TL;DR: Functional redundancy among three PHR1 orthologs in rice (OsPHR1, Os PHR2, and OsPHR3) is identified using phylogenetic and mutation analysis and it is proposed that OsPHRs 1, 2, and 3 form a network and play diverse roles in regulating Pi signaling and homeostasis in rice.

TL;DR: A forward genetics approach was used to investigate the mechanism of arsenate (As(V) tolerance and accumulation in rice and identified OsHAC4 as the causal gene for the As(V)-hypersensitive phenotype.

TL;DR: Results indicate that OsCLT1 plays an important role in glutathione homeostasis, probably by mediating the export of γ-glutamylcysteine and glutathion from plastids to the cytoplasm, which in turn affects As and Cd detoxification in rice.

TL;DR: It is shown that LIR1 interacts with LEAF-TYPE FERREDOXIN-NADP+ OXIDOREDUCTASE (LFNR), an essential chloroplast enzyme functioning in the last step of photosynthetic linear electron transfer, and increases the affinity of LFNRs for TIC62 and that the rapid light-triggered degradation of the Lir1 coincides with the release of the LFNR from the thylakoid membrane.

TL;DR: In this article, a protein which has arsenic acid reduction activity and is encoded by using an arsenic acid reductase gene OsHAC4 of rice was revealed, which has an amino acid sequence as shown in SEQ ID NO: 2.
