Genome size and chromosome number of five Cimicidae species were compared with the similar data recently received from Cimex lectularius parasitizing human. The average nuclear DNA content (males) was 2C = 1.47 pg in C. hemipterus, 2C = 1.61 pg in C. hirundinis, 2C = 1.80 pg in C. lectularius from bats, 2C = 1.68 pg in C. pipistrelli, and 2C = 1.22 pg in Paracimex cf. chaeturus. In the genomes of all cimicid species analyzed, the average GC content ranged from 32.74% in C. pipistrelli to 35.87% in P. cf. chaeturus. Chromosome variability with two male cytotypes, 2n = 28 + X1 X2 Y and 28 + X1 X2 X3 Y, was confirmed in C. pipistrelli. In addition, intraspecific variability in chromosome number was revealed in C. lectularius from bats with 2n = 26 + X1 X2 Y and 26 + X1 X2 X3 Y. We suggest that the origin of intraspecific variability in chromosome number of C. lectularius from bats and C. pipistrelli is not only the result of simple fragmentation, but additive rearrangements like duplications are probably also involved. © 2019 International Society for Advancement of Cytometry.

臭虫摄食动物宿主的基因组大小和性别染色体变异性与Cimex lectularius寄生人类(异翅目:Cimicidae)相比。

比较了五个昆虫科物种的基因组大小和染色体数,并将其与最近从寄生人的Cimex lectularius收到的类似数据进行了比较。半翅目鱼的平均核DNA含量(雄性)为2C = 1.47 pg,hirundinis中的2C = 1.61 pg,蝙蝠的C. lectularius中的2C = 1.80 pg,pipistrelli的2C = 1.68 pg,2C =在Paracimex中为1.22 pg cf. 牧羊人。在所分析的所有杀螨物种的基因组中,平均GC含量范围从C. pipistrelli的32.74%到P. cf.的35.87%。牧羊人。在pipistrelli中证实了具有两种雄性细胞型2n = 28 + X1 X2 Y和28 + X1 X2 X3 Y的染色体变异性。另外,在来自2n = 26 + X1 X2 Y和26 + X1 X2 X3 Y的蝙蝠的C. lectularius中揭示了染色体数的种内变异性。我们建议蝙蝠和C. pipistrelli的C. lectularius染色体数目的种内变异性的起源不仅是简单片段化的结果,而且还可能涉及重复的加性重排。©2019国际细胞计数学会。
