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 traits shows that they interfere with the action or production of the gibberellin (GA) ...

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...
population size. Notably, the Xizang genome has more transposable elements (TEs) and more gene loss-of-function (LoF) mutations. Differentially expressed genes were enriched in biological processes of cellular response to oxygen-containing compound, regulation of defense response, and response to light...
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...
