(1) The gametophyte is haploid, that is, each cell contains a single complete set of chromosomes, and arises from the germination of a haploid spore .

(2) A spore can infect a plant and cause a new lesion which will produce spores in 7-10 days.

(3) Grain mold fungi also produce spores capable of aerial dispersal in the field as well as within a grain storage bin.

(4) While the spores are not extremely long lived, they could survive this form of movement.

(5) A concentration of just 5 parts per million was adequate to eradicate 50,000 spores under laboratory conditions.

(6) In the production of dry milk these bacterial spores are able to survive the spray-drying process.

(7) The scientists' next step, for most pathogens, is to collect the spores .

(8) It reproduces prolifically and produces spores at all stages of its life.

(9) After landing on a host plant, spores germinate and produce a germ tube that grows across the leaf surface.

(10) When contaminated seeds are planted, bunt spores germinate in the presence of moisture and infect the wheat seedlings.

(11) At flowering, the fungus grows through the floral tissue and forms masses of spores in place of healthy seed.

(12) Bunt fungi survive as resting spores on contaminated seed.

(13) When infected flowers or leaves are plucked, a grayish-white cloud of fungal spores can usually be seen.

(14) Many questions concerning toxicity and allergenicity have been raised about corn contaminated with the spores of this fungus.

(15) It is heat-sensitive and dies as it dries, so is a much less attractive weapon than anthrax spores , which are many thousands of times more resistant.
