In this process, ancestral female\n                    <jats:italic toggle=\"yes\">C. elegans<\/jats:italic>\n                    acquired genetic modifications that enabled self-sperm generation, self-sperm activation and a reduced reliance on sexual reproduction. However, how males have adapted during this transition from dioecy to androdioecy is less explored. Using\n                    <jats:italic toggle=\"yes\">Caenorhabditis<\/jats:italic>\n                    species, we demonstrated that androdioecious hermaphrodites exhibit attenuated sex pheromone potency, while androdioecious males show heightened olfactory habituation and diminished mate exploration capabilities. The behaviour of androdioecious males can be reverted to resemble that of dioecious males by replacing the SRD-1 receptor with its dioecious orthologues. This intrinsic characteristic is contingent upon the C-terminal cytoplasmic domain of the receptor. We propose a theoretical framework where\n                    <jats:italic toggle=\"yes\">C. elegans<\/jats:italic>\n                    males have accumulated genetic variations in their pheromone receptor, leading to altered chemosensory perception of the opposite sex, which confers a selective advantage favouring hermaphroditism. Our study provides insights into overlooked male traits, shaped by changes in chemosensory signalling. The findings underscore the capacity of chemosensory variations to influence how organisms perceive critical ecological factors, eventually facilitating the emergence and stabilization of hermaphroditism.\n                  <\/jats:p>","DOI":"10.1098\/rsbl.2025.0239","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T23:05:56Z","timestamp":1758063956000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Chemosensory adaptations in\n                    <i>Caenorhabditis<\/i>\n                    males during the establishment of androdioecy"],"prefix":"10.1098","volume":"21","author":[{"given":"Harini","family":"Kannan","sequence":"first","affiliation":[{"name":"Division of Life Science, The Hong Kong University of Science and Technology","place":["Hong Kong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7722-813X","authenticated-orcid":true,"given":"King L.","family":"Chow","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2025,9,17]]},"reference":[{"key":"e_1_3_8_2_2","first-page":"346","article-title":"18S ribosomal RNA gene phylogeny for some Rhabditidae related to Caenorhabditis","volume":"12","author":"Fitch DH","year":"1995","unstructured":"Fitch DH, Bugaj-Gaweda B, Emmons SW. 1995 18S ribosomal RNA gene phylogeny for some Rhabditidae related to Caenorhabditis.
