Turkish Journal of Agriculture and Forestry

Citrus is one of the most important and widely cultivated fruit crops globally. However, its productivity is increasingly threatened by various diseases, with bacterial infections being particularly the most destructive. Among these, citrus canker, caused by Xanthomonas axonopodis pv. citri (Xac), poses a significant challenge, requiring effective management strategies. Traditional approaches have shown limited success, but nanotechnology has emerged as a promising alternative for disease control. In this study, Xanthomonas spp. was isolated from two locations: Koont Farm and the National Agricultural Research Centre (NARC) citrus orchards in Islamabad, Pakistan. The isolates were identified through morpho-biochemical methods. Moreover, three Bacillus …

Turkish Journal of Agriculture and Forestry

Individuals of the genus Xiphinema were recovered from soil samples collected during citrus surveys in south-eastern Türkiye. Morphological examination using light microscopy identified the species as X. brevicolle. The female individuals measured 2000–2050 μm in length, and displayed a slightly flattened lip region, an amphidelphic reproductive system with two well-developed branches, and a short conoid tail ending in a rounded tip. These morphometric and morphological features were consistent with those of previously described X. brevicolle specimens. For molecular confirmation, the D2–D3 segment of the 28S rDNA was amplified using the D2AD3B primer pair, and sequenced; the resulting sequence has been …

Microglial Expression Of Serotonin Receptors Reveals Parallel Regulation Of 5-Ht2b And Bdnf In The Rat Hippocampus, Andrei Turkin, Maria Sidorova, Ekaterina Kurilova, Natalia Alenina, Oksana Tuchina, Friederike Klempin

School of Graduate Studies Faculty Publications

Growing evidence suggests that psychiatric disorders are characterized by a prolonged inflammatory state, which may influence the efficacy of compounds targeting serotonin. Serotonin is a key signaling molecule in neuroplasticity of the adult hippocampus and involved in antidepressant action. Recent in vitro studies indicate the neurotransmitter may also facilitate the response to inflammation and potentially modulate microglial function towards neuroprotection. Using Tph2−/− rats depleted of brain serotonin, we examined microglial expression of various serotonin receptors (5-HTRs) in vivo in both the hippocampus and prefrontal cortex and assessed mRNA levels of cytokines and brain-derived neurotrophic factor (BDNF). We observed age-dependent and …

Faculty Journal Articles

A new species of functionally dioecious bush tomato from the “Solanum dioicum + S. echinatum group” of Solanum subgenus Leptostemonum is described. Solanum nectarifolium Martine & Brennan, sp. nov., is a member of the taxonomically challenging Solanum dioicum W.Fitzg. species complex in Australia and differs from other species in the group by the presence of prominent and conspicuous extrafloral nectaries on the abaxial leaf surfaces, a tinge of purple on the new growth and young fruiting calyces, and curved prickles on young stems. Although fairly well represented in herbarium collections, this new taxon has historically been treated as a …

Batf2 Is A Glutamine-Responsive Tumour Suppressor Required For Type-I Interferon-Dependent Anti-Tumour Immunity, Wang Gong, Hülya F Taner, Yuesong Wu, Yumin He, Xingwu Zhou, Zaiye Li, Xin Hu, Charisse Ursin, Kala Chand Debnath, Kohei Okuyama, Qiang Hu, Christopher R Donnelly, Felipe Nör, Chamila D Perera, Emily Bellile, Arash Yunesi, Zhiqian Zhai, Mei Zhao, Wanqing Cheng, Zackary R Fitzsimonds, Luke Broses, Jiaqian Li, Shadmehr Demehri, Deepak Nagrath, Gregory T Wolf, Andrew G Sikora, Yanbao Yu, Haitao Wen, Lei Wei, Steven B Chinn, Jeffrey N Myers, Shizuo Akira, Yuying Xie, James J Moon, Yu Leo Lei

Faculty, Staff and Student Publications

Recent evidence highlights the significance of a new type of tumour suppressors, which are not frequently mutated but inhibited by metabolic cues in cancers. Here, we identify BATF2 as a tumour suppressor whose expression is epigenetically silenced by glutamine in Head and Neck Squamous Cell Carcinomas (HNSCC). BATF2 correlates with type-I interferon and Th1 signatures in human HNSCC, with correlation coefficients even stronger than those of the positive control, STING. The phosphorylation of BATF2 at serine 227 promotes the oligomerization of STING. BATF2 deficiency or high glutamine levels result in higher oxygen consumption rates and metabolic profiles unfavorable for …

Faculty, Staff and Student Publications

Hepatocellular carcinoma (HCC), the common liver cancer, exhibits higher incidence in males. Here, we report that mice lacking bile acid (BA) regulators, Farnesoid X Receptor (FXR also termed NR1H4) and Small Heterodimer Partner (SHP also termed NR0B2), recapitulate the sex difference in liver cancer risk. Since few therapeutic options are available, we focused on understanding the intrinsic protection afforded to female livers. Transcriptomic analysis in control and NR1H4 and NR0B2 double knockout livers identified female-specific changes in metabolism, including amino acids, lipids, and steroids. To assess translational relevance, we examined if transcriptomic signatures obtained from this murine HCC model correlate …

Food Science Faculty Articles and Research

Fresh produce is highly perishable, necessitating various postharvest treatments to minimize quality loss, extend shelf-life, and facilitate international trade. This study investigated the potential of a single low-dose gamma irradiation treatment as an alternative to commercially used chemical treatments for protecting ‘Granny Smith’ apples against insect pests and postharvest disorders. ‘Granny Smith’ apples harvested in 2019 and 2020 were treated with gamma irradiation at doses of 240 or 860 Gray (Gy) or with commercial chemical applications of 1-methylcyclopropene (1-MCP), diphenylamine (DPA), or methyl bromide (MeBr). The impact on fruit quality, physiology, and the development of postharvest disorders was evaluated after …

Pressure Field Estimation From 2d-Piv Measurements: A Case Study Of Fish Suction-Feeding, Jensine C. Coggin, Duvall Dickerson-Evans, Erin E. Hackett, Roi Gurka

Physics and Engineering Science

Particle image velocimetry (PIV) flow measurements are common practice in laboratory settings in a wide variety of fields involving fluid dynamics, including biology, physics, engineering, and medicine. Dynamic fluid pressure is a notoriously difficult property to measure non-intrusively, yet its variation is a driving flow force and critical to model correctly. Techniques have been developed to estimate the pressure from velocity and velocity gradient measurements. Here, we highlight a novel application of boundary conditions when applying such pressure estimation techniques based on two-dimensional PIV data; the novel method is especially relevant to problems with complex boundary conditions. As such, it …
