Facultative parthenogenesis in the Ryukyu drywood termite Neotermes koshunensis

Facultative parthenogenesis in the Ryukyu drywood termite Neotermes koshunensis
Parthenogenesis is a relatively rare reproductive mode in nature compared to sex. In social insects, the evolution of parthenogenesis has a notable impact on their life histories. Some termites with parthenogenetic ability produce numerous non-dispersing supplementary queens asexually, whereas other castes are produced via sexual reproduction.

Facultative parthenogenesis validated by DNA analyses in the green anaconda (Eunectes murinus)

Facultative parthenogenesis validated by DNA analyses in the green anaconda (Eunectes murinus)
In reptiles, the mode of reproduction is typically sexual. However, facultative parthenogenesis occurs in some Squamata, such as Komodo dragon (Varanus komodoensis) and Burmese python (Python bivittatus). Here, we report facultative parthenogenesis in the green anaconda (Eunectes murinus). We found two fully developed female neonates and 17 undeveloped

Discovery of facultative parthenogenesis in a new world crocodile

Biology Letters, 2023
Over the past two decades, there has been an astounding growth in the documentation of vertebrate facultative parthenogenesis (FP). This unusual reproductive mode has been documented in birds, non-avian reptiles—specifically lizards and snakes—and elasmobranch fishes.

Microarray analysis and PCR validation of genes associated with facultative parthenogenesis in Meleagris gallopavo (Turkey)

Theriogenology, 2022
A cDNA microarray containing 43,661 differentially expressed genes was carried out on the blastoderm of fertilized and facultative parthenogenic turkey embryos at different hours of development. The total number of up-regulated (UR) and down-regulated (DR) genes at 0, 12, and 24 h of development were 725 and 1436, 942 and 599, and 589 and 1044 ...

Facultative deuterotokous parthenogenesis in Callosobruchus maculatus

Zoologischer Anzeiger, 2021
Abstract The seed beetle, Callosobruchus maculatus (Coleoptera: Chrysomelidae), is a severe cosmopolitan pest of various stored legumes. Since no parthenogenesis has been reported in the genus Callosobruchus, here we report the evidence of a rare event of deuterotokous parthenogenesis in this species.

Facultative Parthenogenesis in Collembola (Insecta)

Nature, 1960
PARTHENOGENESIS in insects is well known, and its occurrence in the class is fairly widespread. In the order Collembola (the springtails) its presence has been suggested on rather disputable grounds and then afterwards denied on more than one occasion1.
