Novel species of Calonectria associated with Eucalyptus leaf blight in Southeast China
Leaf blight caused by Calonectria spp. is an important disease occurring on Eucalyptus trees grown in plantations of Southeast Asia. Symptoms of leaf blight caused by Calonectria spp. have recently been observed in commercial Eucalyptus plantations in FuJian Province in Southeast China. The aim of this study was to identify these Calonectria spp. employing morphological characteristics, DNA seq...
متن کاملCalonectria species associated with cutting rot of Eucalyptus
Decline in the productivity of Eucalyptus hybrid cutting production in the Guangdong Province of China is linked to cutting rot associated with several Calonectria spp. The aim of this study was to identify these fungi using morphological and DNA sequence comparisons. Two previously undescribed Calonectria spp., Ca. pseudoreteaudii sp. nov. and Ca. cerciana sp. nov. were identified together wit...
متن کاملMapping and validation of QTLs for rice sheath blight resistance
Sheath blight, caused by Rhizoctonia solani, is one of the most serious diseases of rice. Among 33 rice accessions, mainly from National Institute of Agrobiological Sciences (NIAS) Core Collection, we found three landraces from the Himalayas-Jarjan, Nepal 555 and Nepal 8-with resistance to sheath blight in 3 years' field testing. Backcrossed inbred lines (BILs) derived from a cross between Jarj...
متن کاملDiversity and potential impact of Calonectria species in Eucalyptus plantations in Brazil.
Species in the genus Calonectria (Hypocreales) represent an important group of plant pathogenic fungi that cause serious losses to plant crops in tropical and subtropical climates. Calonectria leaf blight is currently one of the main impediments to Eucalyptus cultivation in Brazil, and various species of Calonectria have been associated with this disease. Since most previous identifications wer...
متن کاملMicrobial conversion of partheniol by Calonectria decora.
The biotransformation of partheniol by the fungus Calonectria decora ATCC 14767, produced six metabolites. These metabolites are; aromadendr-1(10)-en-8alpha -ol; 5(9),6-tricyclohumul-1(10)-en-8alpha-ol; 4,15-didehydro-6-bicyclohumulan-8a,10alpha-diol; 5(9),6-tricyclohumulan-4a,8alpha-diol; maalian-la,8alpha-diol and 14-epi-1(4)-epoxymaalian-8alpha-ol. The identities of these metabolites were es...
