Alternaria blight caused by fungal pathogen devastates Brassica crops such as cabbage, cauliflower, broccoli, and mustard seed. Highly infectious, this fungus can infect the host plant at all stages of growth. Currently Alternaria blight is managed by chemical fungicides, but recently efforts have been made to utilize breeding and modern biotechnological approaches to develop blight-resistant crop varieties.
Plant breeders are always striving to develop new varieties that satisfy growers, producers and consumers. To do this, breeders use genetic markers to bring desirable traits from wild species into their cultivated cousins. Transferring those markers across species has been difficult at best, but a team of grapevine breeders, geneticists and bioinformatic specialists has come up with a powerful new method.
Researchers have discovered a new gene that improves the yield and fertilizer use efficiency of rice.
Mycorrhizal fungi occur naturally in soil and are commercially available as soil inoculants, but new research suggests not all soybean genotypes respond the same way to their mycorrhizal relationships.
A new study that examines the genetics behind the bitter taste of some sorghum plants and one of Africa’s most reviled bird species illustrates how human genetics, crops and the environment influence one another in the process of plant domestication.
A specialized silk covering could protect seeds from salinity while also providing fertilizer-generating microbes.
Citrus greening, a devastating disease, has reduced Florida citrus production by 70%, according to most accounts. Efforts to develop disease control methods have been stymied because scientists have been unable to culture the causal bacterial pathogen.
Quinoa is a healthy food many know and love. As its popularity grows, more farmers are interested in planting it. However, the plant doesn’t do well in high temperatures, so plant breeders are trying to help.
When many people think of watermelon, they likely think of Citrullus lanatus, the cultivated watermelon with sweet, juicy red fruit enjoyed around the world as a dessert. Indeed, watermelon is one of the world’s most popular fruits, second only to tomato – which many consider a vegetable. But there are six other wild species of watermelon, all of which have pale, hard and bitter fruits.
Research combining future climate conditions and arsenic-induced soil stresses predicts rice yields could decline about 40 percent by 2100, a loss that would impact about 2 billion people dependent on the global crop.
