It is caused by the fungus ''Gibberella fujikuroi'', the metabolism of which produces a surplus of gibberellic acid. In the plant, this acts as a growth hormone, causing hypertrophy. The afflicted plants, which are visibly etiolated and chlorotic, are at best infertile with empty panicles, producing no edible grains; at worst, they are incapable of supporting their own weight, topple over, and die (hence "foolish seedling disease"). The earliest known report of ''bakanae'' is from 1828; it was first described scientifically in 1898 by Japanese researcher Shotaro Hori, who showed that the causative agent was fungal.〔(A Short History of Gibberellins ) at Plant-Hormones.info〕 The fungus affects rice crops in Asia, Africa, and North America. In epidemic cases yield losses may reach up to 20% or more. A 2003 publication from the International Rice Research Institute estimated that outbreaks of bakanae caused crop losses that were 20% to 50% in Japan, 15% in Thailand and 3.7% in India. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bakanae」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
