Transport of phenoxyacetic acid herbicides by PIN-FORMED auxin transporters

Schulz et al show that PIN-FORMED auxin transporters transport a range of phenoxyacetic acid herbicides across the membrane. They go on to characterize the molecular determinants of substrate specificity using a variety of different substrates as well as protein mutagenesis to probe the binding site.

Root RADAR: how ‘rhizocrine’ signals allow roots to detect and respond to their soil environment and stresses

Pandey et al discuss how hormones can act ‘outside the plant’ as ‘rhizocrine’ signals that function to improve plant resilience to different soil stresses. They also propose a novel signalling paradigm termed ‘root RADAR’ where rhizocrine levels change in soil in response to environmental stresses, feeding back to roots and triggering adaptive responses.

Single cell omics extends metabolic regulon via orthologous transcription factors from a pair of medicinal plant species

Through single cell multi-omics experiments, Bui et al detected rare MIA biosynthetic cells in Camptotheca acuminata leaf and stem, extending the metabolic regulon with insights from the related species Catharanthus roseus.
