    • Provided are isolated nucleic acid molecules which comprise VRN1 nucleotide sequences, which encode a polypeptide which is capable of specifically altering the vernalisation response of a plant into which the nucleic acid is introduced and expressed. Examples include cDNA and gDNA sequences (see e.g., Annex I). Also provided are variant molecules which may be derivatives or homologues (e.g., alleles, or paralogues such as RTV1), plus also complementary molecules. Corresponding polypeptides form a further part of the invention. The invention also provides methods and materials for preparing and using these molecules, e.g., in the production of plants having modified vernalisation characteristics. Also provided are methods for influencing and assessing the vernalisation phenotype of a plant.
    • 提供了包含VRN1核苷酸序列的分离的核酸分子,其编码能够特异性改变引入和表达核酸的植物的春化反应的多肽。 实例包括cDNA和gDNA序列(参见例如附录I)。 还提供了可以是衍生物或同系物(例如等位基因或旁系同源物,例如RTV1)的变体分子,以及互补分子。 相应的多肽构成本发明的另一部分。 本发明还提供了用于制备和使用这些分子的方法和材料,例如在具有改性的春化特性的植物的生产中。 还提供了影响和评估植物的春化表型的方法。
