Researchers Alter Ethylene Production in Corn to Combat Drought Stress
Scientists from DuPont Pioneer used gene-silencing approach
to modulate the levels of ethylene biosynthesis in corn and
study its effect on grain yield under drought conditions in
the field. The results of the study were released in Plant
Commercially relevant transgenic events were created with
down-regulated ACC synthases (ACSs), enzymes that catalyse
the rate-limiting step...
Chinese Scientists Crack Genome of Tree Cotton
Scientists from Chinese Academy of Agricultural Sciences and
Beijing Genomics Institute successfully decoded the genome
sequence of tree cotton (Gossypium arboreum). The details of
the sequence are published in Nature Genetics.
After the successfully sequencing wild cotton G. raimondii
in 2012, researchers started the work on deciphering the
genome of G. arboreum. They used whole-genome shotgun
Arabidopsis Overexpressing the CaMBPF1 Gene has Reduced Abiotic Stress Tolerance
Low temperature is the main reason for the economic losses
in pepper (Capsicum annuum) global production. Cold-related
genes regulated by abscisic acid (ABA) have already been
identified in previous studies, including the CaMBF1, a gene
homologous to potato MBF1 (StMBF1) encoding the coactivator
multiprotein bridging factor 1. The study focused on the
characterization of the CaMBF1...
Study Says Some Crops are Less Nutritious as CO2 Levels Rise
A new study conducted by researchers from eight institutions
in Australia, Israel, Japan, and the United States report
that as the atmospheric carbon dioxide (CO2) levels rise
this century, some grains and legumes will become
significantly less nutritious than they are today.
The researchers looked at various varieties of wheat, rice,
field peas, soybeans, maize, and...
Discussion on Benefits of Biotech Crops in Egypt
A workshop was organized by the Egypt Biotechnology
Information Center (EBIC) at the International Agriculture
Center in Egypt. Dr. Clive James, ISAAA Chair Emeritus,
presented the global status of commercialized biotech crops
in 2013. The workshop was held under the auspices of the
Ministries of Agriculture and Environment and was attended
by hundreds of academicians, researchers,...
Transgenic American Chestnuts Exhibit Intermediate Resistance to Chestnut Blight
American chestnut (Castanea dentata) is a native keystone
species that was nearly eradicated by chestnut blight caused
by the fungal pathogen, Cryphonectria parasitica. A new
approach to producing American chestnut trees with enhanced
blight resistance is through Agrobacterium-mediated
transformation. This report describes the progress towards
producing a blight-resistant American chestnut tree.
The transgenic American chestnut ‘Darling4,' which
Metal-Eating Plant Discovered in the Philippines
Scientists from the University of the Philippines Los
Baños (UPLB) have discovered a new plant on the western
part of Luzon Island that eats nickel. The plant, called
Rinorea niccolifera, accumulates up to 18,000 ppm of nickel
in its leaves without being poisoned, an amount which is a
hundred or a thousand times higher than...
UK Consortium to Work on Cropping Systems that Will Harness Soil Phosphorous
A new project by a scientific consortium including the James
Hutton Institute, Rothamsted Research, and Lancanster
University looks into cropping systems that will make soil
organic phosphorous available to plants. According to Dr.
Martin Blackwell, Soil Scientist and Principal Investigator
on the project at Rothamsted Research, "This is an exciting
opportunity to explore how soil organic...
Milk-Bundle Proteins Improve Seed Nutritional Quality of Transgenic Soybean
There has been great progress achieved with genetic
engineering in improving soybean protein quality. However,
these improvements are not sufficient to meet the
nutritional requirements for food and feed. This recent
study aimed to increase soybean sulfur amino acid content by
expressing the de novo Milk Bundle protein MB-16, in
transgenic soybean seed.
The MB-16 gene, originally...
Biotech Crops Continue to Benefit the Environment and Farmers
PG Economics released the latest report on the global
socio-economic and environmental impacts of GM crops from
1996-2012 written by Graham Brookes and Peter Barfoot.
According to Graham Brookes, in the 17th year of widespread
planting of GM crops, more environment friendly farming
practices and increased farmers productivity and income were
evident in 2012. It was...
