Calmodulin-like (CML) genes function in regulating plant responses to different abiotic stresses, such as high salt and drought. Using japonica type rice seedlings (‘Nipponbare’), we induced the expression of OsCML4 (Accession No. NM_001057768), which encodes a rice CML protein. Under drought conditions, transgenic plants over-expressing that gene exhibited(More)
Four crystalline and one liquid compounds were isolated from the solid cultured extract of Hericium erinaceus, Two of them are new, named herein III and IV. Their chemical structures were determined as 6-methyl-2,5-dihydroxymethyl-gamma-pyranone (III) and 2-hydroxymethyl-5-alpha-hydroxy-ethyl-gamma-pyranone (IV). The others are(More)
In an attempt to search for novel antihypertensive or antiarrhythmic agents, especially compounds mainly acting on calcium or potassium channels, with the isoquinoline alkaloids which possessed cardiovascular effects as lead compounds, and on the basis of previous works of our laboratory as well as integration of the structural feature of certain potassium(More)
