Genome size varies widely, even among closely related species, yet much less is known about chromosome size variation. Here we use the fourth chromosome of Drosophila, also known as the "Muller F element" or "dot chromosome", as a model to investigate chromosome-specific size expansion. The F element of most Drosophila species is small (∼1.3 Mb) and almost entirely heterochromatic, yet harbors approximately 80 protein-coding genes. Here, we study D. kikkawai, D. takahashii, D. ananassae, and D. bipectinata, whose F elements are 2- to 15-fold larger in size compared to D. melanogaster. Through manual gene curation and comparative genomic analysis, we …

Faculty, Staff and Students Publications

Loss-of-function mutations in methyl-CpG binding protein 2 (MECP2) cause Rett syndrome. While we know that MeCP2 binds to methylated cytosines on DNA, the full breadth of the molecular mechanisms by which MeCP2 regulates gene expression remains incompletely understood. Here, using a genetic modifier screen, we identify the super elongation complex, a P-TEFb–containing elongation factor that releases promoter-proximally paused RNA polymerase II, as a genetic interactor of MECP2. MeCP2 physically interacts with SEC subunits and directly binds AFF4, the scaffold of the SEC, via the transcriptional repression domain. Furthermore, MeCP2 facilitates the binding of AFF4 on a subset …

Faculty Publications

Wheat stripe rust (Puccinia striiformis f. sp. tritici, Pst) poses a catastrophic threat to global food security. While MADS-box transcription factors regulate development and abiotic stress, their roles in plant-pathogen immunity remain enigmatic. In this study, we identified TaMADS2, a Pst-induced MADS-box gene, as a positive regulator of wheat resistance. Functional analyses demonstrated that TaMADS2 overexpression significantly enhanced Pst resistance, whereas its knockdown rendered wheat more susceptible. Further investigation revealed that TaMADS2 interacts with trichome birefringence-like protein 21 (TaTBL21) to activate glycerol kinase-like (TaGKL) expression. Silencing TaGKL in wild-type or TaMADS2-overexpressing lines …

Enhancement Of Aeration And Activated Sludge Processes Using Micronanobubbles For Efficient Wastewater Treatment, Marwa Ahmed Abdelhamid

Thesis/ Dissertation Defenses

Aeration is considered one of the most reliable and efficient processes in wastewater treatment. However, conventional aeration systems show low performance with respect to the gas transfer during the treatment process. This poses a challenge in maintaining sufficient dissolved oxygen (DO) concentrations essential for the treatment. The use of micronanobubbles (MNBs) in the aeration process has been proposed as effective tool in water and wastewater treatment owing to their stability and longevity. MNBs’ stability is a distinctive property resulting from several mechanisms, including the repulsion force due to charged surfaces that helps bubbles to resist coalescence/bursting. MNBs’ longevity is represented …
