“…Recent studies based on genome sequencing revealed the presence of foreign DNA sequences in the genetic material of several species of Lepidoptra [ 44 ]. Indeed, pro- and eukaryotic genes that moved through the horizontal gene transfer are expressed in such insect genomes [ 45 ]. Hence, it might be speculated that progenitors of Dhb and T. molitor have acquired foreign DNA encoding hyperactive AFP through unrevealed gene transfer mechanism mediated by an organism, despite Blast searches not showing any sign of hyperactive AFP synthesis in plants, fungi, nor bacteria DNA.…”

Beetle hyperactive antifreeze protein (AFP) has a unique ability to maintain a supercooling state of its body fluids, however, less is known about its origination. Here, we found that a popular stag beetle Dorcus hopei binodulosus (Dhb) synthesizes at least 6 isoforms of hyperactive AFP (DhbAFP). Cold-acclimated Dhb larvae tolerated −5 °C chilled storage for 24 h and fully recovered after warming, suggesting that DhbAFP facilitates overwintering of this beetle. A DhbAFP isoform (~10 kDa) appeared to consist of 6−8 tandem repeats of a 12-residue consensus sequence (TCTxSxNCxxAx), which exhibited 3 °C of high freezing point depression and the ability of binding to an entire surface of a single ice crystal. Significantly, these properties as well as DNA sequences including the untranslated region, signal peptide region, and an AFP-encoding region of Dhb are highly similar to those identified for a known hyperactive AFP (TmAFP) from the beetle Tenebrio molitor (Tm). Progenitor of Dhb and Tm was branched off approximately 300 million years ago, so no known evolution mechanism hardly explains the retainment of the DNA sequence for such a long divergence period. Existence of unrevealed gene transfer mechanism will be hypothesized between these two phylogenetically distant beetles to acquire this type of hyperactive AFP.

“…HGT has recently been proposed as a potential explanation for the presence of very similar AFPs in two distantly related coleopteran taxa ( Arai et al 2021 ). In insects, virus-mediated gene transfer between species has been well documented ( Gilbert et al 2016 ), sometimes involving portions of DNA large enough to harbor genes such as those encoding AFPs (see Drezen et al 2017 ; Zakharov 2016 ). With such HGTs, however, one would also expect significant intronic similarity between AFP genes in the two species, particularly if the transfer were relatively recent ( Graham et al 2012 ), which does not seem to be the case here (i.e.…”

Insects have developed various adaptations to survive harsh winter conditions. Among freeze-intolerant species, some produce “antifreeze proteins” (AFPs) that bind to nascent ice crystals and inhibit further ice growth. Such is the case of the spruce budworm, Choristoneura fumiferana (Lepidoptera: Tortricidae), a destructive North American conifer pest that can withstand temperatures below -30°C. Despite the potential importance of AFPs in the adaptive diversification of Choristoneura, genomic tools to explore their origins have until now been limited. Here we present a chromosome-scale genome assembly for C. fumiferana, which we used to conduct comparative genomic analyses aimed at reconstructing the evolutionary history of tortricid AFPs. The budworm genome features 16 genes homologous to previously reported C. fumiferana AFPs (CfAFPs), 15 of which map to a single region on chromosome 18. Fourteen of these were also detected in five congeneric species, indicating Choristoneura AFP diversification occurred before the speciation event that led to C. fumiferana. Although budworm AFPs were previously considered unique to the genus Choristoneura, a search for homologs targeting recently sequenced tortricid genomes identified seven CfAFP-like genes in the distantly related Notocelia uddmanniana. High structural similarity between Notocelia and Choristoneura AFPs suggests a common origin, despite the absence of homologs in three related tortricids. Interestingly, one Notocelia AFP formed the C-terminus of a “zonadhesin-like” protein, possibly representing the ancestral condition from which tortricid AFPs evolved. Future work should clarify the evolutionary path of AFPs between Notocelia and Choristoneura and assess the role of the “zonadhesin-like” protein as precursor of tortricid AFPs.

“…However, even genes successfully transmitted and integrated into an organism are not necessarily transcribed in the recipient cell(Nikoh et al 2008). A few instances of HGT involving retroelements of plants and arthropods are known, involving genomic elements from arthropods to spermatophytes(Lin et al 2016, Gao et al 2018, as well as from plants or fungi into arthropods (e.g.,Moran & Jarvik 2010, Altincicek et al 2012, Zakharov 2016.…”

We address and discuss some of the many fl aws exhibited by Costa et al. (2019) which tried to explain the twig-like camoufl age of Cladomorphus phyllinus. Given the lack of both empirical and theoretical underpinnings in Costa et al. ( 2019), we call into question the validity of their conclusions, in particular, that horizontal gene transfer is a causal mechanism for the camoufl age in C. phyllinus.
