Bakanae disease is caused by a fungus Gibberella fujikuroi. It is also called as foolish seedling disease. It affects the rice plants through the root. The affected seedling show abnormal elongation.

Dikaryotisation $(n+n)$ in Agaricus is brought about by
1 Clamp connections
2 Somatogamay between two hyphae of different strains
3 Both (a) and (b) are correct
4 Basidiospores
Explanation:
Dikaryotisation $(\mathrm{n}+\mathrm{n})$ in Agaricus is brought about by clamp connections and somatogamay between two hyphae of different strains. The vegetative part of the mycelium consist of two filamentous hyphae that produces the basidiospores. - In the beginning, the hyphae are nucleated but later two strains of hyphae are formed and both of them come in contact, as a result the nucleus passes from one to the other this process is termed as somatogamy. The cells become dikaryotic after the division by clamp and considered as dikaryotic mycelium.

Which of the following is correctly matched for the product produced by them?
1 Acetobacter aceti : Antibiotics
2 Methanobacterium : Lactic acid
3 Penicillium notatum : Acetic acid
4 Saccharomyces cerevisiae : Ethanol
Explanation:
Saccharomyces cerevisiae is also called Baker's yeast and it used in the fermentation of sugars to produce ethanol and carbon dioxide. - Acetobacter aceti produce acetic acid. - Methanobacterium produce methane. - Penicillium notatum and streptococcus produce antibiotics penicillin and streptomycin respectively.

Among plants, Pheromones are secreted by the cells of the following plants for given function:
1 all plants for growth and development
2 yeast for facilitating mating
3 all fungi for sexual reproduction
4 Rhizopus for formation of zygospore
Explanation:
Pheromones are also called ectohormones substance that are secreted outside by an individual and received by a second individual of the same species in which it induces a specific reaction. - Pheromones may play a role in mate selection, which is "disassortative" regarding the human leukocyte antigen- (HLA) genotype.
