Disclosed is a method for the production of a plant of the Cucurbitaceae family by mutating seeds to induce a mutation of 1-aminocyclopropane-1-carboxylate synthase 8 (ACS8) and growing a plant from the mutated seed, with the plant having a androecy or androecious tendency.

Methods of obtaining androecious cucurbit plants

Plants of the Cucurbitaceae family and seeds of such plants with an androecious phenotype, whereas this sexual type is not natural in the plants, and the use of the plants and of the plant seeds of the invention. Moreover, the nucleic acid sequence responsible for androecy in the plants of the invention and on the polypeptide encoded by the nucleic acid sequence. Finally, methods of identifying the plants and the seeds.

Androecious cucurbit plants, methods of obtaining and uses of said cucurbit plants

A genetic system for controlling the type of floral development of a dicotyledon plant, includes the combination of two genetic control elements, respectively:

Genetic system for controlling the floral development of a dicotyledon plant, and implementation in detection and selection processes

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: &#x2014;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.

eIF4E gene mutations and potyvirus resistance

The present invention relates to isolated Vat genes encoding a polypeptide that confers resistance toand/or resistance to viral transmission by aphids, and methods of transforming plant and cells with a Vat gene. The invention also relates to transgenic plants and cells having resistance toand/or resistance to viral transmission by aphids.
