まとめ

トウモロコシの発芽時の低温耐性には、抗酸化防御の強化とフェニルプロパノイドおよびフラボノイド経路の活性化が関与する。ZmPER5のような主要遺伝子は、トウモロコシの耐寒性の向上に不可欠である。

背景:

春先の低温はトウモロコシの発芽と収量に悪影響を与える。;トウモロコシの低温耐性の遺伝的および分子的基础を理解することは、農業生産性にとって不可欠である。

結論:

発芽時のトウモロコシの低温耐性は、抗酸化システムの強化と特定の代謝経路が関与する複雑な形質である。;フェニルプロパノイド由来のリグニン生合成の活性化とフラボノイドの蓄積は、耐寒性に寄与する。;ZmPER5およびその他同定された遺伝子は、耐寒性トウモロコシ品種の育種のための有望な標的である。

Responses to Heat and Cold Stress

14.6K

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Introduction to Plant Diversity

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.

Transgenic Plants

8.4K

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...

Transcription

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
Transcription Can Produce Different Kinds...
