Reduction Of Phakopsora Pachyrhizi Infection On Soybean Through Host- And Spray-Induced Gene Silencing, Dongfang Hu, Zhi Yuan Chen, Chunquan Zhang, Mala Ganiger

Faculty Publications

Asian soybean rust (ASR), caused by the obligate fungal pathogen Phakopsora pachyrhizi, often leads to significant yield losses and can only be managed through fungicide applications currently. In the present study, eight urediniospore germination or appressorium formation induced P. pachyrhizi genes were investigated for their feasibility to suppress ASR through a bean pod mottle virus (BPMV)-based host-induced gene silencing (HIGS) strategy. Soybean plants expressing three of these modified BPMV vectors suppressed the expression of their corresponding target gene by 45%–80%, fungal biomass accumulation by 58%–80%, and significantly reduced ASR symptom development in soybean leaves after the plants were inoculated with …

A Note On Species Richness And The Variance Of Epidemic Severity, Peter Shaffery, Bret D. Elderd, Vanja Dukic

Faculty Publications

© 2020, Springer-Verlag GmbH Germany, part of Springer Nature. The commonly observed negative correlation between the number of species in an ecological community and disease risk, typically referred to as “the dilution effect”, has received a substantial amount of attention over the past decade. Attempts to test this relationship experimentally have revealed that, in addition to the mean disease risk decreasing with species number, so too does the variance of disease risk. This is referred to as the “variance reduction effect”, and has received relatively little attention in the disease-diversity literature. Here, we set out to clarify and quantify some …

Improving Estimates For Discrete Polynomial Averages, Rui Han, Vjekoslav Kovač, Michael T. Lacey, José Madrid, Fan Yang

Faculty Publications

For a polynomial P mapping the integers into the integers, define an averaging operator ANf(x):=1N∑k=1Nf(x+P(k)) acting on functions on the integers. We prove sufficient conditions for the ℓp-improving inequality ‖ANf‖ℓq(Z)≲P,p,qN-d(1p-1q)‖f‖ℓp(Z),N∈N,where 1 ≤ p≤ q≤ ∞. For a range of quadratic polynomials, the inequalities established are sharp, up to the boundary of the allowed pairs of (p, q). For degree three and higher, the inequalities are close to being sharp. In the quadratic case, we appeal to discrete fractional integrals as studied by Stein and Wainger. In the higher degree case, we appeal to the Vinogradov Mean Value Theorem, recently established …

Multiscale-Spectral Gfem And Optimal Oversampling, Ivo Babuška, Robert Lipton, Paul Sinz, Michael Stuebner Jun 2020

Multiscale-Spectral Gfem And Optimal Oversampling, Ivo Babuška, Robert Lipton, Paul Sinz, Michael Stuebner

Faculty Publications

In this work we address the Multiscale Spectral Generalized Finite Element Method (MS-GFEM) developed in Babuška and Lipton (2011). We outline the numerical implementation of this method and present simulations that demonstrate contrast independent exponential convergence of MS-GFEM solutions. We introduce strategies to reduce the computational cost of generating the optimal oversampled local approximating spaces used here. These strategies retain accuracy while reducing the computational work necessary to generate local bases. Motivated by oversampling we develop a nearly optimal local basis based on a partition of unity on the boundary and the associated A-harmonic extensions.

Classification Of Super-Modular Categories By Rank, Paul Bruillard, César Galindo, Siu Hung Ng, Julia Y. Plavnik, Eric C. Rowell, Zhenghan Wang Jun 2020

Classification Of Super-Modular Categories By Rank, Paul Bruillard, César Galindo, Siu Hung Ng, Julia Y. Plavnik, Eric C. Rowell, Zhenghan Wang

Faculty Publications

We pursue a classification of low-rank super-modular categories parallel to that of modular categories. We classify all super-modular categories up to rank = 6, and spin modular categories up to rank = 11. In particular, we show that, up to fusion rules, there is exactly one non-split super-modular category of rank 2, 4 and 6, namely PSU(2)4k+ 2 for k = 0,1 and 2. This classification is facilitated by adapting and extending well-known constraints from modular categories to super-modular categories, such as Verlinde and Frobenius-Schur indicator formulae.

Despite correlations between low vitamin D levels and diabetes incidence/severity, supplementation with vitamin D has not been widely effective in improving glucose parameters. This may be due to a lack of knowledge regarding how low vitamin D levels physiologically affect glucose homeostasis. We have previously shown that the brain may be a critical area for vitamin D-mediated action on peripheral glucose levels. However, the mechanisms for how vitamin D acts in the brain are unknown. We utilized a multimodal approach to determine the mechanisms by which vitamin D may act in the brain. We first performed an unbiased search (RNA-sequencing) …

Projecting Stand Survival And Basal Area Based On A Self-Thinning Model For Chinese Fir Plantations, Xiongqing Zhang, Quang V. Cao, Hanchen Wang, Aiguo Duan, Jianguo Zhang

Faculty Publications

The self-thinning rule has played a critical role in controlling stand stocking and modeling stand development in forest stands. Chinese fir (Cunninghamia lanceolata) is a native and fast-growing tree species used for timber production and is widely grown in southern China. Effective management of this important tree species requires accurate and reasonable predictions of stand growth and survival. Remeasured data from 48 plots distributed in Fujian, Jiangxi, Guangxi, and Sichuan provinces were used to develop models to predict stand survival and basal area based on the self-thinning trajectories. These trajectories were constructed using a self-thinning slope of -1.605, as suggested …

Exercise Plus Caloric Restriction Lowers Soluble Rage In Adults With Chronic Kidney Disease, Steven K. Malin, Sankar D. Navaneethan, Ciaran E. Fealy, Amanda Scelsi, Hazel Huang, Michael Rocco, John P. Kirwan Jun 2020

Exercise Plus Caloric Restriction Lowers Soluble Rage In Adults With Chronic Kidney Disease, Steven K. Malin, Sankar D. Navaneethan, Ciaran E. Fealy, Amanda Scelsi, Hazel Huang, Michael Rocco, John P. Kirwan

Division of Basic Science Faculty Publications

Introduction: The incidence of chronic kidney disease (CKD) has increased in recent years. CKD is associated with obesity, type 2 diabetes, and cardiovascular disease, although the mechanism remains unclear. Elevated soluble form of the receptor for advanced glycation end products (RAGE) is related to proinflammatory signaling pathways that may promote diabetic nephropathy and vascular dysfunction. Because lifestyle modification reduces systematic inflammation in adults with obesity and hyperglycaemia, the hypothesis that exercise plus caloric restriction would lower soluble RAGE in adults with CKD was tested in this study. Methods: Eight adults (n = 6 females; age: 56.3 ± 2.8 y; BMI: …
