The cultivation of rice in Japan has suffered from damage caused by baka nae disease, in which rice seedlings show abnormal growth (elongation) as the result of infection by a plant pathogen. Investigation of the taxonomy of this pathogen led to th

Whether 3-epigibberellin(3-epiGA1) is endogenous in plants or is formed from GA1 as an artefact, can be determined by adding [13C]GA1 to the plant material as an internal reference and measuring the 12C:13C ratio of 3-epiGA1 and GA1, recovered from t
