The majority of the grains, about 80%, were from cereal crops like barley, and about 10% were bits of roots, including lily, which would have made the beer sweeter, the scientists say.

This case gives the court an opportunity to rein in the growing use of patents to protect genetically engineered crops and other life forms―but the court may well use it to give this trend a powerful new endorsement.

Major supermarkets, in meeting consumer expectations, will often reject entire crops of perfectly edible fruit and vegetables at the farm because they do not meet exacting marketing standards for their physical characteristics, such as size and appearance

This varies dramatically depending on crop, from three calories for plant crops to 35 calories in the production of beef.

Perfectly eatable fruit and vegetable crops often fail to reach supermarkets due to their size or physical appearance

They have caused lots of damage to crops.

Biologist Jill Farrant of the University of Cape Town in South Africa says that nature has plenty of answers for people who want to grow crops in places with unpredictable rainfall.

given the moth's ability also to attack crops like pepper and potatoes, Audu Ogbeh, Nigeria's minister of agriculture, has warned that the pest may "create serious problems for food security" in the country.

I'm targeting crops that are of African value.

In most cases, the human waste is used on grain crops, which are eventually cooked, minimizing the risk of transmitting water-borne diseases.

Now they are trying to figure out what molecular signaling processes activate those seed-building genes in resurrection plants—and how to reproduce them in crops.

Once Farrant and her colleagues feel they have a better sense of which switches to throw, they will have to find the best way to do so in useful crops.

She is hard at work finding a way to take traits from rare wild plants that adapt to extreme dry weather and use them in food crops.

She says she is aware that plenty of people do not want to eat genetically modified crops, but she is pushing ahead with every available tool until one works.

The insect, also known as the tomato leaf miner, devastates crops by feeding on fruits and digging into and moving through stalks.
