{"title":"Female heterogamety (ZW systems) in 22% of flowering plants with sex chromosomes: Theoretical expectations and correlates","authors":"Susanne S. Renner","doi":"10.1002/ajb2.70006","DOIUrl":"10.1002/ajb2.70006","url":null,"abstract":"&lt;p&gt;Genetic sex determination usually involves males and females that differ in their gametes, with one sex producing two types of gametes, the other a single type. When females produce two types, this is called female heterogamety and the sex chromosomes are denoted Z and W, while the reverse is male heterogamety, with the sex chromosomes denoted X and Y (Muller, &lt;span&gt;1915&lt;/span&gt;). Sex chromosomes can only occur in separate-sexed species, but inferring which sex is heterogametic can be difficult (Correns, &lt;span&gt;1917&lt;/span&gt;; Westergaard, &lt;span&gt;1958&lt;/span&gt;). Here I present a compilation of plant species with ZW sex chromosomes and briefly relate findings from plants to those from animals and to theoretical expectations about genetic degeneration and ecological correlates of female heterogamety. This seems relevant because theoretical studies are handicapped by the assumption that ZW sex chromosome systems are extremely rare (e.g., Marais and Lemaitre, &lt;span&gt;2022&lt;/span&gt;; Lesaffre et al., &lt;span&gt;2024&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;In land plants, female heterogamety is only known from flowering plants. This is surprising because almost half of all gymnosperms are dioecious (all 337 species of cycads, &lt;i&gt;Ginkgo bilob&lt;/i&gt;a, all 70 species of Gnetales, and a few conifers) and likely have sex chromosomes. In bryophytes, male or female heterogamety is not possible because the sexual generation is haploid, and unisexual plants thus have either a U or a V chromosome, but never both. Ferns and lycophytes have few sexually specialized species (Renner, &lt;span&gt;2014&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Female heterogamety was discovered in chickens and a magpie moth (Muller, &lt;span&gt;1915&lt;/span&gt;), and today we know that this type of sex determination characterizes most birds (10,000 species), butterflies and moths (perhaps 180,000 species), snakes (perhaps 4000 species), and many fish and amphibians. Some fish, such as &lt;i&gt;Xiphophorus maculatus&lt;/i&gt;, have strains in which the females are the heterogametic sex and others in which the males are heterogametic (Kallman, &lt;span&gt;1965&lt;/span&gt;). Frog species also can have W, Z, and Y sex chromosomes in different populations (e.g., Ezaz et al., &lt;span&gt;2006&lt;/span&gt;; Furman et al., &lt;span&gt;2020&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;The first plant ZW systems were inferred at the same time as those in animals, using experimental interspecific crossings and resulting sex ratios, not microscopy. These first experiments focused on &lt;i&gt;Fragaria chiloensis&lt;/i&gt; and &lt;i&gt;F. virginiana&lt;/i&gt; (Muller, &lt;span&gt;1915&lt;/span&gt; interpreting experiments by Richardson, &lt;span&gt;1914&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;My compilation (Table 1) updates a database of green plants with sex chromosomes that includes 124 angiosperms with male heterogamety and 33 with female heterogamety (Garcia et al., &lt;span&gt;2023&lt;/span&gt;). These lists of ZW species differ because of corrections and additions, which are coming rapidly because of genomic research.
