The compositions can be used in, for example, plant growth regulation and weed control, including controlling the germination of parasitic root plants, inhibiting rice tillering, and triggering leaf senescence.

Strigolactone analogs and their usage in plant control

This invention relates to an agent for inducing a callus comprising a compound represented by Formula (I) or a hydrolysis product of an amide bond thereof: wherein Arrepresents phenyl substituted with substituent or substituents selected from alkoxy and methylenedioxy; Arrepresents phenyl substituted with halogen; Rand Reach represent hydrogen, alkyl, cyano, or carboxyl; Rand Rmay together form oxo; Rto Reach represent hydrogen or methyl; and Rand R, Rand R, Rand R, and/or Rand Rmay together form oxo; a method for inducing a callus and a method for plant transformation using such agent for inducing a callus.

Agent for inducing callus and method for inducing callus

An object of the present invention is to identify a novel gene that effectively increases plant biomass and to provide said gene as well as techniques utilizing the same. This invention provides a nucleic acid encoding a protein, wherein the protein comprises the amino acid sequence of SEQ ID NO:1 and an amino acid sequence having at least 25% identity or at least 75% similarity to the amino acid sequence of SEQ ID NO:7 or 11, and has an activity to increase plant biomass, as well as techniques utilizing the same.

Gene for increasing plant biomass and use therefor

The present invention concerns: a plant growth-promoting agent comprising a compound represented by Formula (I) or a salt thereof:  wherein Arrepresents a substituted or unsubstituted phenyl group, NZ represents a nitrogen-containing heterocyclic ring group or an acyclic nitrogen-containing group having a partial structure of the nitrogen-containing heterocyclic ring group, n is 0, 1, or 2, Rand Reach represent a hydrogen atom, a substituted or unsubstituted C-alkyl group, a cyano group, or a carboxyl group, Rand Rmay together form an oxo group, and when n is 2, Ror Rmay be the same or different; and a method for promoting plant growth using the plant growth-promoting agent.

Plant growth-promotion agent and method for promoting plant growth

According to the present invention, a transgenic plant, wherein expression of the BSS1 gene having activity to bind to a BIL1 protein to inhibit the transfer of the BIL1 protein into the nucleus so as to down-regulate brassinosteroid signaling is suppressed or promoted, and a method for regulating plant growth, wherein expression of the BSS1 gene in a plant body is suppressed or promoted, are provided.

Method for regulating plant growth

An object of the present invention is to provide an auxin biosynthesis inhibitor superior to L-AOPP. The object can be attained by a compound represented by general formula (I): wherein, Rto Rand X are the same as defined in the specification or a salt or solvate thereof. 

Auxin biosynthesis inhibitor
