Thus, we define the interplay between the expression of CYC2-like genes and the phyllotactic mechanisms.\u003c\/p\u003e \u003cp\u003eThis new evo-devo approach is applied to major groups of angiosperms with predominantly actinomorphic flowers (in which rare zygomorphy is positional) and groups with mainly bilaterally symmetrical flowers (in which zygomorphy is constitutional). It has thus allowed us to revisit the contributions of the great floral morphologists of the 20th and early 21st centuries.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Jean-Paul Walch, Solange Blaise\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1786309890\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781786309891\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Wiley-Iste\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/13\/2024\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 256\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.14lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.56d","brand":"Jean-Paul Walch","offers":[{"title":"Hardcover","offer_id":46401594622207,"sku":"9781786309891","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_b1370c54-8ebc-4a5a-9ebd-882993fbecf7.jpg?v=1733888069","url":"https:\/\/www.whiterainbookhouse.com\/products\/phyllotaxis-and-symmetry-in-angiosperms-jean-paul-walch-9781786309891","provider":"WR Book House","version":"1.0","type":"link"}
