Two genes, accB and accE, that form part of the same operon, were cloned from Streptomyces coelicolor A3(2). AccB is homologous to the carboxyl transferase domain of several propionyl coezyme A (CoA) carboxylases and acyl-CoA carboxylases (ACCases) of actinomycete origin, while AccE shows no significant homology to any known protein. Expression of accB and accE in Escherichia coli and subsequen...

All plant cells produce fatty acids from acetyl-CoA by a common pathway localized in plastids. Although the biochemistry of this pathway is now well understood, much less is known about how plants control the very different amounts and types of lipids produced in different tissues. Thus, a central challenge for plant lipid research is to provide a molecular understanding of how plants regulate ...

Sorghum halepense (L.) Pers. is a troublesome weed of maize which reproduces through seeds and rhizomes. Resistance to ACCase-inhibiting herbicides due target-site mutation Ile-Asn in position 2041 the ACCase gene was confirmed several populations Italy. The presence fitness costs related allelic variant Ile2041Asn has never been investigated ACCase-resistant S. . Three growth analyses pot expe...

Chinese sprangletop (Leptochloa chinensis (L.) Nees) is recognized as the most disturbing weed in rice fields Africa, Australia, and Asia due to causing a significant reduction yields. The habit of lowland farmers Indonesia using high doses herbicides more than once without any rotation, leading increased resistance potential. Therefore, this study aimed confirm level L. acetyl-CoA carboxylase ...

Plant seed oil represents a major renewable source of reduced carbon, but little is known about the biochemical regulation of its synthesis. The goal of this research was to identify potential feedback regulation of fatty acid biosynthesis in Brassica napus embryo-derived cell cultures and to characterize both the feedback signals and enzymatic targets of the inhibition. Fatty acids delivered v...

Hedgehog dogtail (Cynosurus echinatus) is an annual grass, native to Europe, but also widely distributed in North and South America, South Africa, and Australia. Two hedgehog dogtail biotypes, one diclofop-methyl (DM)-resistant and one DM-susceptible were studied in detail for experimental dose-response resistance mechanisms. Herbicide rates that inhibited shoot growth by 50% (GR50) were determ...

This research was conducted to determine the efficacy of quizalofop (FirstAct) herbicide in herbicide-tolerant grain sorghum. FirstAct evaluated for and crop response Double Team (ACCase-tolerant) All herbicides controlled Palmer amaranth 90% or more volunteer corn 95% late season. Johnsongrass control 86 91%. Minor sorghum injury early season did not persist. Sorghum receiving postemergence yi...
