使用这种新的系统,研究各种SCW的结构和组装.

主要方法:

使用一种可诱导DEX的系统来异位表达NST3和NST1.
使用先进的显微镜 (旋转盘对焦,场辐射扫描电子显微镜) 和光谱 (振动总频生成,飞行时间二次离子质谱) 进行了结果SCW的特征化.
分析了中等尺度组织,纤维素微纤维素方向和分子组成.

主要成果:

由DEX诱导的NST3和NST1的表达导致Arabidopsis hypocotyls的时间依赖转差.
在表皮细胞中,NST3诱导的SCW显示出体血管 (宏纤维体厚度/方向) 和纤维 (壁厚度) 的特征.
诱导的SCW显示纤维素和红素含量发生变化,具有松散排列的层和各种纤维素角度.

结论:

NST3和NST1可以诱导具有混合特性的SCW,从而影响纤维素和木质素的丰富性和组织.
开发的可诱导系统对于研究各种细胞类型和发育阶段的SCW模式非常有价值.
该系统为在生物能源和生物产品开发中探索子宫外SCW提供了潜力.

Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Role of Microtubules in Cell Wall Deposition

Role of Microtubules in Cell Wall Deposition

Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
