Description:
Some ferns possess the ability to control their sex ratio to maintain genetic variation in their colony with the aid of antheridiogen pheromones, antheridium (male organ)-inducing compounds that are related to gibberellin. We determined that ferns have evolved an antheridiogen-mediated communication system to produce males by modifying the gibberellin biosynthetic pathway, which is split between two individuals of different developmental stages in the colony. Antheridiogen acts as a bridge between them because it is more readily taken up by prothalli than bioactive gibberellin. The pathway initiates in early-maturing prothalli (gametophytes) within a colony, which produce antheridiogens and secrete them into the environment. After the secreted antheridiogen is absorbed by neighboring late-maturing prothalli, it is modified in to bioactive gibberellin to trigger male organ formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, Junmu -- Yano, Kenji -- Aya, Koichiro -- Hirano, Ko -- Takehara, Sayaka -- Koketsu, Eriko -- Ordonio, Reynante Lacsamana -- Park, Seung-Hyun -- Nakajima, Masatoshi -- Ueguchi-Tanaka, Miyako -- Matsuoka, Makoto -- New York, N.Y. -- Science. 2014 Oct 24;346(6208):469-73. doi: 10.1126/science.1259923.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bioscience and Biotechnology Center, Nagoya University, Nagoya 464-8601, Japan. ; Department of Applied Biological Chemistry, University of Tokyo, Tokyo 113-8657, Japan. ; Bioscience and Biotechnology Center, Nagoya University, Nagoya 464-8601, Japan. mueguchi@nuagr1.agr.nagoya-u.ac.jp makoto@nuagr1.agr.nagoya-u.ac.jp.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25342803" target="_blank"〉PubMed〈/a〉
