Plasmodium falciparum apicoplast SufS is required for both iron-sulfur synthesis and tRNA modification by MnmA, a novel paradigm that is likely to apply to other plastid-containing organisms.

Using barcoded mutagenesis and a high-throughput genetic screen results in the identification of 150 genes that affect lipid accumulation in a non-model yeast system.
A new tool that allows specific subpopulations of telomerase RNAs in vivo forces a thorough revision of the telomerase maturation pathway and suggests a new function for Mex67.

N6-methyladenosine (m6A) reader Pho92 is directed by Paf1C to meiotic mRNAs in an m6A-dependent and independent manner and promotes CCR4-NOT-mediated mRNA decay of m6A modified transcripts contingent on translation.

Genomics and genetics were used to identify specialized metabolites employed by Pseudomonas bacteria to suppress the growth of potato pathogens, which revealed a key role for cyclic lipopeptides.
Multiple cryo-electron microscopy structures of a plant ABC transporter exporting glutathione derivatives captured a closed conformation proposed to enforce the export directionality, while a complex central to the coupling mechanism containing both glutathione and closed nucleotide binding domains remains elusive.

Non-invasive mRNA stability measurements reveal that transcript lifetime is governed by a competition with translation initiation on a transcriptome-wide level.
