利用组织培养技术进行器官再生是植物营养繁殖和基因编辑等现代农业分子育种技术应用的基础。在经典的两步法组织培养技术中，首先在愈伤组织诱导培养基上利用高浓度生长素使外植体产生愈伤组织，再在含有高浓度细胞分裂素的芽诱导培养基上诱导愈伤组织再生为芽，或在含有低浓度生长素的根诱导培养基上诱导愈伤组织再生为根。在模式植物拟南芥中发现，愈伤组织类似于根尖分生组织（Dev Cell, 18: 463-471, 2...

生物膜贴壁培养具有高光效、高产率、易采收和高效节水的巨大优势，是突破微藻生产效率和成本瓶颈的变革性培养技术之一，近十年来受到国内外广泛关注。不同于传统的微藻开放池和光反应器悬浮培养，人们对微藻生物膜的光碳传输和生长机制一直不清楚。光和溶解性无机碳在微藻生物膜内如何传输？如何衰减？能穿透多深？光合作用在哪里发生？生物膜如何增厚？环境因子如何控制生物膜生长？近日，中国科学院青岛生物能源与过程研究所研究...
对于高维带粘性的标量守恒律方程和可压缩Naiver-Stokes方程，证明了平面粘性激波和疏散波在高维周期扰动下的非线性渐近稳定性。证明的关键在于如何构造合适的拟设来抵消在无穷远处持续振荡的周期扰动，从而可以建立能量估计。特别地，在激波稳定性的结果中，文章给出把扰动的零频和非零频分开估计、再结合反导数技巧的新想法，使得基本能量方法可以得到利用，同时还揭示了周期振荡对激波稳定性的影响与非振荡扰动有本...
