概括
在Medicago中,多个SOC1类基因对于开花至关重要. 缺乏所有三种MtSOC1基因的三重突变未能开花,这表明在过渡到开花过程中重叠的角色.
科学领域:
- 植物生物学 植物生物学
- 遗传学 遗传学 是一个
- 分子生物学分子生物学
背景情况:
- 开花时间对于植物的适应和作物产量至关重要.
- 类似SOC1的基因编码着调节开花的MADS转录因子.
- 一种豆类模型Medicago truncatula具有三种MtSOC1对应物,与一个SOC1.1的Arabidopsis不同.
研究的目的:
- 研究三种Medicago truncatula SOC1-like (MtSOC1) 基因在开花时间控制中的作用.
- 为了生成和描述三重突变系 (Mtsoc1a Mtsoc1b Mtsoc1c),以了解潜在的重叠功能.
主要方法:
- 使用CRISPR-Cas9基因编辑来创建三重突变系.
- 进行了基因型和基因表达分析 (RNA-seq,RT-qPCR).
- 在花诱导条件下对突变系的表型分析 (长日之后的化).
主要成果:
- 两个独立的三重突变系显示在花诱导条件下完全无法开花.
- 不开花的植物在所有三种MtSOC1基因的突变方面均具有同胞性.
- 基因表达数据证实,这些植物仍然处于植物状态.
结论:
- 多个MtSOC1基因在促进Medicago的向开花过渡方面具有关键的重叠作用.
- MtSOC1a,MtSOC1b和MtSOC1c的综合损失导致一种非开花的表型,与单个突变不同.
- 这凸显了对Medicago属内花期调节中paralog冗余的重要性.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
