The spectacular increases in wheat and rice yields during the 'Green Revolution', were enabled by the introduction of dwarfing traits into the plants. Now, identification of the genes responsible for these trait
When the green revolution began in the 1960s, it was before the revolution in molecular genetics: IR8, the first miracle rice, was bred without knowledge of the genes that blessed it with high yields. Breeders today can zero in on genes, but they still use traditional techniques and ever ...

They also developed plants that produced higher quantities of grain.Borlaug worked with wheat genes to shrink (缩小) the plant while keeping the grain large.Using the same amount of land, the new strain of wheat could produce three to four times as much food. This method would become the ...
C The worldwide 20{n} century “Green Revolution", which saw huge year-by-year increases in global grain vields (产量), was fueled by the development in the 1960s of new high-yielding dwarfed (矮小的) varieties known as Green Revolution Varieties (GRVs).These dwarfed GRVs are common al...
We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1 (SD1), both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s. Understanding how phytohormone pathway genes regulate plant architecture and ...
A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering (9) usually involves taking genes from one species and inserting them into another (10) to transfer a desired characteristic. This could mean, for example, selecting a gene...
A. It promotes other genes' activity. B. It increases the output of crops. C. It takes in nitrogen from the soil. D. It lowers fertilizer input levels. 相关知识点: 试题来源: 解析 答案见解析 (1)推理判断题。根据第一段The worldwide 20th century "Green Revolution",which saw huge year...
While genetics are never the whole story, choices about tree genes and early nurture clearly have a major role to play. There are two key practices: Advanced genetic improvement entails gene mapping and marker-based breed selection to ensure plants have the genetic profile best suited to the ...
The Green Revolution is often seen as epitomising the dawn of scientific and technological advancement and modernity in the agricultural sector across developing countries, a process that unfolded from the 1940s through to the 1980s. Despite the time that has elapsed, this episode of the past con...
