针对温带散孔材树种如何响应气候变暖与干旱的科学问题，研究人员通过分析中国东北四种优势树种（Acer mono、Betula platyphylla、Populus davidiana、Tilia amurensis）的木质部解剖特征，揭示了其水力策略的分化：A. mono和B. platyphylla采取保守策略（减少导管数量与尺寸），而P. davidiana和T.

本研究通过农杆菌介导转化技术，将小黑杨（Populus simonii × P. nigra）的PsnCHS7基因在杂种杨（P. davidiana × P. bolleana）中异源表达，显著提升转基因植株槲皮素含量及查尔酮合成酶（CHS）活性。实验证实，取食转基因杨树的舞毒蛾（Lymantria dispar）幼虫生长迟缓，其细胞色素P450、谷胱甘肽S-转移酶和羧酸 ...
