Embodiment 1

[0176] Example 1. Method of inducing plants to produce higher amounts of exudates or metabolites using divided roots.

[0177]In the split-root technique of the present invention, the two root systems of a plant are physically separated such that one root system (root A) can be stimulated and the root system induced systematically by either the stimulated root system (root A) or by the unaffected root system. The stimulated root system (root B) or both secrete valuable exudates or valuable metabolites or intermediates. In addition, the aerial parts of the same plants can be used as stimulation sites or alternatively as sites for harvesting metabolites after induction of the root system.

[0178] In this example, the root system of a seedling plant is divided into two equal parts, and each of the two root system parts is then placed in one of the two divided root compartments, each containing plant medium or direct In separate hydroponic or aeroponic containers, each feeds wit...

Embodiment 2

[0181] Example 2. Method of Inducing Plants to Produce Higher Amounts of Exudates or Metabolites Using Divided Roots Obtained by Regeneration

[0182] In the split-root technique of the present invention, the two root systems of a plant are physically separated such that one root system is stimulated (root A) and the secretion of valuable metabolites from the second root system (root B) is systematically induced. product. In addition, the aerial parts of the same plants can be used as stimulation sites or alternatively as sites for metabolite harvesting after induction of the root system. In addition, local induced secretion was also obtained from root A.

[0183] Divided roots are produced by cutting off the main root, then regenerating the lateral roots until they are long enough to place the lateral roots directly in individual hydroponic or aeroponic containers. Each container was fed with plant medium.

[0184] Following stimulation, the plants are incubated for the de...

Embodiment 3

[0186] Example 3: Method of inducing plants to produce higher amounts of exudates or metabolites using alternatively obtained divided roots.

[0187] In the split-root technique of the present invention, the two root systems of a plant are physically separated such that one root system (root A) is stimulated and systematically induced to secrete valuable metabolites from the second root system (root B). product. Additionally, the aerial parts of the same plants can be used as stimulation sites or alternatively as sites for metabolite harvesting after induction of the root system. In addition, local induced secretion was also obtained from root A.

[0188] The root structure is modified by one or more of various means to generate more root surface space, for example, by increasing branching or total root biomass. Root structure can be altered by one or more of: 1) genetic engineering; 2) genome editing; 3) chemical or radiation mutagenesis; 4) identification of natural variat...

Abstract

Provided is a plant exudate, methods for obtaining a plant exudate by inducing the plant to secrete an exudate and systems for the collection of a plant exudate which include: one or more plant container including at least two discrete compartments each configured to accommodate a split root of a plant, the compartments being a root stimulating compartment including one or more input being in fluid communication with at least a source of a plant root stimulant, and a root exudate harvesting compartment, and a root exudate collection compartment in fluid communication with the root exudate harvesting compartment.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Israeli Patent Application No. 258319, entitled "Method and System for Stimulating Root Exudation in Plants," filed March 22, 2018, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates to methods of inducing exudation of a plant by one or more compounds of interest, and to one or more novel compounds and combinations thereof. Background technique [0004] The plant kingdom produces thousands of different compounds, often genus or family specific. [0005] Some molecules are primary metabolites of plants, while others - known as secondary or "specific" metabolites - are not essential to the cells that produce them but contribute to the overall health of the organism. Alkaloids are an example of secondary metabolites. They are low molecular weight nitrogen-containing organic compounds, usually with a hete...
