Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack
New Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

Loss of E3 ligase HvST1 function substantially increases distal crossover frequency
New Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.
