[Ghd7, a pleiotropic gene controlling flag leaf area in rice].

Photosynthesis is the unique source of energy for plant. Flag leaf contributed the majority of photosynthate after rice flowering. Ghd7 is a pleiotropic gene, which can significantly increase rice production.

Quantitative trait loci for rice yield-related traits using recombinant inbred lines derived from two diverse cultivars.

The thousand-grain weight and spikelets per panicle directly contribute to rice yield. Heading date and plant height also greatly influence the yield. Dissection of genetic bases of yield-related traits would provide tools for yield improvement.

Development of a double antibody sandwich ELISA assay for the diagnosis of angiostrongyliasis.

With the use of 2 monoclonal antibodies (MAbs) against excretory/secretory (ES) antigens of adult Angiostrongylus cantonensis, a new method was developed for double antibody sandwich ELISA for the detection of circulating antigens (CAg). To evaluate the sensitivity of the new procedure, the CAg in sera of rats (80) and mice (15) infected with A. cantonensis, as well as CAg in sera of clinically confirmed angiostrongyliasis patients (70), were evaluated.

A major QTL, Ghd8, plays pleiotropic roles in regulating grain productivity, plant height, and heading date in rice.

Rice yield and heading date are two distinct traits controlled by quantitative trait loci (QTLs). The dissection of molecular mechanisms underlying rice yield traits is important for developing high-yielding rice varieties. Here, we report the cloning and characterization of Ghd8, a major QTL with pleiotropic effects on grain yield, heading date, and plant height.
