Abstract:

A breast basic conserved 1 (BBC1) cDNA has been isolated from common wheat (Triticum aestivum L.). Analysis of amino acid sequence derived from the cDNA showed that the wheat BBC1 was highly hydrophilic and rich in alanine, lysine, glutamic acid and arginine residues. The transcription of wheat BBC1 mRNA was regulated by low temperature. Southern blotting analysis showed that BBC1 existed as a small family in common wheat genome.

摘要： 从小麦(Triticum aestivum L．)中克隆了一个BBC1基因的cDNA。分析结果表明，该基因编码一亲水多肽，富含丙氨酸、赖氨酸、精氮酸和谷氦酸。该基因的转录受低温调控。在小麦基因组中，BBC1基因以一个小家族的形式存在。
