This study was caried out to identify varietal diferences in poping characteristics of brown and polished rice and toelucidate the morphological and physicochemical properties related to poping quality. Nineteen rice varieties including japonica,argevarie

A new white colored spray rose (Rosa hybrida Hort.) cultivar Danmi was developed at the Jeollanamdo AgriculturalResearch and Extention Services (JARES) after seedling and line selection in 2002, and its characteristics were examined twicefrom 2004 to 2005

A new rice variety Manweolbyeo is a japonica type developed by the rice breeding team of Yeongnam Agriculturalivationcondition from the progenies of a single cross of Milyang120/Hwayeongbyeo. The selected line(YR16326-8-3-2) from the prog-enies of it cros

Ascorbate peroxidase (APX) plays a crucial role in the detoxification of hydrogen peroxide. APX activity is maintained significantly higher in the paraquat­treated leaves of the paraquat-tolerant Rehmannia glutinos. This study was conducted to understand structural and regulatory characteristics of APX gene in R. glutinosa. A putative APX cDNA clone (RgAPX1) was isolated from a leaf cDNA library using a partially sequenced expressed sequence tag clone. RgAPX1 is consisted of 1148 bp nucleotides and contains an open reading frame encoding a 250 amino acid-long polypeptide. Deduced RgAPX1 amino acid sequence shares higher sequence similarity to cytosolic APXs. RgAPX1. expression was higher in the leaf than in the flower and root. Southern blot result indicates the presence of one or two RgAPX1-related genes in R. glutinosa genome. RgAPX1 transcription was affected differentially by various stresses and phytohormone. The results indicate that RgAPXl is constitutively expressed in most tissues and its expression is modulated for the immediate and efficient detoxification of H2O2 under normal and stress conditions.
