Department of Agronomy and Horticulture: Faculty Publications

Salinity has a significant negative impact on production of rice. To cope with the increased soil salinity due to climate change, we need to develop salt tolerant rice varieties that can maintain their high yield. Rice landraces indigenous to coastal Bangladesh can be a great resource to study the genetic basis of salt adaptation. In this study, we implemented a QTL analysis framework with a reciprocal mapping population developed from a salt tolerant landrace Horkuch and a high yielding rice variety IR29. Our aim was to detect genetic loci that contributes to the salt adaptive responses of the two …

On The Market For "Lemons": When Low Quality Does Not Drive High Quality Out Of The Market, Konstantinos Giannakas, Murray E. Fulton

Cornhusker Economics

In a research article published in Nature's Humanities and Social Sciences Communications (available at https://www.nature.com/articles/s4l 599-020-00658-w) we identify the conditions under which the introduction of a low -quality product does not drive its high-quality counterpart out of the market but, instead, ends-up coexisting with it. Using a theoretical framework of heterogeneous consumers and producers in the context of a market for quality- ( or vertically-) differentiated products supplied by producers differing in their production efficiency, we show that the equilibrium quality configuration in a market depends on both the unobservability of product quality by consumers and the relative costs …

Rice Chalky Grain 5 Regulates Natural Variation For Grain Quality Under Heat Stress, Anil Kumar Nalini Chandran, Jaspreet Sandhu, Larissa Irvin, Puneet Paul, Balpreet K. Dhatt, Waseem Hussain, Tian Gao, Paul E. Staswick, Hongfeng Yu, Gota Morota, Harkamal Walia

Department of Agronomy and Horticulture: Faculty Publications

Heat stress occurring during rice (Oryza sativa) grain development reduces grain quality, which often manifests as increased grain chalkiness. Although the impact of heat stress on grain yield is well-studied, the genetic basis of rice grain quality under heat stress is less explored as quantifying grain quality is less tractable than grain yield. To address this, we used an image-based colorimetric assay (Red, R; and Green, G) for genome-wide association analysis to identify genetic loci underlying the phenotypic variation in rice grains exposed to heat stress. We found the R to G pixel ratio (RG) derived from mature …

Department of Agronomy and Horticulture: Faculty Publications

Weeds compete with crops for soil moisture, along with other resources, which can impact the germination, growth, and seed production of weeds; however, this impact has not been systematically recorded and synthesized across diverse studies. To address this knowledge gap, a global meta-analysis was conducted using 1,196 paired observations from 86 published articles assessing the effect of water stress on weed germination, growth characteristics, and seed production. These studies were conducted and published during 1970 through 2020 across four continents (Asia, Australia, Europe, and North America). Imposed water stress was expressed as solution osmotic potential (ψsolution), soil water potential (ψsoil), …

Alfalfa Water Productivity And Yield Gaps In The U.S. Central Great Plains, Kaylin P. Fink, Patricio Grassini, Alexandre Rocateli, Leonardo M. Bastos, Jude Kastens, Luke P. Ryan, Xiaomao Lin, Andres Patrignani, Romulo P. Lollato

Department of Agronomy and Horticulture: Faculty Publications

Context: Yield gap (Yg) analyses using farmer-reported yield and management data have been performed for a number of annual grain crops, but it lacks for perennial forages. The U.S. accounts for 21 % of the global alfalfa production with a large rainfed area located in the central Great Plains, serving as an interesting case-study for Yg in perennial forages. Most existing alfalfa Yg analyses quantified the magnitude of the Yg but failed to identify associated management practices to reduce it. Challenging this analysis, a systematic benchmark for alfalfa water productivity [WP, kg dry matter per mm evapotranspiration (ETc)] that …

Agronomic And Quality Impact Of A Shortened Translocation For Wheat Streak Mosaic Virus Resistance, Mary J. Guttieri, Robert L. Bowden, Guorong Zhang, Scott Haley, Katherine Anna Frels, Gary L. Hein, Katherine W. Jordan

Department of Agronomy and Horticulture: Faculty Publications

Wheat streak mosaic virus (WSMV) is a mite-vectored virus with substantial economic impact on wheat production. One of the effective sources of resistance to WSMV, Wsm1, is carried on a translocation from Thinopyrum intermedium. The original whole arm form of this translocation (T4DL·4JsS) was highly effective against WSMV but carried a substantial yield penalty in the absence of the virus. Shorter recombinants of the Th. intermedium translocation are now available. This study characterized the agronomic performance of near-isogenic sib-pair families in 10 yield trials using one of these shortened T4DL·4DS-4J^sS translocations, named “rec213,” in the absence …

Compared with most flowers where the showy part comprises specialized leaves (petals) directly subtending the reproductive structures, most Zingiberaceae species produce showy ‘‘flowers’’ through modifications of leaves (bracts) subtending the true flowers throughout an inflorescence. Curcuma alismatifolia, belonging to the Zingiberaceae family, a plant species originating from Southeast Asia, has become increasingly popular in the flower market worldwide because of its varied and esthetically pleasing bracts produced in different cultivars. Here, we present the chromosome-scale genome assembly of C. alismatifolia ‘‘Chiang Mai Pink’’ and explore the underlying mechanisms of bract pigmentation. Comparative genomic analysis revealed C. alismatifolia contains a …

Assisted Migration Is Plausible For A Boreal Tree Species Under Climate Change: A Quantitative And Population Genetics Study Of Trembling Aspen (Populus Tremuloides Michx.) In Western Canada, Chen Ding, Jean S. Brouard

Aspen Bibliography

A novel method was tested for improving tree breeding strategies that integrate quantitative and population genetics based on range-wide reciprocal transplant experiments. Five reciprocal common garden tests of Populus tremuloides were investigated including 6450 trees across western Canada focusing on adaptation traits and growth. Both genetic parameters and home-site transplant models were evaluated. We found a genetic trade-off between growth and early spring leaf flush and late fall senescence. Coefficients of phenotypic variation (CVp) of cell lysis (CL), a measure of freezing injury, shrank from 0.28 to 0.10 during acclimation in the fall, and the CVp slope versus …

Don't Let The Past Sink Your Future, Timothy Meyer

Cornhusker Economics

Decision scientists have many algorithms for making decisions. These algorithms can be qualitative and subjective, such as following a 7-step process, to highly quantitative procedures like minimax regret, or linear programming. These techniques are very different from each other, but in one way they are very similar; they never, ever suggest the manager become emotional and use past decisions to guide the future.

Past decisions and events should guide decision-making. They help managers assign probabilities as well assessing performance. Viewing these events and situations as permanent paths is where sunk costs become problematic.

Includes discussions of four scenarios.

Building Soil By Building Community: How Can An Interdisciplinary Approach Better Support Community Needs And Urban Resilience, Erica L. Wohldmann, Yujuan Chen, Kirsten Schwarz, Susan D. Day, Richard V. Pouyat, Michelle Barton, Manny Gonez

Agricultural and Environmental Sciences Faculty Research

Given the interrelated problems of climate change, energy and resource scarcity, and the challenge of supporting critical natural systems in cities, urban dwellers may be exceptionally vulnerable to the impacts of climate change. While a number of programs and policies have been developed and implemented to help reduce the environmental and social impacts of climate change on communities, we argue that effective and sustainable programs must not only consider how the changing environment impacts communities, but also how communities interact with and impact the environment. Specifically, drawing on a case study of the needs assessment of the Healthy Soils for …

Comparative Transcriptomics Reveals Small Rna Composition And Differential Microrna Responses Underlying Interferon-Mediated Antiviral Regulation In Porcine Alveolar Macrophages, Jiuyi Li, Eric R. Sang, Oluwaseun Adeyemi, Laura C. Miller, Yongming Sang

Agricultural and Environmental Sciences Faculty Research

Previous studies have shown that interferon-mediated antiviral activity is subtype-dependent. Using a whole transcriptome procedure, we aimed to characterize the small RNA transcriptome (sRNA-Seq) and specifically the differential microRNA (miRNA) responses in porcine alveolar macrophages (PAMs) upon antiviral activation during viral infection and interferon (IFN) stimulation. Data showed that near 90% of the qualified reads of sRNA were miRNAs, and about 10% of the other sRNAs included rRNA, snoRNA, snRNA, and tRNA in order of enrichment. As the majority of sRNA (>98%) were commonly detected in all PAM samples under different treatments, about 2% sRNA were differentially expressed between …

The Viability Of Traditional Portuguese Olive Groves In The Alentejo Region Under A Sustainable Development Framework, Sydney Soloway

Independent Study Project (ISP) Collection

Portugal became self-sufficient in olive oil production in 2014 and produces 150% of its needs, which makes Portugal the world’s fourth-largest exporter (DeAndreis, 2022). Olive groves in Portugal were once estimated to be 70-80% low-input traditional type, but rapid intensification toward a predominantly intensive mode of agriculture has been extremely fast (Beaufoy, 2001, p. 22; Silveira et al., 2018, p. 248). The Alentejo region, despite its dry Mediterranean climate and a tradition of extensive, multi-functional agricultural systems, is now home to 85% of Portugal’s olive groves and responsible for 77% of the country’s olive oil production (Dawson, 2019; Silveira et …

“Hadithi Ya Matunda”: The Informal Fruit Economy On Unguja Island: A Study Of The Livelihoods Of Smallholder Producers, Intermediaries, And Sellers, Daisy Kettle

Independent Study Project (ISP) Collection

This is the story of fruit on Unguja Island. It illuminates the livelihoods of farmers, intermediaries, and sellers and each of their roles in the island’s fruit commodity chain. Linkages between these actors are known to play increasingly important roles in agricultural economies across the world due to their ability to create “multiplier effects” through networks of non-farm income opportunities (Wineman, 2020). Through interviews with 19 Zanzibaris who work in this trade network, I learned about the intricacies of these networks. My data revealed that the fruit flow chain on Unguja creates a network of extensive backward and forward economic …
