Novel allelic variant of Lpa1 gene associated with a significant reduction in seed phytic acid content in rice (Oryza sativa L.).

In plants, myo-inositol-1,2,3,4,5,6-hexakisphosphate (InsP6), also known as phytic acid (PA), is a major component of organic phosphorus (P), and accounts for up to 85% of the total P in seeds. In rice (Oryza sativa L.), PA mainly accumulates in rice bran, and chelates mineral cations, resulting in mineral deficiencies among brown rice consumers.

Burden of Respiratory Disease in Korea: An Observational Study on Allergic Rhinitis, Asthma, COPD, and Rhinosinusitis.

Purpose: The Asia-Pacific Burden of Respiratory Diseases (APBORD) study is a cross-sectional, observational one which has used a standard protocol to examine the disease and economic burden of allergic rhinitis (AR), asthma, chronic obstructive pulmonary disorder (COPD), and rhinosinusitis across the Asia-Pacific region. Here, we report on symptoms, healthcare resource use, work impairment, and associated costs in Korea.

Methods: Consecutive participants aged ≥18 years with a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled.

Tomato () variety discrimination and hybridization analysis based on the 5S rRNA region.

The tomato () is a major vegetable crop worldwide. To satisfy popular demand, more than 500 tomato varieties have been bred. However, a clear variety identification has not been found.

Sensitivity of translation initiation factor eIF1 as a molecular target of salt toxicity to sodic-alkaline stress in the halophytic grass Leymus chinensis.

Eukaryotic translation initiation factors (eIFs) have been shown to be critical in the initiation of protein synthesis. Here, we report the cloning and characterization of a novel gene, LceIF1, from a potentially interesting forage grass, Leymus chinensis (Trin.).

Effect of chitinase on resistance to fungal pathogens in sea buckthorn, Hippophae rhamnoides, and cloning of Class I and III chitinase genes.

Sea buckthorn (Hippophae rhamnoides L.) is naturally distributed from Asia to Europe. It has been widely planted as an ornamental shrub and is rich in nutritional and medicinal compounds.

A case of unilateral ashy dermatosis.

Ashy dermatosis, also known as erythema dyschromicum perstans, is a peculiar, slowly progressive, idiopathic dermal melanosis. In most cases, slate gray- to lead-colored patches are symmetrically distributed over the body. Ashy dermatosis with a unilateral distribution is rare.

Expression analysis and functional characterization of the monosaccharide transporters, OsTMTs, involving vacuolar sugar transport in rice (Oryza sativa).

In Arabidopsis, the compartmentation of sugars into vacuoles is known to be facilitated by sugar transporters. However, vacuolar sugar transporters have not been studied in detail in other plant species. To characterize the rice (Oryza sativa) tonoplast monosaccharide transporters, OsTMT1 and OsTMT2, we analysed their subcellular localization using green fluorescent protein (GFP) and expression patterns using reverse-transcription polymerase chain reaction (RT-PCR), performed histochemical beta-glucuronidase (GUS) assay and in situ hybridization analysis, and assessed sugar transport ability using isolated vacuoles.

Ectopic expression of a cold-responsive OsAsr1 cDNA gives enhanced cold tolerance in transgenic rice plants.

The OsAsrt cDNA clone was isolated from a cDNA library prepared from developing seed coats of rice (Oryza sativa L.). Low-temperature stress increased mRNA levels of OsAsr1 in both vegetative and reproductive organs.

PLASTOCHRON3/GOLIATH encodes a glutamate carboxypeptidase required for proper development in rice.

Most aerial parts of the plant body are products of the continuous activity of the shoot apical meristem (SAM). Leaves are the major component of the aerial plant body, and their temporal and spatial distribution mainly determines shoot architecture. Here we report the identification of the rice gene PLASTOCHRON3 (PLA3)/GOLIATH (GO) that regulates various developmental processes including the rate of leaf initiation (the plastochron).

An atypical soybean leucine-rich repeat receptor-like kinase, GmLRK1, may be involved in the regulation of cell elongation.

A leucine-rich repeat receptor-like kinase (LRR-RLK) encoded by one of the genes highly expressed in a specific stage of soybean seed development, referred to as GmLRK1, was identified and characterized. Examination of its kinase domain indicated that GmLRK1 may be a catalytically inactive atypical receptor kinase. An autophosphorylation assay confirmed that GmLRK1 is incapable of autophosphorylation in vitro.

Genetic mapping of the Isaac-CACTA transposon in maize.

We constructed a genetic linkage map with Isaac-TD, SSR, and SNAP markers in a RIL population which had been derived from a cross of waxy corn (KW7) and dent corn (Mo17). A total of 368 markers, including 241 Isaac-TD, 121 SSR, and 6 SNAP markers, were assigned to 10 linkage groups, encompassing 1687.0 cM, with an average genetic distance of 4.

Induction of a homeodomain-leucine zipper gene by auxin is inhibited by cytokinin in Arabidopsis roots.

Homeobox genes are essential regulators of the development of plants as well as other organisms. We chose eight putative Arabidopsis homeobox genes not previously characterized and examined their expression in response to treatment with auxin/cytokinin. One of them, ATHB53, was further studied because it was auxin-inducible and its induction was inhibited by cytokinin.

Position dependent expression of GL2-type homeobox gene, Roc1: significance for protoderm differentiation and radial pattern formation in early rice embryogenesis.

In early plant embryogenesis, the determination of cell fate in the protodermal cell layer is considered to be the earliest event in radial pattern formation. To elucidate the mechanisms of epidermal cell fate determination and radial pattern formation in early rice embryogenesis, we have isolated a GL2-type homeobox gene Roc1 (Rice outermost cell-specific gene1), which is specifically expressed in the protoderm (epidermis). In early rice embryogenesis, cell division occurs randomly and the morphologically distinct layer structure of the protoderm cannot be observed until the embryo reaches more than 100 microm in length.
