Genetically modified plants hold the key to saving the banana industry
Scientists have genetically modified a trial crop of banana plants to survive Tropical Race Four, a fungus that has wiped out plantations in the Northern Territory. The modified plants have been inserted with a gene that starves the fungus, preventing it from attacking the plant.
Identity theft by aphids
Researchers discovered aphids on ginger and heliconia plants have genetic differences from those on banana plants, reclassifying them as a separate species Pentalonia caladii. This finding has significant implications for the biological control of banana aphids and preventing the spread of BBTV.
Apathetic aphids with attitude become easier prey for ladybugs
Researchers found that apathetic aphids, accustomed to ignoring pheromone alarms, are more vulnerable to ladybug attacks. This study provides a potential strategy for increasing the effectiveness of aphid predators in crop protection.
Scientists find new evidence of genetically modified plants in the wild
Researchers found established populations of genetically modified canola plants outside agricultural fields in North Dakota, reproducing and adapting to local environments. This discovery highlights concerns about the spread of biotech products and their impact on native species.
A new approach that saves eyesight and lives in the developing world
A new approach to boosting vitamin A levels in corn has been developed by US scientists, with potential to reduce child blindness and mortality in developing regions. The research identified genetic sequences linked to higher beta-carotene levels in corn and demonstrated an inexpensive method to identify and breed high-yielding varieties.
New genetic model predicts plant flowering in different environments
A Brown University-led research team has created a genetic model that charts the internal and external signals guiding plant flowering across its native climate range. The model accurately predicts how plants will respond to environmental cues and can be used to understand how plants will adapt to future climate conditions.
A big bunch of tomatoes?
A new study identifies a genetic pathway that determines the pattern of flower growth in tomato plants. The researchers found that manipulation of this pathway can turn a single stem into hundreds of branch-bearing shoots, increasing crop yields.
MSU scientists find new gene that helps plants beat the heat
Researchers found a novel gene, bZIP28, regulating heat stress response in Arabidopsis thaliana. This discovery may lead to creating crops more resilient to warmer climates.
Managing uncertainty important in ecological balance: ASU researcher
Ecological balance diverges across cultural, economic and political perspectives, according to ASU researcher Ann Kinzig. The biosphere can be both robust and fragile, with instability in one part required for stability in another.
Genetically modified carrots provide more calcium
Researchers at Baylor College of Medicine developed genetically modified carrots that increase the transport of calcium across plant cell membranes. The modified carrots can provide up to 41% more bioavailable calcium than regular carrots, making them a promising source for improving bone mineral density and treating osteoporosis.
Battling virus disease of watermelon with bottlegourds
Researchers have discovered 36 bottlegourd accessions with complete resistance to ZYMV, a major scourge of commercial cucurbits. Grafting popular watermelon cultivars onto resistant bottlegourd rootstocks may provide a sustainable solution to control the virus.
UCSD biologists solve plant growth hormone enigma
Researchers at UCSD have identified a family of 11 genes involved in the synthesis of auxin, a key plant hormone. Disrupting these genes reveals that localized production of auxin controls plant architecture, contradicting previous assumptions. This discovery has significant implications for crop improvement and development.
UC San Diego biologists solve plant growth hormone enigma
Researchers identified a family of 11 genes involved in auxin synthesis and found that their localized production influences plant development. This discovery can be applied to agricultural problems like producing seedless fruit or stronger stems.
Vaccine put into tomatoes shows promise fighting virus in lab tests
Researchers at the University of Illinois have developed a vaccine approach to fight the respiratory syncytial virus (RSV) by infusing it into genetically modified cherry tomatoes. The study found that mice fed with these vaccine-containing tomatoes showed increased antibody production, providing protection against the virus.
DNA fingerprinting reveals surprise in wine-grape family tree
Researchers used DNA fingerprinting to identify 16 wine-grape varieties, including Chardonnay, as the offspring of Pinot and Gouais blanc. This discovery provides valuable information for grape breeders, allowing them to preserve old varieties and develop new ones.
Beyond Jurassic Park: Real Science With Ancient DNA
Researchers successfully revived bacteria extracted from ancient bees preserved in amber, opening up new possibilities for pharmaceuticals and industrial applications. Ancient plant specimens are also being studied to understand genetic evolution and identify potential biocontrol uses.
