oospore उदाहरण वाक्य

उदाहरण वाक्य

1. Oospores ( thick-walled, resting spores ) of " P . cubensis " are rare and their role in nature is unknown.
2. The co-occurrence of the two mating types is significant due to the possibility of sexual recombination and formation of oospores, which can survive the winter.
3. Microscopic identification of an oospore that measure around 40 micrometers in diameter from a soybean plant sample is a definite sign of " Phytophthora sojae ".
4. Once germinated, oospores can produce either a germ tube, which directly infects the plant, or a sporangium, which releases zoospores that infect the plant.
5. After entering an area, the eradication of the pathogen is difficult due to the formation of oospores, which can remain viable in soil for many years.
6. Once fertilized, the zygote either becomes an encysted or motile oospore, which ultimately becomes a resting spore that will later germinate and give rise to new zoosporangia.
7. Karyogamy between these two types of gametangia one being from the A1 sexualtype and the other of the A2 sexual type results in the formation of an overwintering oospore.
8. This is because the oospores don t germinate together at the same time; rather they each have their own distinct favorable condition in which they ll initiate their germination.
9. In oomycetes, the zygote forms through the fertilization of an egg cell with a sperm nucleus and enters a resting stage as a diploid, thick-walled oospore.
10. The thick-walled oospores are the main overwintering structures, but the mycelium can also survive in conditions where all the plant material is not destroyed during the winter.
