A cost‐effective DNA extraction protocol for long‐read sequencing in non‐model plants
Applications in Plant Sciences, EarlyView.Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Chemistry – A European Journal, EarlyView.The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.
