Stage-Specific RNA Turnover Drives Small RNA Dynamics in Arabidopsis–Colletotrichum Interactions (Carolina E. Armijos, Thi-Thu-Huyen Chu, Richard J. O' Connell, Blake C. Meyers, Patricia Baldrich) doi.org/10.1002/pld3... #PlantScience @aspbofficial @wileyecology @sebiology

Schematic summary of miRNA and tRNA fragment dynamics during the infection stages of C. higginsianum in A. thaliana. The stages shown are in planta appressorium (PA), biotrophic phase (BP), necrotrophic phase (NP), in vitro appressorium (VA), and mycelia (MY). Differential accumulation of the sRNAs is color coded: green for A. thaliana, brown for C. higginsianum, and black for miRNAs and tRNA fragments that are similarly differential accumulation in both host and pathogen. Upregulation is indicated by upward arrows, and downregulation by downward arrows.

The Structure of the Chemotype Determining Locus in Cannabis sativa (Keith Allen, Anthony Torres, Reginald Gaudino) doi.org/10.1002/pld3... #PlantScience @aspbofficial @wileyecology @sebiology

Functional characterization of recombinant cannabinoid oxidocyclases. Purified proteins, secreted from sf9 cells infected with recombinant baculovirus, were functionally characterized. All assays were supplemented with CBGA precursor. Activity presented as percent of total CBGA converted was normalized against canonical CBCAS activity at 100% functionality. With CBCA as the dominant product of these enzymes, comparative analysis of activity for Clade C.4, Clade C.5, and Clade C.6 was carried out against CBCAS. In assays with purified protein from sf9 expression lower activity of CBCA production was observed in Clade C recombinant enzymes. Clade C.4 comparative activity was 26% of CBCAS, while Clade C.5 and Clade C.6 were 16% and 11%, respectively, of CBCAS.

A dual-fluorescence based assay for the evaluation of transcript leaders. Wild-type and mutated 5′ leaders are cloned into the acceptor backbone in one step via BpiI, followed by agroinfiltration in N. benthamiana, leaf disc excision, and two-channel fluorescence quantification in a 96-well plate reader 3-day postinfiltration. RFU, relative fluorescent units.
