2021 NEW BOOK CHAPTER on Microbial Cell Communication
Book Chapter Paz-y-Miño-C, G. Espinosa, A., 2021. The Many Shapes of Microbial Detection of Kin and Kind. Pp. 79-99. In: G. Chapouthier & MC Maurel (Eds.) The Explosion of Life Forms: Living Beings and Morphology. Wiley-ISTE, London, UK. ISBN (10): 1789450055, ISBN (13): 978-1789450057.
Chapter 6. The Many Shapes of Microbial Detection of Kin and Kind by Guillermo PAZ-Y-MIÑO-C and Avelina ESPINOSA – Bacteria, archaea and protists are anatomically/functionally equipped to detect close genetic relatives, as well as distantly related conspecifics. In this chapter, the authors discuss the adaptive value of a microbe’s ability to discriminate/recognize kin from non-kin. Because the theoretical framework of this field was initially developed for animals – and some plants, they first explain its foundations and later examine unicells’ examples. Emphasis is on “shapes” and genetics. The authors highlight the relevance of kin detection for altruistic cooperation (including among pathogens) or for the identification of “cheater cells” (the beneficiaries of others’ selfless acts, but that do not contribute to the collective well-being), and for the formation of temporary or permanent cell alliances, which are informative for understanding the evolutionary origins of multicellularity.

Biology of ADHE enzymes

2 (EhADH2). The enzymatic activities reside in two separate, interacting domains: aldehyde dehydrogenase (ALDH) and alcohol dehydrogenase (ADH) between domains (Paz-y-Mino-C & Espinosa 2010) |
Books
April 2018: Kin Recognition in Protists and Other Microbes is the first volume dedicated entirely to the genetics, evolution and behavior of cells capable of discriminating and recognizing taxa (other species), clones (other cell lines) and kin (as per gradual genetic proximity).
