PROBLEM TO BE SOLVED: To provide a plant which suppresses expression of a gene which functions in vesicular transport in plant cells, or in which functions of a protein encoded by the gene are inhibited.SOLUTION: The invention relates to a plant in which expression of a gene encoding a coatomer adapter zeta subunit is suppressed or the coatomer adapter zeta subunit is inhibited, or in which expression of a gene encoding a clathrin adaptor small (sigma) subunit is suppressed or the clathrin adaptor small (sigma) subunit is inhibited. The invention also relates to a method for increasing plant biomass production and a method for producing a plant capable of producing increased biomass by suppressing expression of the gene by RNA interference. 【課題】植物細胞内の小胞輸送で機能する遺伝子の発現を抑制する又は当該遺伝子がコードするタンパク質の機能を阻害した植物体の提供。【解決手段】コートマー・アダプタのゼータサブユニットをコードする遺伝子の発現を抑制する又はコートマー・アダプタのゼータサブユニットを阻害する、若しくはクラスリン・アダプタの小（シグマ）サブユニットをコードする遺伝子の発現を抑制する又はクラスリン・アダプタの小（シグマ）サブユニットを阻害した植物体。当該遺伝子の発現をＲＮＡ干渉法により抑制することによるバイオマス量を増産する方法、バイオマス量が増産した植物体の製造方法。【選択図】図３
