Production and Germination of Conidia of Trichoderma stromaticum, a Mycoparasite of Crinipellis perniciosa on Cacao.
ABSTRACT Growth characteristics of the fungus Trichoderma stromaticum, a mycoparasite on the mycelium and fruiting bodies of Crinipellis perniciosa, the causal agent of witches'-broom disease of cacao, were evaluated under controlled environmental conditions. The ability of T. stromaticum to produce conidia and germinate on dry brooms was evaluated at three constant temperatures (20, 25, and 30...
متن کاملNecrotrophic phase of Moniliophthora perniciosa causes salicylic acid accumulation in infected stems of cacao
Moniliophthora perniciosa infects young meristematic tissue of Theobroma cacao and induces abnormal shoot development and ultimately necrosis. We analyzed culture filtrates of M. perniciosa to identify metabolites with possible effects on witches’ broom disease symptom development. All isolates produced salicylic acid (SA), phenyllactic acid and mandelic acid. When SA levels were measured in pl...
متن کاملThe hemibiotrophic cacao pathogen Moniliophthora perniciosa depends on a mitochondrial alternative oxidase for biotrophic development
The tropical pathogen Moniliophthora perniciosa causes witches' broom disease in cacao. As a hemibiotrophic fungus, it initially colonizes the living host tissues (biotrophic phase), and later grows over the dead plant (necrotrophic phase). Little is known about the mechanisms that promote these distinct fungal phases or mediate the transition between them. An alternative oxidase gene (Mp-aox) ...
متن کاملDetermination of QTLs Associated with Agronomic and Physiological Traits under Normal and Salinity Conditions in Barley
mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...
متن کاملExpression analysis of transcription factors from the interaction between cacao and Moniliophthora perniciosa (Tricholomataceae).
Cacao (Theobroma cacao) is one of the most important tropical crops; however, production is threatened by numerous pathogens, including the hemibiotrophic fungus Moniliophthora perniciosa, which causes witches' broom disease. To understand the mechanisms that lead to the development of this disease in cacao, we focused our attention on cacao transcription factors (TFs), which act as master regu...
