    摘要:

    LBD基因家族是植物所特有的一类转录因子,在植物生长发育过程中起到非常重要的作用。本研究利用生物信息学方法,从萝卜基因组中鉴定出分布于9条染色体上的59个LBD基因。该家族成员结构比较简单,内含子数均不超过3个。萝卜LBD基因可分为Class I和Class II两大类,分别包含50和9个成员。它们在染色体上的分布不均匀,1号染色体上基因数目最多,有18个,而7和8号染色体分别仅有1个LBD基因。对它们在不同组织和发育时期的表达模式研究发现,该基因家族具有一定的时空表达特异性,预测其参与萝卜不同的发育过程。本研究为萝卜LBD基因家族的功能分析奠定了基础。

    Abstract:

    LBD gene family is a kind of plant-specific transcription factors and plays very important role in plant development. In this study, 59 LBD genes distributed on 9 chromosomes of radish genome were identified. The radish LBD genes have simple structures with the intron numbers being less than 3. These LBD genes could be classified into 2 classes (Class I and Class II) according to the phylogeny relationship, including 50 and 9 members, respectively. The number of radish LBDs distributed on different chromosomes has significantly difference, 18 members distributed on chromosome 1 while only one member distributed on chromosome 7 and 8, respectively. The expression patterns of radish LBD genes in different tissues and development stages showed spatial and temporal differences, uncovered their potential diverse function in radish development. These results will be helpful for the functional analysis of the radish LBD genes family.
