  • Photosynthetic organisms through the modulation of guanosine tetraphosphate homeostatis
    Patent number: 11104913
    Abstract: The present invention concerns methods and approaches for modifying guanosine tetraphosphate (ppGpp) homeostasis in photosynthetic eukaryotes, in particular plants or algae, in order to modulate senescence for the remobilisation of nitrogen and other nutrients from the chloroplast, and modified photosynthetic eukaryotes thus produced.
    Type: Grant
    Filed: February 7, 2017
    Date of Patent: August 31, 2021
    Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS), UNIVERSITÉ D'AIX MARSEILLE

  • eIF4E gene mutations and potyvirus resistance
    Patent number: 7919677
    Abstract: The invention concerns a method for obtaining potyvirus resistant plants exhibiting one or several mutations in a preserved region of the eIF4E translation factor, defined by the following general sequence (I): DX1X2X3X4KSX5QX6AWGSSX7RX8X9YTFSX10VEX11FWX12X13YNNIHX14P SKLX15X16GAD wherein: —X1, X2, X3, X4, X6, X7, X8, X9, X10, X12, X13, X15, et X16 represent each a neutral amino acid; X5 and X14 represent a basic amino acid; X11 represents an acid amino acid; D, K, S, Q, A, W, G, R, Y, T, F, V, E, N, I, H, P, and L have their usual one-letter code meaning.
