Gene expression analysis in the larval silk gland of the eri silkworm Samia ricini

引用

Insect Science 2016年第6期23卷 791-804页

作者： Takuya Tsubota Kimiko yamamoto Kazuei Mita hideki Sezutsu Transgenic Silkworm Research Unit Ibaraki 305-8634Japan Insect Genome Research Unit National Institute of Agrobiological Sciences Ibaraki 305-8634Japan

Insects produce silk for a range of purposes. In the Lepidoptera, silk is utilized as a material for cocoon production and serves to protect larvae from adverse environmental conditions or predators. Species in the Saturniidae family produce an especially wide variety of cocoons, for example, large, golden colored cocoons and those with many small holes. Although gene expression in the silk gland of the domestic silkworm （Bombyx mori L.） has been extensively studied, considerably fewer investigations have focused on members of the saturniid family. Here, we established expression sequence tags from the silk gland of the eri silkworm （Samia ricini）, a saturniid species, and used these to analyze gene expression. Although we identified thefibroin heavy chain gene in the established library, genes for other major silk proteins, such asfibroin light chain andfibrohexamerin, were absent. This finding is consistent with previous reports that these latter proteins are lacking in saturniid silk. Recently, a series offibrohexamerin-like genes were identified in the Bombyx genome. We used this information to conduct a detailed analysis of the library established here. This analysis identified putative homologues of these genes. We also found several genes encoding small silk protein molecules that are also present in the silk of other Lepidoptera. Gene expression patterns were compared between eri and domestic silkworm, and both conserved and nonconserved expression patterns were identified for the tested genes. Such differential gene expression might be one of the major causes of the differences in silk properties between these species. We believe that our study can be of value as a basic catalogue for silk gland gene expression, which will yield to the further understanding of silk evolution.

Recently, development of high technology has been required for the formation of thin uniform film in manufacturing processes of semiconductor as the semiconductor instruments become more sophisticated. Spin coating is usually used for spreading photoresist on a wafer surface. However, since rotating speed of the disk is very high in spin coating, the dropped photoresist scarers outward and reattaches on the film surface. A catch cup is set up outside the wafer in spin coating, and scattered photoresist mist is removed from the wafer edge by the exhaust flow generated at the gap between the wafer edge and the catch cup. In the dry process of a spin coating, it is a serious concern that the film thickness increases near the wafer edge in the case of low rotating speed. The purpose of this study is to make clear the effect of the catch cup geometry on the 3D boundary layer flow over the wafer surface and the drying rate of liquid film.

WUSCHEL (WUS)是一种同源结构域转录因子，其作为WOX家族的一个进化分支，可能通过调节特定靶基因的表达，在植物细胞的胚胎发生和芽再生中发挥重要作用。本研究利用生物信息学方法在小麦(Triticum aestivum)的全基因组中一共鉴定出25个WUS基因，不均匀分布在第1、第2、第3和第5同源群染色体上，并且其在第3同源群染色体上发生了串联重复现象。保守结构域分析显示，该家族成员均含有motif 1和motif 3，基因结构和进化树显示，聚类在一起的WUS蛋白具有类似的基因结构。在TaWUSs的启动子区共鉴定出18类激素响应与非生物胁迫类的响应元件。组织表达谱分析显示，25个TaWUSs在小麦中拥有明显的组织表达特异性，且多数在花器官高表达。qRT-PCR结果进一步证实了TaWUS-2A1、TaWUS-3B2、TaWUS-3D2、TaWUS-5A1、TaWUS-5B1和TaWUS-5D1在正常雄蕊中高表达，而TaWUS-3D1在正常雌蕊中高表达。尤其是TaWUS-1A、TaWUS-1B、TaWUS-1D和TaWUS-2D1在雌蕊化雄蕊中高表达，预示其可能在调控小麦同源转化型雄性不育突变体(HTS-1)中雄蕊同源转化为雌蕊性状的形成中发挥作用。本研究为进一步解析小麦WUS亚家族基因的功能提供了理论基础。
