  • Multiplicity of Carotene Patterns Derives from Competition Between
    www.nature.com/scientificreports OPEN Multiplicity of carotene patterns derives from competition between phytoene desaturase diversifcation and biological environments Mathieu Fournié1,2,3 & Gilles Truan1* Phytoene desaturases catalyse from two to six desaturation reactions on phytoene, generating a large diversity of molecules that can then be cyclised and produce, depending on the organism, many diferent carotenoids. We constructed a phylogenetic tree of a subset of phytoene desaturases from the CrtI family for which functional data was available. We expressed in a bacterial system eight codon optimized CrtI enzymes from diferent clades. Analysis of the phytoene desaturation reactions on crude extracts showed that three CrtI enzymes can catalyse up to six desaturations, forming tetradehydrolycopene. Kinetic data generated using a subset of fve purifed enzymes demonstrate the existence of characteristic patterns of desaturated molecules associated with various CrtI clades. The kinetic data was also analysed using a classical Michaelis–Menten kinetic model, showing that variations in the reaction rates and binding constants could explain the various carotene patterns observed. Competition between lycopene cyclase and the phytoene desaturases modifed the distribution between carotene intermediates when expressed in yeast in the context of the full β-carotene production pathway. Our results demonstrate that the desaturation patterns of carotene molecules in various biological environments cannot be fully inferred from phytoene desaturases classifcation but is governed both by evolutionary-linked variations in the desaturation rates and competition between desaturation and cyclisation steps. Carotenoids are organic pigments produced by plants, algae, fungi, and bacteria and can be subdivided into two families of molecules, carotenes and their oxidised counterparts, xanthophylls 1.

  • Defining the Role of Phytoene Synthase in Carotenoid Accumulation of High Provitamin a Bananas
    Defining the role of phytoene synthase in carotenoid accumulation of high provitamin A bananas By Bulukani Mlalazi Bachelor of Biotechnology Innovation (Hons.) A thesis submitted for the degree of Doctor of Philosophy at the Queensland University of Technology Centre for Tropical Crops and Biocommodities 2010 Abstract: Vitamin A deficiency (VAD) is a serious problem in developing countries, affecting approximately 127 million children of preschool age and 7.2 million pregnant women each year. However, this deficiency is readily treated and prevented through adequate nutrition. This can potentially be achieved through genetically engineered biofortification of staple food crops to enhance provitamin A (pVA) carotenoid content. Bananas are the fourth most important food crop with an annual production of 100 million tonnes and are widely consumed in areas affected by VAD. However, the fruit pVA content of most widely consumed banana cultivars is low (~ 0.2 to 0.5 µg/g dry weight). This includes cultivars such as the East African highland banana (EAHB), the staple crop in countries such as Uganda, where annual banana consumption is approximately 250 kg per person. This fact, in addition to the agronomic properties of staple banana cultivars such as vegetative reproduction and continuous cropping, make bananas an ideal target for pVA enhancement through genetic engineering. Interestingly, there are banana varieties known with high fruit pVA content (up to 27.8 µg/g dry weight), although they are not widely consumed due to factors such as cultural preference and availability. The genes involved in carotenoid accumulation during banana fruit ripening have not been well studied and an understanding of the molecular basis for the differential capacity of bananas to accumulate carotenoids may impact on the effective production of genetically engineered high pVA bananas.

    52th Annual Meeting Argentine Society for Biochemistry and Molecular Biology LII Reunión Anual Sociedad Argentina de Investigación en Bioquímica y Biología Molecular Pabellón Argentina. Universidad Nacional de Córdoba November 7-10, 2016 BIOCELL 40 (Suppl.1) 2016 - SAIB - 52th Annual Meeting Argentine Society for Biochemistry and Molecular Biology LII Reunión Anual Sociedad Argentina de Investigación en Bioquímica y Biología Molecular November 7th–10th, 2016 Córdoba, República Argentina Pabellón Argentina Universidad Nacional de Cordoba Cover Page: Confocal microscopy images of Arabidopsis thaliana root are displayed in the cover. The selected roots are expressing a GFP reporter of a mitotic cyclin (CYCB1;1-GFP, green), also they are counterstained with propidium iodide (IP, red) to display the cell structure. In order to follow the progression through the cell cycle phases, the root cells were synchronized in S phase using HU, and after pictures were taken every 2 hours. This type of experiment was also used to generate RNA samples to analyze the dynamics of different gene expression during the cell cycle. Inside the circle, which shows the cell cycle phases, images of cells expressing a histone fused to the fluorescent protein VENUS and stained with IP, are displayed. Those images allow following the steps of mitosis in vivo inside the root ( PL-P56: Identification of cell cycle regulators inplants, by Goldy, C; Ercoli, MF; Vena, R; Palatnik, J, Rodriguez, Ramiro E.)

The dominance of resistant strains has compelled malaria prone area [16]. The sufferings are due to massive loss of to the discovery and development of new and different modes-of- productive man hours. The violent cycle of malaria and poverty action. Current plasmodial drug discovery efforts remains lack continues in its most grave form in the developing nations where far-reaching set of legitimated drug targets. Prerequisite of these the poorest of poor cannot afford costly medication[1].Causative targets (or the pathways in which they function) is that they agent of human malaria is intracellular parasites of the genus prove to be crucial for parasite survival.

A third redox active group became very difficult in the battle against this parasite due to transfers the reducing equivalent from the apolar active site to the drug resistant Plasmodium falciparum [1].

  • Citrus Polyamines: Structure, Biosynthesis, and Physiological Functions

Since the first description of putrescine conjugate, feruloyl-putrescine (originally called subaphylline), from grapefruit leaves and juice, many research studies have highlighted the importance of PAs in growth, development, and other physiological processes in citrus plants. PAs appear to be involved in a wide range of physiological processes in citrus plants; however, their exact roles are not fully understood. Accordingly, in the present review, we discuss the biosynthesis of PAs in citrus plants, with an emphasis on the recent advances in identifying and characterizing PAs-biosynthetic genes and other upstream regulatory genes involved in transcriptional regulation of PAs metabolism. In addition, we will discuss the recent metabolic, genetic, and molecular evidence illustrating the roles of PAs metabolism in citrus physiology including somatic embryogenesis; root system formation,
