Moreover amplification of the above mentioned region produced double-banded products for hybrid and dikaryotic isolates (Fig.
(2001).The amplification of 5' end of IGS2 region could clearly identify two types of monokaryons (A and B) and was able to separate the dikaryotic cultures from monokaryotic which were wrongly isolated as
-- Isolates and strains of Gloeophyllum used in the decay tests (all are dikaryotic tissue isolates).
Germination with phragmobasidia; basidial cells often conjugate; dikaryotic cells grow with hyphae elaborating elongated dikaryotic blastoconidia.
After deposition in the flower, spores germinate to produce haploid cells of opposite mating type that conjugate to form infectious dikaryotic hyphae.
Our study shows that even when inoculations are performed by direct injection of infective stages of the fungus into the host tissue, bypassing any resistance mechanism operating between spore deposition and host entry of the produced dikaryotic hyphae, direct effects of inoculation resistance explained a significant proportion or the variation in resistance among host families in the field.
