IGC Proceedings (1977-2023)

Tetraploid ruzigrass (Brachiaria ruziziensis) have been obtained by colchicine treatment of in vitro apical meristems and embryogenic calli. The colchicine treatment consisted of culturing apical meristem on MS basal medium containing 6.0 mg L^-1 6-benzylaminopurine (BAP) and 0.05-0.20% colchicine for 8, 14, 20 and 26 h. After treated by colchicine, apical meristems were transferred onto former medium without colchicine for 4 weeks. Surviving apical meristems were induced multiple roots on MS basal medium containing 2.0 mg L^-1 BAP. The ploidy level of plants after colchicine treatment was determined by flow cytometry. Apical meristems treated with 0.05% …

Growth Performance And Yield Of Three Brachiaria Cultivars Subjected To Different Eco-Climatic Zones Of Tanzania, Ismail S. Selemani

IGC Proceedings (1977-2023)

Replacement of high quality (perennial forage) with low quality (annual forage) due to the effects of climate change has resulted into low milk production in Tanzania to 4.5L which is below the genetic potential of producing at least 15L of milk per cow per day. Though high yield fodder grasses such as Brachiaria have been recommended as climate smart fodder grass, little information has been documented in Tanzania particularly with respect to the growth performance of these grasses across different eco-climatic zones. The current study determine the performance and yield of three cultivars of Brachiaria (Brachiaria brizantha cv. Piata, …

Differences In Urochloa Hybrids And Cultivars Biomass Production In Several Sites In Western Kenya, S. Mwendia, A. O. Notenbaert, D. M. Mwangi, R. Odhiambo, I. Ogutu, A. Juma

IGC Proceedings (1977-2023)

Forage production is at the core of improved livestock productivity, especially in sub Saharan Africa. The genetic potential of existing animals remains underutilized due to limited forage quality and quantity. Albeit wide range of forage germplasm that exists, little data is available for identifying suitable genotypes, matched to specific environments and production systems. Due to the spatial and temporal diverse environments in which livestock production happens, multi-locational screening of forage production and characterizing genotype by environment interaction is key. We selected seven Urochloa (Syn. Brachiaria) genotypes comprising three hybrids and four cultivars and established them in on-farm trials in …

Identification And Analysis Of Flowering Time Candidate Genes Of Dactylis Glomerata L., X. Q. Zhang, G. Y. Feng, L. K. Huang, X. X. Zhao, Z. F. Yang

IGC Proceedings (1977-2023)

Orchardgrass (Dactylis glomerata L.) is an important forage grass for cultivating livestock worldwide. Heading date is a surrogate measure of flowering time and is strongly correlated with the yield and quality of forage grasses. Here, we identified 210 flowering-related genes in orchardgrass by BLASTP. In addition, our integrated analysis of transcriptome, quantitative trait locus (QTL), and bulked segregant analysis (BSA) provided insights into the genetic network regulating flowering time. The results revealed that four main candidate genes may participate in flowering time control, including one FT-like gene and three MADS-box genes. Expression investigation between the early-flowering and late-flowering phenotype …

Warm-Season Legumes – Challenges And Constraints To Adapting Warm-Season Legumes To Transition Zone Climates With Examples From Arachis, G. M. L. Assis, José C. B. Dubeux Jr.

IGC Proceedings (1977-2023)

Grass pastures in monoculture are the predominant system in transition zone climates, where warm-season perennial grasses are usually cultivated. Mixed grass-legume pastures are worldwide recognized for having advantages over pure stands, including pasture longevity, N input from biological fixation, efficient nutrient cycling, and greater animal production. The genus Arachis encompasses important and successful warm-season forage legume species cultivated in mixed pastures or in pure stands. Arachis pintoi and Arachis glabrata are potential tropical forage species that can be used in transition zone climates. Mixed pastures with these legumes have been shown to be resilient systems, able to withstand short-term perturbations, …

Breeding Cows Body Condition And Dry Matter Availability In Natural Pastures Under Rotational System, Dinah Pereira Rodrigues, Giuliano Teixeira Da Silva, Paulo Elias Borges Rodrigues, Alex Fabiano Fernandes Gomes, Gustavo Kruguer Gonçalves, Leonardo De Melo Menezes

IGC Proceedings (1977-2023)

The livestock production in Rio Grande do Sul is based on natural pastures, which suffer great productive seasonality throughout the year, especially due to the quantitative and qualitative deficit that it goes through in the winter months. The existing dynamic between the animal and the forage is fundamental for a better reproductive performance of the brood cows, and consequently an increase of the productivity of beef cattle. The calf herd generation is, certainly, the fundamental element of the full cycle livestock. Knowing the potentiality and understanding the dynamism of the natural fields is a fundamental condition for the choice of …

Neoage Clocks - Epigenetic Clocks To Estimate Post-Menstrual And Postnatal Age In Preterm Infants., Stefan Graw, Marie Camerota, Brian S. Carter, Jennifer Helderman, Julie A. Hofheimer, Elisabeth C. Mcgowan, Charles R. Neal, Steven L. Pastyrnak, Lynne M. Smith, Sheri A. Dellagrotta, Lynne M. Dansereau, James F. Padbury, Michael O'Shea, Barry M. Lester, Carmen J. Marsit, Todd M. Everson

Manuscripts, Articles, Book Chapters and Other Papers

Epigenetic clocks based on DNA methylation (DNAm) can accurately predict chronological age and are thought to capture biological aging. A variety of epigenetic clocks have been developed for different tissue types and age ranges, but none have focused on postnatal age prediction for preterm infants. Epigenetic estimators of biological age might be especially informative in epidemiologic studies of neonates since DNAm is highly dynamic during the neonatal period and this is a key developmental window. Additionally, markers of biological aging could be particularly important for those born preterm since they are at heightened risk of developmental impairments. We aimed to …

Crossing The Great Divide: Bridging The Researcher–Practitioner Gap To Maximize The Utility Of Remote Sensing For Invasive Species Monitoring And Management, Kelsey Parker, Arthur Elmes, Peter Boucher, Richard A. Hallett, John E. Thompson, Zachary Simek, Justin Bowers, Andrew B. Reinmann

Advanced Science Research Center

Invasive species are increasingly present in our ecosystems and pose a threat to the health of forest ecosystems. Practitioners are tasked with locating these invasive species and finding ways to mitigate their spread and impacts, often through costly field surveys. Meanwhile, researchers are developing remote sensing products to detect the changes in vegetation health and structure that are caused by invasive species, which could aid in early detection and monitoring efforts. Although both groups are working towards similar goals and field data are essential for validating RS products, these groups often work independently. In this paper, we, a group of …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background: The small tyrosine kinase inhibitors (TKIs) subversively altered the lung cancer treatments, but patients will inevitably face the therapy resistance and disease recurrence. We aim to explore the potential roles of non-coding RNAs in sensitizing the TKIs effects.

Methods: Multiple cellular and molecular detections were applied to confirm the mechanistic regulations and intracellular connections.

Results: We explored the specific gene features of candidates in association with resistance, and found that m6A controlled the stemness of EMT features through METTL3 and YTHDF2. The miR-146a/Notch signaling was sustained highly activated in a m6A dependent manner, and the m6A regulator of YTHDF2 …

Linking Demand With Supply For Tropical Forage Genetic Resources To Reach Impact At Scale, M. Peters, S. Burkart, U. Ohmstedt, C. Castiblanco, E. Stern, A. Nicolayevsky, K. Enciso, M. Díaz, S. Mwendia, S. Douxchamps, A. O. Notenbaert, B. Lukuyu, K. Fuglie

IGC Proceedings (1977-2023)

Over the last decades a wealth of information on tropical forage genetic resources has been collated and is accessible to users ranging from farmers, development practitioners and researchers to decision makers and academia, e.g. through online tools such as Tropical Forages: An interactive selection tool (www.tropicalforages.info). However, while genetic diversity is being conserved by international gene banks, adoption of improved tropical forages is still far from reaching its full potential. Major bottlenecks in our view include lack of awareness of available forage genetic resources, confirmation of adaptation in a wide range of bio-physical, socio-economic, political and cultural contexts …
