A method for producing lysophosphatidylethanolamine 18:1 includes extracting phospholipids including mainly phosphatidylethanolamine from a microorganism ofsp. and treating the extracted phospholipids with phospholipase A2. An alternative method for producing lysophosphatidylethanolamine 18:1 includes treating a microorganism ofsp. directly with phospholipase A2. The lysophosphatidylethanolamine 18:1 can be used as a plant vaccine material for preventing the plants from injuries caused by pathogen infections and/or environmental stresses and accelerating the recovery of plants injured by pathogen infections and/or environmental stresses, and can also be used as a composition for enhancing fruit ripening (color and sweetness) and storage properties, and as it can be used for an application in plant tissues, food products, pharmaceuticals, cosmetics, and agricultural use, it would be very advantageously used in related industries. This invention also provides a method of producing a phosphatidylethanolamine itself from a microorganism ofsp.

A method for increasing growth or biomass of a plant in a shorter period of time, compared to a control plant, includes transforming a plant cell using a recombination vector including a geranylgeranyl pyrophosphate synthase (GGPS) gene. A method for preparing a transgenic plant having higher growth or biomass in a shorter period of time, compared to a control plant, includes transforming a plant cell using the recombination vector having the GGPS gene. A composition for promoting higher growth or biomass of a plant, compared to a plant body, includes a GGPS gene. A plant or seed of the plant having higher growth or biomass, compared to the control plant, is prepared using the method.

GGPS gene for promoting higher growth or biomass of plant and use thereof

A laticiferous tissue-specific SRPP (small rubber particle-associated protein) promoter derived from, consists of nucleotide sequence of SEQ ID NO: 1. A recombinant plant expression vector includes the promoter. A plant is transformed with the recombinant plant expression vector and seed of the transformed plant is obtained. A method for laticiferous tissue-specific expression of a foreign gene in a transformed plant includes performing recombination of a foreign gene into the recombinant plant expression vector. The transformed plant produced by the method shows laticiferous tissue-specific expression of a foreign gene.

An isolated solely pollen-specific promoter derived fromcomprise a nucleotide sequence ofPLA-&#x3b4; gene. The novel promoter has specific roles in particular organs and at particular developmental stages, such as in mature flowers, and can be used in the production of hybrid seeds using male sterility techniques.
