“…This is plausible given that a similar process of gene loss may have occurred in the aflatoxin gene cluster (Carbone et al, 2007b). For example, putative heterothallic species A. flavus and A. parasiticus show striking variation in their chemotype profiles, some of which is directly attributable to gene loss (Chang et al, 2005;Ehrlich et al, 2004).…”

“…N. girellae also has a third N. girellae vasa -like gene ( Ngvlg3 ) that groups with vasa orthologues. This is noteworthy from a phylogenetic point of view since it has been proposed that monogeneans are basal to a clade composed of Classes Trematoda and Cestoda [11] and suggests that vasa orthologues had been lost in the common ancestor of flukes and tapeworms. However, transcripts encoding Ngvlg3 mRNA were not detectable while silencing Ngvlg3 did not affect gonad anatomy in the same fashion as silencing Ngvlg1 (PL10-like cluster) and Ngvlg2 [10].…”

How might flukes and tapeworms maintain genome integrity without a canonical piRNA pathway?

Surveillance by RNA interference is central to controlling the mobilization of transposable elements (TEs). In stem cells, Piwi argonaute (Ago) proteins and associated proteins repress mobilization of TEs to maintain genome integrity. This defense mechanism targeting TEs is termed the Piwi-interacting RNA (Piwi-piRNA) pathway. In this Opinion, we draw attention to the situation that the genomes of cestodes and trematodes have lost the piwi and vasa genes that are hallmark characters of the germline multipotency program. This absence of Piwi-like Agos and Vasa helicases prompts the question: how does the germline of these flatworms withstand mobilization of TEs? Here we present an interpretation of mechanisms likely to defend the germline integrity of parasitic flatworms.

Condition dependence of male and female reproductive success: insights from a simultaneous hermaphrodite

Sexually selected traits are predicted to show condition dependence by capturing the genetic quality of its bearer. In separate‐sexed organisms, this will ultimately translate into condition dependence of reproductive success of the sex that experiences sexual selection, which is typically the male. Such condition dependence of reproductive success is predicted to be higher in males than females under conditions promoting intense sexual selection. For simultaneous hermaphrodites, however, sex allocation theory predicts that individuals in poor condition channel relatively more resources into the male sex function at the expense of the female function. Thus, male reproductive success is expected to be less condition dependent than female reproductive success. We subjected individuals of the simultaneously hermaphroditic snail Physa acuta to two feeding treatments to test for condition dependence of male and female reproductive success under varying levels of male–male competition. Condition dependence was found for female, but not for male, reproductive success, meaning that selection on condition is relatively stronger through the female sex function. This effect was consistent over both male–male competition treatments. Decomposition of male and female reproductive performance revealed that individuals in poor condition copulated more in their male role, indicating an increased male allocation to mate acquisition. These findings suggest that sex‐specific condition dependence of reproductive success is at least partially driven by condition‐dependent sex allocation. We discuss the implications of condition‐dependent sex allocation for the evolution of sexually selected traits in simultaneous hermaphrodites.
