Characterization and molecular cloning of conjugation-regulating sex pheromones in homothallic Closterium.
Conjugation-regulating pheromones were analyzed in homothallic Closterium for the first time. Members of the Closterium peracerosum-strigosum-littorale complex are unicellular charophycean algae in which there are two modes of zygospore formation: heterothallism and homothallism. A homothallic strain of Closterium (designation, kodama20) forms selfing zygospores via the conjugation of two siste...
متن کاملMaintaining heterokaryosis in pseudo-homothallic fungi
Among all the strategies displayed by fungi to reproduce and propagate, some species have adopted a peculiar behavior called pseudo-homothallism. Pseudo-homothallic fungi are true heterothallics, i.e., they need 2 genetically-compatible partners to mate, but they produce self-fertile mycelium in which the 2 different nuclei carrying the compatible mating types are present. This lifestyle not on...
متن کاملGene expression during oosporogenesis in heterothallic and homothallic Phytophthora.
A large-scale screen for genes induced during sexual development was performed in the heterothallic oomycete Phytophthora infestans, the potato blight agent. Of 15,644 unigenes on an Affymetrix chip, 87 were induced >10-fold during mating, with 28 induced >100-fold. This was validated in independent matings using RNA blots and RT-PCR. Only 44 genes resembled sequences in GenBank. These encoded ...
متن کاملSpecies and Varieties in the Rhizopus Arrhizus-rhizopus Oryzae Group as Indicated by Their Dna Complementarity
DNA renaturation experiments gave evidence to conclude that Rhizopus arrhizus, R. OIyzae, R. delemar, Amylomyces rou.xii, R. delemar var. minimus, R. delemar var. multiplicisporus, R. arrhizus var. delemar, R. chungkuoensis var. isqfermentarius, and R. javanicus var. kawasakiensis can be accommodated in three taxa, namely, R. arrhizus var. arrhizus, R. arrhizus var. rozedi, and R. arrhizus var....
متن کاملRhizopus Soft Rot on Pear (Pyrus serotina) Caused by Rhizopus stolonifer in Korea
Rhizopus soft rot caused by Rhizopus stolonifer occurred on pears (Pyrus serotina) in the Jinju City Agricultural Products Wholesale Market in Korea from 2004 to 2005. The infection usually started from wounds due to cracking at harvest time. The lesions started as water-soaked, rapidly softened, then gradually expanded. The mycelia grew vigorously on the surface of the fruits and formed stolon...
