Abstract:
본 발명은 백색미와 프로안토시아니딘계 색소를 종피에 함유하는 유색미의 현미 종피색을 판별하기 위한 프라이머 세트, 상기 프라이머 세트를 포함하는 백색미와 프로안토시아니딘계 색소를 종피에 함유하는 유색미의 현미 종피색을 판별하기 위한 키트 및 상기 프라이머 세트를 이용하여 증폭 반응을 수행함으로써 백색미와 프로안토시아니딘계 색소를 종피에 함유하는 유색미의 현미 종피색을 판별하는 방법을 제공한다. 본 발명의 프라이머 세트를 사용하면 영양생장 후 출수 및 등숙이 이루어진 이후에 종피의 색을 확인할 수 있는 기존의 선발방법에 비해 유색미 판별을 유묘상태에서 가능하게 해주며, 또한 형질의 동형/이형 판별을 가능케 하여 유색미의 조기선발 및 최소자원을 활용한 육종효율을 증진시키는 장점이 있다
Abstract:
PURPOSE: A rice plant with transformed giant embryonic rice is provided to ensure a heavier product than conventional embryos and to obtain rice containing zinc and iron. CONSTITUTION: A cytochrome P450 of giant embryonic rice comprises a base sequence which encodes an amino acid sequence of cytochrome P450 and encodes leucine to a 395th amino acid after translation. A cytochrome P450 gene of rice is a cDNA encoding cytochrome P450. A rice plant is produced by transforming rice plant with a recombinant vector having cytochrome P450 gene. The giant embryonic rice is YR23517Acp79.

PURPOSE: A method for preparing extract derived from young barley leaf is provided to isolate novel ingredients and to be used as a functional material supply source. CONSTITUTION: A young barley leaf extract with an antioxidative activity is prepared using an organic solvent. The young barley leaf is collected in a length of 10-20 cm and is freeze-dried. The organic solvent is methanol or ethanol. The ethanol is 80-90 weight% ethanol solution. A composition for skin whitening or anti-aging contains the extract as an active ingredient. A health food for skin whitening or anti-aging contains the extract as an active ingredient. A solvent fraction of the extract contains one or more compounds selected from compound of chemical formulas 1-4.
Abstract:
A method for evaluating sheath blight resistance is provided to obtain an objective evaluation result conveniently regarding the sheath blight resistance, raise the inoculation efficiency of pathogenic bacteria of the sheath blight and improve the resistance evaluation method, thereby contributing to breed a species with resistance to the sheath blight. A method for evaluating sheath blight resistance comprises the steps of: (a) after inoculating a liquid culture mycelia of Rhizoctonia solani into rice, sealing the inoculation portion tightly using a shielding film such as aluminum foil for maintaining moisture required for vitality of the mycelia; and (b) after cultivating the mycelia inoculated rice until disease is progressed into branches and leaves, evaluating the resistance degree, wherein the resistance degree evaluation is performed by evaluating the attack degree of all leaves sheaths corresponding to the inoculated stem with 0 to 9 steps and calculating a virus infection rate of the inoculated stem in accordance with a following calculating formula of the virus infection rate being equal to (9n9+7n7+5n5+3n3+1n1+0n0)/9N Î 100(wherein each of the n0 to n9 is a number of leaves sheaths corresponding to each of the attack degree evaluated at the mycelia inoculated stem, and the N is the total leaves sheaths of the mycelia inoculated stem).
Abstract:
PURPOSE: A cosmetic composition containing an Echinochloa utilis extract, and a compound isolated from the same are provided to suppress tyrosinase activity and melanogenesis by reducing expression of TRP-1 and TRP-2. CONSTITUTION: A cosmetic composition for skin whitening contains an Echinochloa utilis extract as an active ingredient, and suppresses tyrosinase activity.
