Species of the nitidulid beetle Conotelus found in flowers of Convolvulaceae and other plants across the New World and in Hawaii consistently harbour a yeast community dominated by one or more large-spored Metschnikowia species. We investigated the yeasts found in beetles and flowers of cultivated passionfruit in Rondônia state, in the Amazon biome of Brazil, where a Conotelus species damages the flowers and hinders fruit production. A sample of 46 beetles and 49 flowers yielded 86 and 83 yeast isolates, respectively. Whereas the flower community was dominated by Kodamaea ohmeri and Kurtzmaniella quercitrusa, the major yeasts recovered from beetles were Wickerhamiella occidentalis, which is commonly isolated from this community, and a novel species of large-spored Metschnikowia in the arizonensis subclade, which we describe here as Metschnikowia amazonensis sp. nov. Phylogenetic analyses based on barcode sequences (ITS-D1/D2) and a multigene alignment of 11,917 positions (genes ura2, msh6, and pmt2) agreed to place the new species as a sister to Metschnikowia arizonensis, a rare species known only from one locality in Arizona. The two form sterile asci when mated, which is typical of related members of the clade. The α pheromone of the new species is unique but typical of the subclade. The type of M. amazonensis sp. nov. is UFMG-CM-Y6309T (ex-type CBS 16156T , mating type a), and the designated allotype (mating type α) is UFMG-CM-Y6307A (CBS 16155A ). MycoBank MB 833560.

Conotelus sp。的酵母群落。巴西西番莲花(Passiflora edulis)中的鞘翅目(鞘翅目(Citioptera:Nitidulidae))和对墨西哥小球藻的描述。十一月,大孢子进化枝酵母。

在旋花科和整个新大陆以及夏威夷的其他植物的花朵中发现的甲虫科诺特人的一贯物种始终拥有一个由一个或多个大孢子菌组成的酵母群落。我们调查了巴西亚马逊河生物群区Rondônia州的百香果种植的甲虫和花朵中发现的酵母,Conotelus物种破坏了花朵并阻碍了果实的生产。46个甲虫和49朵花的样品分别产生了86和83个酵母菌。尽管花群落主要由小d科和库尔兹曼氏菌quercitrusa主导,但从甲虫中回收的主要酵母是西方的Wickerhamiella occidentalis,以及亚利桑那亚种中的一种新的大孢子菌Metschnikowia,在这里我们将其描述为马茨曼球菌(Metschnikowia amazonensis sp。)。十一月 基于条形码序列(ITS-D1 / D2)和11,917个位置的多基因比对(基因ura2,msh6和pmt2)的系统发育分析同意将新物种置于亚利桑那州Metschnikowia的姊妹物种中,Metschnikowia arizonensis是仅在一个地方已知的稀有物种在亚利桑那州。两者交配时会形成无菌腹水,这是进化枝相关成员的典型特征。新物种的α信息素是独特的,但是典型的。亚马逊分枝杆菌的类型 十一月 是UFMG-CM-Y6309T(ex型CBS 16156T,交配类型a),指定的同种异型(交配类型α)是UFMG-CM-Y6307A(CBS 16155A)。MycoBank MB 833560。和pmt2)同意将新物种作为亚利桑那州Metschnikowia arizonensis的姐妹,该物种仅在亚利桑那州的一个地方才知道。两者交配时会形成无菌的腹水,这是进化枝相关成员的典型特征。新物种的α信息素是独特的,但是典型的。亚马逊分枝杆菌的类型 十一月 是UFMG-CM-Y6309T(ex型CBS 16156T,交配类型a),指定的同种异型(交配类型α)是UFMG-CM-Y6307A(CBS 16155A)。MycoBank MB 833560。和pmt2)同意将新物种作为亚利桑那州Metschnikowia arizonensis的姐妹,该物种仅在亚利桑那州的一个地方才知道。两者交配时会形成无菌的腹水,这是进化枝相关成员的典型特征。新物种的α信息素是独特的,但是典型的。亚马逊分枝杆菌的类型 十一月 是UFMG-CM-Y6309T(ex型CBS 16156T,交配类型a),指定的同种异型(交配类型α)是UFMG-CM-Y6307A(CBS 16155A)。MycoBank MB 833560。指定的同种异型(交配型α)为UFMG-CM-Y6307A(CBS 16155A)。MycoBank MB 833560。指定的同种异型(交配型α)为UFMG-CM-Y6307A(CBS 16155A)。MycoBank MB 833560。
