Les choux-fleurs sont n茅s de la domestication des plantes par l鈥檋omme. Les chercheurs souhaitent comprendre comment ils adoptent diff茅rentes morphologies. Ici, on peut observer que la structure du chou est constitu茅e d鈥檜ne prolif茅ration de jeunes boutons floraux qui n鈥檃rrivent pas 脿 se diff茅rencier en fleurs. Ils d茅butent leur d茅veloppement comme des fleurs mais n鈥檃rrivent pas au stade final et continuent de prolif茅rer comme des tiges. Le chou fleur provient en effet d鈥檜ne modification de la tige portant des fleurs (inflorescence). Ceci renseigne les chercheurs sur le d茅veloppement normal des fleurs d鈥橝rabettes des dames, dites " mutants choux fleurs ".</p> </div> <div class="article-header-right"> <a href="/utilisateur/connexion?destination=/node/79491" class="wishlist-login" title="Me connecter pour ajouter 脿 ma s茅lection"><i class="icon icon--wishlist" aria-hidden="true" title=""></i> <span>Ajouter 脿 ma s茅lection</span> </a><div class="cart-link-wrapper"><a href="/order/add/79491?token=ezMUNdnQrHvs-JiM_HGAzKKIBtGlcrhTDNWe2A7Jf2k&destination=/photo/20170098_0006" aria-label="Ajouter au panier : Photo Chou-fleur observ茅 en microscopie 茅lectronique 脿 balayage" class="add-to-cart use-ajax action--add" data-type="image" data-ref="20170098_0006" rel="nofollow" role="button"><i class="icon icon--cart" aria-hidden="true" title=""></i> Ajouter au panier</a></div> <div class="link-cgu-wrapper"><a href="#_" class="btn btn-underline link-cgu" aria-describedby="media-cgu">Conditions d'utilisation</a><div role="tooltip" class="cgu cgu-closed" id="media-cgu"> <div class="field field--name-field-media-cgu field--type-text-long field--label-hidden field__item"><p><em>L鈥檜tilisation des m茅dias visibles sur la Plateforme CNRS Images peut 锚tre accord茅e sur demande.
