Rice (Oryza sativa L.) phloem sieve tubes contain RPP13-1, a thioredoxin h protein that moves around the plant via the translocation stream. Such phloem-mobile proteins are thought to be synthesized in the companion cells prior to being transferred, through plasmodesmata, to the enucleate sieve-tube
OBJECTIVE
Pathogenicity of Exobasidium vexans, causal agent of blister blight of tea, was studied in 30 commercially cultivated tea varieties by analysing the antigenic patterns of host and pathogen using immunological techniques.
RESULTS
Whole plant inoculation of tea varieties with E. vexans
N1-Phenyl-N3-aryl/aryloxymethyl[1,3,4-oxa(thia)diazol-2-yl]s ulphonyl ureas (4 and 7) were conveniently prepared from 2-aryl/aryloxymethyl- 1,3,4-oxa(thia)diazol-2-sulphonamide (3 and 6) and phenyl isothiocyanate. Sulphonamides were synthesised by the reaction of
Brassicaceae plants rich in glucosinolates have been used as biofumigants for management of Rhizoctonia solani (teleomorph: Thanatephorus cucumeris) and other soilborne pathogens. Efficacy of brassica plant tissue has mainly been attributed to toxic isothiocyanates released upon hydrolysis of
