   Abstract By introducing novel capacities and functions, new genes and gene families may play a crucial role in ecological transitions. Mechanisms generating new gene families include de novo gene birth, horizontal gene transfer, and neofunctionalization following a duplication event. The ectomycorrhizal (ECM) symbiosis is a ubiquitous mutualism and the association has evolved repeatedly and independently many times among the fungi, but the evolutionary dynamics enabling its emergence remain elusive. We developed a phylogenetic workflow to first understand if gene families unique to ECM Amanita fungi and absent from closely related asymbiotic species are functionally relevant to the symbiosis, and then to systematically infer their origins. We identified 109 gene families unique to ECM Amanita species. Genes belonging to unique gene families are under strong purifying selection and are upregulated during symbiosis, compared with genes of conserved or orphan gene families. The origins of seven of the unique gene families are strongly supported as either de novo gene birth (two gene families), horizontal gene transfer (four), or gene duplication (one). An additional 34 families appear new because of their selective retention within symbiotic species. Among the 109 unique gene families, the most upregulated gene in symbiotic cultures encodes a 1-aminocyclopropane-1-carboxylate deaminase, an enzyme capable of downregulating the synthesis of the plant hormone ethylene, a common negative regulator of plant-microbial mutualisms.

4. Disassembling cattle and enskilling subjectivities: Butchering techniques and the emergence of new colonial subjects in Santiago de Guatemala

   When they introduced cattle into Guatemala in the 16th century, Europeans also brought a whole new industry involving ranches, slaughterhouses, and new forms of labor. On the one hand, cattle producers had to treat the animals as intact living organisms requiring care and nurture to maintain and increase the herds. Those animals were grown by the ranchers for specific purposes. In the first place, colonial Mesoamerican cattle were raised to produce hides and leather for intercontinental trade with Spain. The regularized disassembling of the bovine bodies created these new products, but it also had some unintended consequences, namely the generation of new subject positions among the indigenous workers of these facilities. New forms of butchering techniques aimed at extracting animal parts were unlike the indigenous practices of animal hunting and exploitation, which aimed at preserving the physical integrity of the animals’ bodies. The newly introduced techniques that involved the compartmentalization of animal bodies also involved an increased compartmentalization of labor, accompanied by new body techniques and gestures. As the butchers and the tanners became enskilled, their bodies changed and so did their hexis. To operationalize these ideas, technological approaches combined with zooarchaeological (butchery marks), ethnographic, and historical evidence are used to investigate how humans and cattle mutually grew each other’s matter and subjectivities.
