概括

这项研究揭示了djulis (Chenopodium formosanum) 如何改变尖的颜色. 关键的基因和颜料,包括安东素和贝他林,在成熟过程中共同工作,提供了对Amaranthaceae植物色彩的洞察力.

科学领域:

植物生物学植物生物学
生物化学生物化学
基因组学就是基因组学.

背景情况:

朱利斯 (Chenopodium formosanum) 是一种装饰植物,属于阿玛兰氏家族,有着生动的尖,但其颜色变化的机制尚不清楚.
了解颜色变化对于欣赏djulis的装饰价值和潜在应用至关重要.

研究的目的:

阐明在发育过程中djulis尖峰中安东氨酸生物合成和颜色变化的分子机制.
为了确定关键的基因和代谢途径参与色素积累.

主要方法:

综合性多态学方法结合了有针对性的代谢学,非有针对性的代谢学和转录学.
分析不同发育阶段的安托西亚宁含量.
定量实时PCR (qRT-PCR) 用于基因表达的验证.

主要成果:

安西安合成主要与黄和安西安生物合成途径有关.
在djulis尖的绿色到红色/色转变期间,观察到28个基因和17种代谢物的显著差异表达.
特定基因的上调 (例如CfCHS3,CfF3H3,CfCYP75A6_1,CfDFRA,Cf3GGT) 促进了delphinidin 3-sambubioside和peonidin 3-galactoside的积累.
安西安素和贝他林在djulis尖中共存,这表明它们在颜色发育中发挥着联合作用.

结论:

已经提出了一种调节Djulis在成熟期间的尖峰中安东氨酸生物合成的途径.
朱利斯尖的颜色变化很可能是由于安东素和贝他林的联合作用.
这项研究为进一步研究安东素调节和Amaranthaceae植物的颜色变异提供了基础.

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
