Deciphering Pleiotropic Effects: A Molecular Characterisation of the Foraging Gene in Drosophila melanogaster
… been a pivotal example of a single gene with natural variants that affect feeding-related phenotypes. One possible mode of action for foraging’s pleiotropy is through independent regulation of its gene products. Characterization of the foraging gene revealed 4 distinct promoters that produce …

Characterising the function and evolution of enhancers in Drosophila
… of binding sites and intervening sequences among natural variants of the Drosophila hb P2 enhancer. This suggests that by studying the mutations gained through evolution we can learn more about flexibility and constraints in enhancers and improve on our current knowledge. I then generated tools …

Genetic engineering of sorghum and switchgrass for improved biofuel production
… employment of ectopic ZmGA20ox, or selection for natural variants with high level expression of endogenous GA20ox are appropriate approaches to increase biomass production of switchgrass and possible other monocot biofuel crops. Additional contribution of this study is to optimize sorghum …

The impact of heterogeneity in stomatal anatomical characters on stomatal function and physiology in wheat
… interest in understanding plant adaptations and natural variants with interesting anatomical features are to assist in targeting traits for enhanced water-use efficiency and, moreover, crop productivity.sity (SD), size (SS) and pore aperture determine stomatal conductance (gs) where changes in …

Topics in Multiplicative and Probabilistic Number Theory
… Finally, we make some progress on some natural variants of Chowla's conjecture on sign patterns of the {+1, –1}-valued multiplicative functions. Some of the aforementioned results are joint work with O. Klurman, or with Y. Lamzouri.

Symbolic Evaluations Inspired by Ramanujan's Series for 1/pi
… We provide explicit closed-form expressions for natural variants of the above series. At the time of our research being conducted, up-to-date versions of Computer Algebra Systems such as Mathematica and Maple could not evaluate our introduced series, such as $$ \sum _{n=1}^{\infty } \frac{ …

The impact of common and rare human genetic variants on erythrocyte invasion by Plasmodium falciparum malaria parasites
… is genetically diverse, and some people carry natural variants that confer varying levels of protection against the disease. In recent years, several large-scale genome-wide association studies (GWAS) have identified novel human genetic variants (e.g., variants at the GYPA/B/E gene cluster) and …

Exploiting natural variation in Plantago seed composition for food and human health applications
… candidature to be less than ideal for screening natural variants.. Previously published methods were often incomplete, time-consuming, and unnecessarily wasteful of precious seed stocks. Instead the new method described in Chapter 3 can be used to extract fractions of mucilage from small …

Caratterizzazione strutturale e funzionale dei sistemi emoglobinici di due specie di pesci (Mugil cephalus e Ophisurus serpens) e di due varianti emoglobiniche umane (HbRoma e HbF-SS-Monserrato)
… funcional characterisation of human hemoglobins natural variants and those present in different animal species. We report the identification and characterisation of two new hemoglobin variant, never described before, that we have named HbF-Monserrato-Sassari [Gγ93(F9) Cys Arg] and Hb Roma …

USING ANALYTICAL METHODOLOGIES TO ASSESS THE ORGANOLEPTIC CHARACTER OF CITRUS ESSENTIAL OIL
Essential oils are natural products used to flavor food and beverages. With the increase in nutrition conscious consumers, manufacturers of food additives and food products are faced with the challenge of making healthy alternatives. In particular, food products going to market with label claims …

Molecular Probes for Biologically Important Molecules: A Study of Thiourea, Hydroxyl radical, Peroxynitrite and Hypochlorous acid
Numerous chemical species are important to the health of biological systems. Some species can be beneficial at low doses and harmful at high doses. Other species are highly reactive and trigger serious cell damage. Improved methods to detect the presence and activity of such species are needed. In …
