A new and distinct variety of apple tree rootstock that exhibits compatibility with numerous apple varieties and resistance to Candidatus Phytoplasma mali and Athelia rolfsii.

The present invention relates to a hybrid between a leek and a garlic plant. More specifically, the invention relates to an interspecific hybrid plants resulting from a cross between an Allium ampeloprasum plant and an Allium sativum plant. Specifically, the present invention relates to Interspecific hybrid plants derived from a cross between an Allium ampeloprasum plant and an Allium sativum plant, wherein the hybrid plants are capable of producing seed and contains nuclear genomic material derived from both said Allium ampeloprasum plant and said Allium sativum plant, and further wherein the interspecific hybrid plants contain at least 250 mg/kg of allicin when determined in the white part of the leaf sheet of the plants and furthermore wherein the interspecific hybrid plants are obtainable, obtained or derived, from an interspecific hybrid plant as deposited under accession number NCIMB 42564.

The present invention relates to Apium graveolens plants being resistant to one or more genomically encoded resistances to the plant pathogen Septoria apiicola. Specifically the present invention relates to Apium graveolens plants wherein at least one genomically encoded resistance to the plant pathogen Septoria apiicola is the genomically encoded resistance to the plant pathogen Septoria apiicola as present in deposit NCIMB 42711. The present invention further relates to hybrids containing the present Septoria apiicola resistance and agents, as molecular markers, suitable for detecting the present invention.

The present invention provides transgenic carrot plants comprising at least one heterologous DNA sequence encoding: (a) a promoter of a transcription factor gene; or (b) a transcription factor geneoperably linked to a promoter; wherein the heterologous DNA sequence increases the expression of at least one gene encoding a sinapic acid glucosyltransferase (USAGT). The transcription factor gene is preferably DcMYB90 (SEQ ID NO:1) or DcEGL1 (SEQ ID NO:2) or a sequence having at least 80% identity to the sequence of SEQ ID NO:1 or at least 80% identity to the sequence of SEQ ID NO:2, wherein the sequence encodes a transcription factor protein increasing the expression of sinapic acid glucosyltransferase (USAGT) having the sequence of SEQ ID NO:4.

Rhizobial infection is the key process for initiating symbiotic nitrogen-fixing root nodules in legumes, which requires specific recognition of signal molecules produced by the bacteria and their hosts. Here, it is established that rhizobial tRNA-derived small RNA fragments (tRFs) are crucial signal molecules modulating host nodulation, which uncovers a bacterial small RNA-mediated mechanism for prokaryote-eukaryote interaction. Transgenic plants are also provided that express a construct encoding rhizobial-derived tRNA, which is subsequently cleaved to produce artificial tRFs. Constructs and methods of producing the same are also provided, as well as modifications for repressing a mechanism for the negative regulation of nodulation present within plants.

A new and distinct horseradish (Armoracia rusticana) named K-62 is disclosed, characterized by and distinguished from prior commercial horseradish varieties by increased activity of horseradish peroxidase (HRP). Plants have been clonally propagated by root division and shown to retain the increased HRP activity, which can be used, among other things, in molecular biology applications.

A new and distinct variety of Prunus rootstock tree that exhibits desirable disease resistance and induces a high yield of large fruits for grafted varieties.
