Surgery and soil accumulation of eliminated leaves significantly reduced leaf area exposed to ascospore discharge and decreased up to 80% inoculum production potential and black sigatoka severity (OROZCO-SANTOS et al., 2002).
As an example, consider the GO concept ascospore formation.
The levels of oleic and palmitoleic acids gradually increased during both the growth phase and the lipid accumulation phase, which coincides with ascosporogenesis, while the concentrations of linoleic, stearic, and palmitic acids decreased towards the start of ascospore formation by D.
hansenii strains are haploid and can be reproduced vegetatively by forming of multilateral budding [3] via sexual reproduction (heterogamous conjugation) leading to short diplophase and then by meiosis and ascospore formation.
Basically, 17 years of research (1).(2) has shown that significant ascospore release can occur when the temperature is above 45[degrees] F and the bark is wet.
In the context of the species specific database these unique terms are either highly relevant to the species and only ever likely to have been used in annotation by the curators of the species specific database (e.g., "ascospore formation" within PomBase and SGD, "fin development" within ZFIN) or represent terms that only cooccur with the query term in this database compared to UniProtKB.
Only the ascospore ornamentation differs, and the subtle differences cannot be seen by using light microscopy.
To provide favorable conditions for ascospore liberation and infection, irrigation was for 30 s every 30 min in the morning (0600 to 0800 h) and in the afternoon (1600 to 1800 h).
Perithecia were ovoid to spherical, reddish to reddish-brown, 380-700 x 350-650[micro]m, smooth and shining, with a slightly protruding, domed and darkened apical ostiole through which ascospore were extruded in white of buff tendrils, The perithecial wall did not show a pseudoparenchymatous structure but was composed of ah intertwining network of thickened hyphae.
Observations made in experimental field plots and ascospore progeny analysis indicated prevalence of specific matings between stromata of the same host suggesting that flies are species specific in their visitation behavior.
However, the mode of transmission could be uncoupled from that of reproduction, for example by loss of ascospore formation but maintenance of horizontal transmission by conidia.
