The Delta-12 oleate desaturase gene (FAD2-1), which converts oleic acid into linoleic acid, is the key enzyme determining the fatty acid composition of seed oil. In this study, we inhibited the expression of endogenous Delta-12 oleate desaturase GmFad2-1b gene by using antisense RNA in soybean Williams 82. By employing the soybean cotyledonary-node method, a part of the cDNA of soybean GmFad2-1...

This paper presents an analysis of the economics of the 1947 Soviet famine, using data from recently declassified archives. It is argued that the best estimate that can currently be given of the number of excess deaths is the range 1·0–1·5 million. The demographic loss was greater. During the famine, surplus stocks in the hands of the state seem to have been sufficient to have fed all those who...

To produce unsaturated fatty acids, membrane-bound fatty acid desaturases (FADs) can be exploited to introduce double bonds into the acyl chains of fatty acids. In this study, 19 membrane-bound FAD genes were identified in Gossypium raimondii through database searches and were classified into four different subfamilies based on phylogenetic analysis. All 19 membrane-bound FAD proteins shared th...

As reported previously, FMS* has been synthesized as a coenzyme analogue1 ) and has been found to inhibit D-amino acid oxidase in competition with FAD2)3 )4). On the other hand, it has been observed that FMS has an inhibitory action on the growth of riboflavin requiring bacteria5). From these results, it was supposed that FMS, as an antivitamin B2, disturbs the metabolic pattern in higher anima...

BACKGROUND Jatropha curcas is recognized as a new energy crop due to the presence of the high amount of oil in its seeds that can be converted into biodiesel. The quality and performance of the biodiesel depends on the chemical composition of the fatty acids present in the oil. The fatty acids profile of the oil has a direct impact on ignition quality, heat of combustion and oxidative stability...

Soybean oil is a traditional edible oil. Increasing the oleic acid content an important direction of soybean breeding. The FAD2 family consists seven genes that regulate how converted into linoleic acid. Five gene family, GmFAD2-1B, GmFAD2-1A, GmFAD2-2B, GmFAD2-2C, and GmFAD2-2D, were taken as target in this study. Firstly, multivalent CRISPR/Cas9 gene-editing vector was constructed to expressi...

شاخص سطح برگ استخراج‌شده (LAI) از تصاویر سنجش دور پارامتر مهمی، به‌منظور مدل‌سازی مکانی تولید پوشش گیاهی، محسوب می‌شود. معمولاً شاخص‌های گیاهی که با بازتاب طول موج‌های قرمز و مادون نزدیک محاسبه می‌شوند، در برآورد LAI استفاده روش‌های آماری، به‌کار می‌روند اما بسیاری این شاخص‌ها مقادیر متفاوت به اشباع می‌رسند. برای رفع محدودیت، محدودة لبة شده است؛ بنابراین، باید قابلیت داده‌های دور، ذرت علوفه‌ای، ...
