During the "Green Revolution" of rice, high-yielding varieties (HYVs) were developed using a semi-dwarf gene (sd1 or OsGA20ox2). The presence or absence of the two mutant alleles (DGWG type in Dee-geo-woo-gen and JKK type in Jikkoku) were surveyed by PCR using 256 accessions of eight wild and two cultivate rice species. The DGWG allele was detected in a landrace (Oryza sativa) and two accession...

Forensic botany encompasses many sub-disciplines, including plant anatomy, plant ecology, plant systematics, plant molecular biology, palynology, and limnology. Although the field of forensic botany has been recognized since the mid-1900's, the use of trace plant material as physical evidence in criminal casework is still novel. A review of published forensic casework that used plant evidence i...

BACKGROUND AND AIMS Most plant scientists, in contrast to animal scientists, study only half the organism, namely above-ground stems, leaves, flowers and fruits, and neglect below-ground roots. Yet all acknowledge roots are important for anchorage, water and nutrient uptake, and presumably components of yield. This paper investigates the relationship between domestication, and the root systems ...

Biodegradable plastics are those that can be completely degraded in landfills, composters or sewage treatment plants by the action of naturally occurring micro-organisms. Truly biodegradable plastics leave no toxic, visible or distinguishable residues following degradation. Their biodegradability contrasts sharply with most petroleum-based plastics, which are essentially indestructible in a bio...

China's urbanization will influence the future world economic development. China's s urbanization rate is from 10.6% in1949 to 53.73% in 2013, and the research center of the experts predict that China's urbanization rate will reach 60% in 2020.The characteristic of China's urbanization is the coordinated development of four modernizations, which includes informatization, industrialization, urba...

Brown explained that, because animals are inefficient in converting vegetable protein into animal protein, "the production of meat, milk, and eggs requires the use of large amounts of grain as animal feed." As a result, "it requires a ton of grain per year for the diet of the average American. Only 150 pounds of this are consumed directly. In contrast, the average person in the poor nations of ...

India’s Green Revolution made the country a world leader in rice and wheat production, but it has taken its toll on people environment. In an era of climate change population growth, agriculture must be sustainable. Pathways to this ambitious goal require new approaches agricultural policy research. green revolution at expense Here, we call for transformative changes reduce greenhouse gas emiss...

Another "green revolution" is needed for crop yields to meet demands for food. The international C(4) Rice Consortium is working toward introducing a higher-capacity photosynthetic mechanism--the C(4) pathway--into rice to increase yield. The goal is to identify the genes necessary to install C(4) photosynthesis in rice through different approaches, including genomic and transcriptional sequenc...
