Result The fiber color was controlled by 4 pairs of genes at least. Whether the long fiber and linter were brown was controlled by a pair of dominant genes separately, the type of its fiber color was controlled by 2 pairs of minor genes at least, showing different types such as light brown and brown approaching white. The long fiber in F2 generation had 3 phenotypes altogether of brown long fiber and brown linter, white long fiber and white linter, white long fiber and brown linter, showing there was interaction among genes and the expression of dominant gene in brown long fiber inhibited the expression of recessive gene of linter color.

Floral organ determination is best explained by the ABCDE model postulated by genetic studies of Arabidopsis thaliana. Sepals are determined by A and E class genes; petals are determined by A, B, and E; stamens by B, C, and E; and carpels by C and E class genes. A, B, C, and E class gene lineages are known having duplicated several times during the evolution of angiosperms. One of the noted major duplication events occurred in the origin of the early angiosperms, leading to the formation of subgroups of B/C/D/E class. Another one occurred near the basal eudicots and gave rise to further subgroups in A/B/C/D/E class genes among core eudicots. The phylogenetic position of the family Buxaceae is located right where the second major duplication of ABCDE genes might have occurred, which is supported by multiple gene (nuclear 18S rDNA, chloroplast rbcL and atpB) phylogenetic analyses.

目前经由模式植物阿伯芥的研究，建花部器官决定基因的调控，即花萼由A、E 群基因共同决定，花瓣由A、B、E 群基因，雄蕊由B、C、E 群基因，而心皮由C 和E 群基因决定。A、B、C、E 四群基因在被子植物的演化过程中发生过次的复制事件，其中比较重要的一次发生在早期被子植物演化出之时，形成B/C/D/E 群基因的次系群；另一次复制事件则发生在真双子植物基群附近，形成仅於核心真双子植物的A/B/C/D/E 群基因之次系群。

Based on these observations, we predict that the transmission of GA-signaling genes occurs in a sporophytic manner, since the protein products and/or mRNA transcripts of these genes may be introduced into pollen-carrying mutant alleles, whereas GA synthesis genes are transmitted in a gametophytic manner, since these genes are preferentially expressed after meiosis.

基于这些观察，我们预测该遗传算法，基因信号传输时，在孢子的方式，因为蛋白质的产品和/或基因这些基因的转录可以引入花粉携带突变基因，而合成的基因遗传传递以配子体的态度，因为这些基因是优先减数分裂后表示。

We initiated a genetic screen for Drosophila olfactory genes by means of SG18.1-Gal4/UAS system: The result validates our screen as an rapid, effective approach for recovering genes controlling glomerular map patterning; From a misexpression screen of 1,515 P{GS} lines, we identified 23 genes that, when forcibly expressed in the olfactory receptor neurons, disrupted the stereotyped anatomy of the Drosophila antennal lobes; These genes, which have not been shown previously to control olfactory map development, encode novel proteins as well as proteins with known roles in axonal outgrowth and cytoskeletal remodeling.

本文首次利用SG18.1-Gal4／UAS基因筛选系统对果蝇嗅觉基因进行了筛选和鉴定：结果表明，所采用的方法可以快速、有效地分离到果蝇嗅觉相关基因；从1515株果蝇P{GS}品系分离到86株突变体，其中40株有明显表型，从中鉴定了23个基因，这些基因在ORN强迫表达时可以损坏果蝇嗅叶的固有结构；在筛选中发现的一些调节嗅觉图谱发育的基因可以编码新蛋白或编码参与轴突生长和细胞骨架重塑的蛋白；为了便于研究，根据基因的功能和所编码蛋白的特点，我们对分离到的基因进行了分类，即参与轴突引导和突触产生、调节转录、调节细胞骨架和功能未确定或未知的基因；并通过对嗅觉感觉器的检测发现，除了调节转录的基因外，其他基因对触觉器的数量和分布影响不明显。

Deduced by the proportion of typical sterile plants and normal fertile plants in segregative generations derived from WA zhenqiuA/6078 that:I gene could inhibit the expression of Rf gene completely by the heterozygosity of 1 pair of Rf in genotype;and only reduce the expression of Rf genes with two heterozygous Rf genes in genotype ;but it would never inhibit the expression of Rf genes if the genotype included 3 pairs of heterozygous Rf genes. When Rf gene was homozygous,the / gene could not inhibit the expression of it.

In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein.
