研究 の 目的:
- アヒルの羽毛の色素沈着を制御する遺伝的メカニズムに関する現在の知識を統合すること。;メラニン生合成と色素沈着パターンに関与する主要な遺伝子と制御ネットワークを特定すること。
主な方法:
- ゲノムワイド関連解析、RNAシーケンシング、全ゲノムリシーケンシング、集団遺伝学を含む最近の進歩の体系的なレビュー。;9つのコアメラニン生成経路遺伝子(MITF、MC1R、TYR、TYRP1、DCT、SOX10、KIT、EDNRB2、MLANA)の分析。;メラニン生合成とチロシン代謝における遺伝子の役割を確認するための機能的濃縮分析。
主要な成果:
- メラニン生成経路は、MITF(マスターレギュレーター)やMC1R(色素型制御)などの遺伝子によって制御され、アヒルの色彩の中心となります。;9つのコア遺伝子が、アヒルの集団全体で羽毛の色素沈着と一貫して関連していました。;MITFとMC1R間のエピスタシス相互作用は、色の遺伝に影響を与え、MITFは白色対黒色の表現型に対して優性を示します。

Epistasis
50.0K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Background and Environment Affect Phenotype
7.4K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Complementation Tests
6.0K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Epistasis Analysis
5.6K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
