explain the process of hapolidization employed by the conidial fungi to provide genetic recombination
Added by Nicole R.
Step 1
These conidia are formed through a process called conidiation, where specialized structures (conidiophores) develop and release conidia into the environment. Show more…

Understanding the types of reproductive compatibilities examined by the researchers requires knowledge of the life cycle of these fungi. The anthers of infected plants produce diploid teliospores instead of pollen. After pollinators transport them to a new host, these teliospores go through meiosis. Haploid sporidia are the products of meiosis, and these have two mating types (a1 and a2), and hence are like gametes. Conjugation, which is equivalent to fertilization, occurs between sporidia of opposite mating types. After conjugation, the diploid zygote forms hyphae on the new host plant. If successful, the hyphal formation leads to systemic infection. Eventually, new diploid teliospores are produced, and the cycle begins anew.

Fungi have a haploid dominant life cycle in which growth is accomplished through meiosis. When [ Select ] of two different mating types fuse during [ Select ] the resulting cell is [ Select ]. [ Select ] results in a diploid cell that undergoes [ Select ] and results in [ Select ] that are [ Select ]

In fungi, haploid hyphae fuse to produce dikaryotic and then diploid nuclei, only to restore the haploid condition by meiosis before the growth of new hyphae. What is the significance of a transient diploid state in fungi? the fusion of two nuclei increases the genetic pool of the fungi it allows the fungus to produce diploid spores occasionally these processes are the only way in which fungi can maintain genetic variability
