Water bamboo, also known as water bamboo shoots, gazania bamboo shoots, Pa Bai bamboo shoots, Mizuso, Mizuso grass, Mizuso Chiang, Mizuso vegetables, Mizuso bamboo shoots, water bamboo shoots, water bamboo poop, water bamboo squash, high bamboo shoots, wild rice, wild rice, wild rice, wild rice, wild rice, wild rice ear, wild water bamboo, the ancient name of the Mizuso or Mizuso green shoots. It belongs to the genus Zizania of the family Graminae, and is a common vegetable in southern China.

The seeds are black and edible, and are known as wild rice, wild rice, water bamboo rice, water plant rice, and carved rice. "Mushroom rice", called "Jiang" in ancient China, is one of the six grains eaten by the Son of Heaven, which shows that earlier cultivation of Mushroom grass in China was based on the harvesting of seeds and grains.

Later, it was discovered that some Mushroom grass was infected with black powder fungus and did not draw spikes, the stem began to expand, and gradually formed a spindle-shaped fleshy stems, which are now consumed by the wild rice shoots. As a result, farmers began to propagate the diseased, deformed plants as a vegetable, and now those that do produce fruits are regarded as degraded wild species.

The black spikenard fungus, when parasitized by the mongoose, secretes growth hormone, cytokinin, and ethylene, which stimulate the growth of the thin-walled cells of the mongoose's young stems to divide, and at the right temperature, the cells proliferate and expand, forming long spindle galls, and at the same time, transferring nutrients made by photosynthesis of the leaves to the galls. This galls, form young shoot stems, that is, edible wild rice shoots . Once the temperature exceeds 30 ℃ or below 10 ℃ will inhibit the activities of the black fungus, thus affecting the shoots.

The Mizogiku Kuroshiobacteria are preserved and reproduced along with the wild rice shoots. When you cut open a wild rice shoot, you will find a black spot the size of a sesame seed inside, which is the spore mound of Kuroshio bacteria, and countless black-brown thick membrane spores will be formed inside, the spores are spherical to ellipsoidal, yellow-brown, and have a fine prickle, and the diameter is 6-9 micrometers.

Many people see the black spots on wild rice beans and think that they are bad. In fact, these black spots are the focus of the anti-osteoporosis program of wild rice beans, and they are a kind of fungus called Zizania nigra, which has positive effects on metabolism. The black dots are a fungus called Mizuna nigra, which has positive effects on some metabolisms, slowing the aging of bones.

The oracle white often has a black heart when it's hot, but the black dots are residual mongoose fungus, so there's no problem eating it.
