Aspen Leaves As A "Chemical Landscape" For Fungal Endophyte Diversity - Can Nitrogen And Herbivory Shape The Community Composition In Controlled Conditions?, Johanna Witzell, Vicki Huizu Guo Decker, Marta Agostinelli, Carmen Romeralo Tapia, Michelle Cleary, Benedicte Riber Albrectsen Dec 2022

Aspen Leaves As A "Chemical Landscape" For Fungal Endophyte Diversity - Can Nitrogen And Herbivory Shape The Community Composition In Controlled Conditions?, Johanna Witzell, Vicki Huizu Guo Decker, Marta Agostinelli, Carmen Romeralo Tapia, Michelle Cleary, Benedicte Riber Albrectsen

Aspen Bibliography

The endophytic microbiome may influence the ecological performance of plants, including forest trees. Various abiotic and biotic factors may shape the endophyte communities directly but also indirectly, by modifying the quality of host plants as a substrate. We hypothesized that potentially antifungal or fungistatic condensed tannins (CTs) would determine the quality of aspen (Populus tremula) leaves as a substrate for endophytic fungi. By subjecting the plants to nitrogen fertilization (N) or herbivory (H; leaf beetles) we aimed to change the internal “chemical landscape”, especially the CT levels, in aspen leaves. We expected that this would lead to changes in the …

New Semi-Dwarfing Alleles With Increased Coleoptile Length By Gene Editing Of Gibberellin 3-Oxidase 1 Using Crispr-Cas9 In Barley (Hordeum Vulgare L.), Jingye Cheng, Camilla Hill, Yong Han, Tianhua He, Xingguo Ye, Sergey Shabala, Ganggang Guo, Meixue Zhou, Ke Wang, Chengdao Li

Grain and Other Field Crops Research Articles

The green revolution was based on genetic modification of the gibberellin (GA) hormone system with “dwarfing” gene mutations that reduces GA signals, conferring shorter stature, thus enabling plant adaptation to modern farming conditions. Strong GA-related mutants with shorter stature often have reduced coleoptile length, discounting yield gain due to their unsatisfactory seedling emergence under drought conditions. Here we present gibberellin (GA) 3-oxidase1 (GA3ox1) as an alternative semi-dwarfing gene in barley that combines an optimal reduction in plant height without restricting coleoptile and seedling growth. Using large-scale field trials with an extensive collection of barley accessions, we showed that a natural …

Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, Kelly Mercier, Chris Teutsch, Ray Smith, Kenny Burdine, Edwin Ritchey, Eric Vanzant Dec 2022

Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, Kelly Mercier, Chris Teutsch, Ray Smith, Kenny Burdine, Edwin Ritchey, Eric Vanzant

Journal of Extension

This study examined economic implications of planting summer annual mixtures of grasses, legumes, and forbs at varying nitrogen rates. No differences in yield occurred between the three mixtures, indicating that mixtures with lowest seed cost will be most economical. Applying N resulted in yield increases of 12.26 lb DM per lb N applied. Although yield responses to N were positive, sensitivity analyses showed that applying N resulted in positive net returns only when hay prices were high and N prices were low. When utilization rates are accounted for, enterprise budgets determined grazing to be 18% cheaper to implement than haying.

Oxidation is one of the most critical processes in food systems. It has an impact on a variety of dietary ingredient interactions, resulting in both desired and unwanted results. It was found in many studies that high concentrations of synthetic antioxidants may havesome carcinogenic effects in some animals, thus natural antioxidants would be analternative to synthetic antioxidants in food. These natural antioxidants can be present in any plant part, including grains, fruits, leaves, nuts, seeds, roots and barks. Many studies showed that there is an inverse relationship between the dietary intake of medicinal plants rich in antioxidants and the prevalence …

A Stealth Health Approach To Dietary Fibre, P. Stephen Baenziger, Katherine Anna Frels, Steve Greenspan, Julie Jones, Alison Lovegrove, Devin J. Rose, Peter Shewry, Rod Wallace

Department of Agronomy and Horticulture: Faculty Publications

Average dietary fibre intakes have increased little in the past twenty years in many countries, including the USA1 . Multi-million-dollar campaigns promoting fruits, vegetables, whole grains and other foods high in fibre have delivered only small changes in diets2 , and consumers have not changed from traditional staples to whole-grain options3 . UK millers report that consumption of whole-wheat bread has actually declined over the past decade (P. Shewry, personal communication). In the US, white flour, which is lower in fibre than whole-wheat flour, accounts for nearly 40% of the fibre intake4 . We believe that …
