Riboflavin induces resistance in rice against Rhizoctonia

Riboflavin-treatment of rice plants led to induction of resis-tance and suppression of disease progress was linked with lignin formation at the infection sites which was investigated using phloroglucinol/HCl test and thioglycolic-acid assay Expression of a cationic rice peroxidase (PO-C1) was examined using re-verse transcription-polymerase chain reaction (RT-PCR) Lignin formation that can

Development and characterization of an oat TILLING

Phloroglucinol/HCl staining of M3 seeds obtained from 1824 different M2 lines revealed a number of potential lignin mutants These were later confirmed by quantitative analysis Genomic DNA was prepared from the M2 population and the mutation frequency was determined The estimated mutation frequency was one mutation per 20 kb by RAPD-PCR fingerprinting one mutation per 38 kb by
