Phylogenetic analysis on coevolution between Leguminous plants and their parasites/mutualists.

岛田和伊藤指导研究生加藤从每年的12月到3月在墨西哥进行了几次海外调查。他们对墨西哥的豆象昆虫进行了分子系统发育分析，以研究宿主植物的特化/泛化。一般来说，进化昆虫学家通常认为植食性昆虫在适应寄主植物的过程中发生了从杂食到寡食的进化。然而，当我们检查了属Mimosestes的寄生性，一个组（M。amicus、M. insularis、M.含羞草属植物（mimosae）已经从一个专家进化为一个具有更广泛的寄主植物食谱的多面手。此外，Shimada和Hidzwarta对从沃尔巴克氏体水平传递到红豆甲虫C. Tuda研究了豆象种子捕食者寄主植物的进化转移。她指出，饮食转向干燥成熟的种子在属，Callosobruchus，已经演变成 关于我们 根据最大似然概率，Bruchidius和Bruchus对寄主豆科植物表现出保守的使用，她指出这两个属很可能将其寄主范围扩大到相思属豆科植物。此外，Tuda还与Hangarian合作者合作，在海外进行了调查，研究在中东欧有专门饮食的豆象种子甲虫。Toquenaga在每年2月和3月进行海外调查，从市场上交易的感染性种子中收集萌发的豆象种子甲虫。他研究了C语言中的造墙行为和竞争/争夺竞争类型。为了研究它们在品系内/品系之间的遗传变异，此外，他们还拜访了英国合作者，并获得了几株C。揭示了C. maculates和C.这是在以前的文章中提出的肛门。少

Shimada and Ito supervised a graduate student, Kato, to make a few oversea surveys in Mexico from December to March every year. They conducted molecular phylogenetic analyses on Bruchid insects in Mexico in order to study specialization/generalization of host plants. In general, evolutionary entomologists usually consider that a phytophagous insect changes evolutionally from polyphagy to oligophagy when they adapt to the host plants. However, when we examined the phylogenies of the genus Mimosestes, a group (M. amicus, M. insularis, M. mimosae) has evolved from a specialist to a generalist with wider diets of host plants. In addition, Shimada and Hidzume conducted a genomic analysis on a Wolbachia DNA region that was transmitted horizontally from Wolbachia to X-chromosome of the azuki bean beetle, C. chinensis.Tuda studied the evolutionary shift of host plants in the bruchid seed predators. She showed that dietary shift to dried-matured seeds in the genus, Callosobruchus, has evolved w … More ith longer dry season, based on their maximum likelihood phylogenies. Bruchidius and Bruchus showed conservative usage for host legumes, and she pointed out that the two genera were likely to expand their host range to Acacia legumes. In addition, Tuda had oversea surveys to study bruchid seed beetles that have a specialist diet in mid-eastern Europe in collaboration with Hangarian cooperators. They examined concordance between the molecular phylogenies and several categories of host traits and concluded that the most concordant character was chemical poisonous substances.Toquenaga had oversea surveys in every February and March and collected emergent bruchid seed beetles from infectious seeds that were traded in markets there. He studied the wall-making behavior and the contest/scramble competition type in C. maculates in order to study their genetic variation within/between strains. In addition, they visited English cooperators and were given several strains of C. maculates to reveal hybridization possibility between C. maculates and C. analis that had been suggested in previous articles.
