7、nts always know which way to growinto the soil but not above it? Some British scientists have recently solved this mystery. It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the F
8、ebruary 29 issue of Journal Science. The key is in the fuzzy(有绒毛的) coat of hairs on the roots of plants, says professor Liam Dolan. We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear. Root hairs explore the soil in much the
9、same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. I the meantime, the plant is held in place as the hairs grip the soil. The hairs are guided by a clever chemical trick. A protein(蛋白质) at the
10、 tip of the root hairs called RHD2 helps them to take calcium(钙) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium. But when an obstacle blocks the hairs path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direct
11、ion. This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan. In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this ad
12、aptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments. According to Dolan, Research in the John Inners Center is taking a breeding approach(育种方法) to increase hair length in wheat but it will be some time before new cultivars(栽培变种) are developed.(1)The

24、ce the amount of single-use plastic usage in order to protect and save marine (海洋的)wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the great loss of marine life, but theyre a great place to start because theyre something that are used
25、by millions of Americans who are unaware that theyre so damaging. Americans use more than 500 million straws daily, which is enough to fill 127 school buses each day and they cant be recycled.
