies life stage-specific singlet oxygen signaling networks in Arabidopsis by screening for mutants that suppress chloroplast 1O2-initiated programmed cell death.

Multiple pathways mediate chloroplast singlet oxygen stress signaling

This study identifies multiple chloroplast singlet oxygen signaling pathways in Arabidopsis by comparing 1O2-producing mutants and analyzing their gene expression and genetic interactions.

Singlet oxygen leads to structural changes to chloroplasts during degradation in the Arabidopsis thaliana plastid ferrochelatase two mutant

The paper investigates chloroplast degradation in Arabidopsis thaliana under singlet oxygen stress, finding structural changes and increased plastoglobule activity in degrading chloroplasts.

Singlet oxygen-dependent chloroplast degradation is independent of macroautophagy in the Arabidopsis ferrochelatase two mutant

This study investigates 1O2-induced chloroplast degradation in Arabidopsis fc2 mutants and finds that macroautophagy is not required, while microautophagy may be involved.

Chloroplast quality control pathways are dependent on plastid DNA synthesis and nucleotides provided by cytidine triphosphate synthase two

This study identifies CTPS2 as essential for chloroplast quality control by supplying nucleotides for chloroplast DNA maintenance and signaling, showing its distinct role from CTPS3.

Plastid gene expression is required for singlet oxygen-induced chloroplast degradation and cell death

The paper identifies two chloroplast proteins, PPR30 and mTERF9, required for plastid gene expression and ROS signaling leading to chloroplast degradation and cell death.
