概括

酸 (KClO₃) 通过激活吉伯雷林和自主通路,可能通过氧化应激,诱导非季节长开花. 这与依赖季节性线索的自然开花形成鲜明对比,为长期作物改进提供了洞察力.

科学领域:

植物生物学植物生物学
基因组学就是基因组学.
农业科学农业科学

背景情况:

龙 (Dimocarpus longan Lour.) 是一种长的植物. 是一个热带水果作物.
非季节的开花可以使用酸 (KClO) 来诱导.
在KClO₃诱导的开花背后的分子机制还不太清楚.

研究的目的:

阐明KClO₃诱导长期开花的分子机制.
为了组装和分析长基因组.
为了比较自然和诱导的开花中的开花路径.

主要方法:

长品种"Shixia"的基因组测序和组装.
基因组与李奇的比较.
在不同的开花条件下对龙进行转录形状分析.
在Arabidopsis中进行基因表达分析.

主要成果:

组装了一个高质量的longan基因组.
KClO₃诱导的开花涉及吉伯雷林和自主通路,抑制DlDDF1.
在"Sijimi"的永久开花与光周期基因表达有关.
DlDDF1过度表达延迟了开花,部分由KClO₃逆转.

结论:

由KClO₃诱导的长期开花是由氧化应激和通过DlDDF1抑制的吉伯雷林信号介导的.
自然的开花是由季节性因素调节的.
这些发现为长开花的遗传改进提供了基础.

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
