ANDROECIOUS CUCURBIT PLANTS, METHODS OF OBTAINING AND USES OF SAID CUCURBIT PLANTS

摘要

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.

主权项

1. A plant of the Cucurbitaceae family, which plant is:
selected among the group comprising the Cucumis, Citrullus, Cucurbita, Luffa, Momordica and Lagenaria genera, with the exclusion of the Cucumis sativus species; and characterised in that it comprises at least one allele of the non-encoding or encoding 1-aminocyclopropane-1-carboxylate synthase 8 (ACS8) for a polypeptide corresponding to a variant of the reference ACS8 for said plant, which reference 1-aminocyclopropane-1-carboxylate synthase 8 is encoded by a nucleic acid sequence corresponding to a dominant allele of ACS8 and has a transforming activity of the methionine S-adenosyl into aminocyclopropane carboxylate And said variant has a lower activity by at least 50%, preferably at least 75% or 90%, still more preferably 95% or 99% with respect to said reference 1-aminocyclopropane-1-carboxylate synthase 8 and particularly preferably, said variant has a nil activity.
