Quelque part sur un spectre qui comprend l'attraction gravitationnelle des mar\u00e9es oc\u00e9aniques et les transformations des loups-garous, il semble que les plants de caf\u00e9 soient \u00e9galement \u00e9trangement affect\u00e9s par le cycle lunaire.<\/p>\n

La premi\u00e8re \u00e9tude du genre r\u00e9alis\u00e9e par le Cirad, un organisme \u00e0 but non lucratif agricole fran\u00e7ais – qui effectue des tonnes de travaux int\u00e9ressants dans le secteur du caf\u00e9 – a r\u00e9v\u00e9l\u00e9 que le clair de lune a la capacit\u00e9 de perturber l'horloge circadienne des plants de caf\u00e9. En d'autres termes, la lune perturbe le sommeil du caf\u00e9.<\/p>\n

Dans l'\u00e9tude, r\u00e9cemment publi\u00e9e dans la revue en libre acc\u00e8s BMC Plant Biology, les auteurs du Cirad sugg\u00e8rent que les effets au niveau mol\u00e9culaire du clair de lune sur les plants de caf\u00e9 pourraient inciter les producteurs de caf\u00e9 \u00e0 en prendre note.<\/p>\n

\u00abNotre analyse des g\u00e8nes diff\u00e9rentiellement r\u00e9gul\u00e9s semble montrer que les caf\u00e9iers voient le clair de lune comme une forme de stress\u00bb, a d\u00e9clar\u00e9 Jean-Christophe Breitler, g\u00e9n\u00e9ticien du Cirad bas\u00e9 au Mexique dans une annonce de l'\u00e9tude. "Il perturbe non seulement les g\u00e8nes de l'horloge circadienne, mais aussi de nombreux autres contr\u00f4l\u00e9s par eux, tels que les g\u00e8nes li\u00e9s \u00e0 la photosynth\u00e8se, la biosynth\u00e8se des lipides, le contr\u00f4le de la croissance et la r\u00e9ponse au stress oxydatif et thermique."<\/p>\n

Le rapport note qu'un tel stress peut en fait avoir des effets positifs sur la croissance des plantes, bien que trop peu de recherches aient \u00e9t\u00e9 faites sur le sujet pour tirer de nombreuses conclusions fermes.<\/p>\n

L'\u00e9quipe de recherche du Cirad elle-m\u00eame est devenue curieuse des effets du clair de lune sur les plants de caf\u00e9 tout en menant une \u00e9tude distincte sur la mani\u00e8re dont les changements climatiques peuvent \u00eatre li\u00e9s aux mod\u00e8les circadiens des plants d'arabica. L'\u00e9quinoxe de printemps a apport\u00e9 une pleine lune aux plantes \u00e0 l'\u00e9tude dans une serre, et les chercheurs ont ensuite recr\u00e9\u00e9 le clair de lune – une r\u00e9flexion de bas niveau de la lumi\u00e8re du soleil – tout en \u00e9tudiant des plantes priv\u00e9es de clair de lune.<\/p>\n

Au sujet des plantes au clair de lune, Breitler a d\u00e9clar\u00e9: \u00abCe que nous avons d\u00e9couvert, c'est que les photor\u00e9cepteurs des plantes consid\u00e9raient ces longueurs d'onde de faible intensit\u00e9 comme de forts signaux environnementaux.\u00bb<\/p>\n
