概括

Tef [Eragrostis tef] 寄宿易感性与早期根细胞壁成熟有关. 选择较慢的根成熟率的Tef线可以减少住宿,并使机械收获成为可能.

科学领域:

农业科学农业科学
植物生物学植物生物学
生物技术是生物技术.

背景情况:

泰夫 (Eragrostis tef) 是一种重要的无质作物,但其住宿易感性阻碍了现代农业和机械收获.
由于根或茎的故障引起的沉积,导致了Tef生产的显著收获损失.

研究的目的:

为了研究冠根的微观结构性质,并了解它们在产生耐受性/易感性方面的作用.
分析细胞壁成熟和组成与遗传寄存倾向的关系.

主要方法:

使用扫描电子显微镜,微型计算机断层扫描和拉曼微型光谱学对Tef根截面的表征.
在出现5周和10周后对植物进行分析,比较不同基因型的状和置植物.

主要成果:

宿舍敏感的Tef基因型显示较早的组织成熟,包括aerenchyma发展,密集的化和高度交联的化.
住宿并没有显著影响根组织组织学;细胞壁组成是基因型依赖的和典型的,无论植物的支持.
拉曼微光谱学有效地监测了不同遗传寄存倾向的Tef根的细胞壁成熟.

结论:

在Tef根内皮和圆筒组织中细胞壁的组成和成熟可以使用拉曼微光谱学来描述.
选择延迟皇冠根成熟的tef线是减少宿舍的有希望的策略.
减少在tef中的住宿将促进机械收获,提高农业效率.

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 disassembly and...
