Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Impact of Seasonal Composition on the Long‐Term Performance of Post‐Consumer Recycled Polypropylene

Journal of Applied Polymer Science, EarlyView.
Ten batches of post‐consumer polypropylene recyclate were examined over a period of 15 months. Despite identical MFR and density specifications, there were significant differences in their composition, affecting mechanical performance. Elongation at break and crack resistance varied particularly strongly.
