Rice and Genetic Engineering
Rice is the main food for about one-third to one-half of the world's population. A mature rice plant is usually two to six feet tall. In the beginning, one shoot appears. It is followed by one, two, or more offshoots developing. There are at least five or six hollow joints for each stalk, and a leaf for each joint. The leaf of the rice plant is long, pointed, flat, and stiff. The highest join of the rice plant is called the panicle. The rice grains develop from the panicles. (Jodon, 300) Rice is classified in the grass family Gramineae. Its genus is Oryza and species O. sativa. It is commonly cultivated for food in Asia. Some varieties of rice include red rice, glutinous rice, and wild rice. (Jodon, 303) The kernel within the grain contains most of the vitamins and minerals (298). The kernel contains thiamine, niacin, and riboflavin (299). Rice has many enemies that destroy a majority of the rice crops. The larvae of moth, stem borers, live in the stems of the rice plants. Some insects suck the plant juices or chew the leaves. Birds, such as bobolink, Java sparrow, or paddybird, would eat the seeds or grains. Disease causing factors such as fungi, roundworms, viruses, and bacteria also destroy the ri
are clustered along the middle Yangtze in Hubei and Hunan provinces. A majority of rice grown is cultivated rice. The ship captain presented the governor with a sack of seed rice. This type of rice, called "miracle rice", because of its high yields. Spain was introduced to rice when it was conquered by the Moors during the 700's A. The dried stalks of rice are used to make sandals, hats, raincoats, and thatching roofs. This new breed was thought to have been to reduce the food shortages that depend on rice as a staple food, but because of various conditions in other countries, this rice plant was not very successful. Scented rice is the most expensive because is has long grains and tastes like popcorn when cooked. suggests that rice cultivation originated in the middle Yangtze and spread from there".
