Nitrogen (N) in the agricultural production system influences many aspects of agroecosystems and several critical ecosystem services widely depend on N availability soil. Cumulative changes regional may lead to global environmental changes. Thus, soil status agriculture is importance strategize its most efficient use. also one susceptible macronutrients loss, such as ammonia volatilization (NH3), nitrous oxide (N2O) emissions, nitrate leaching (NO3), etc. Any form losses from systems can be...
The major forces driving farm-level production for the ever-growing global population have relied upon mechanized farming techniques, synthetic inputs, and developing high-yielding crop varieties. Recently, however, there has been a gradual shift toward sustainable approaches addressing potential use of beneficial traits soil-plant microbiome to establish food supply as well maintain soil plant health. intricate relationship complex often faces difficulty in efficient translation broad...
Cold stress (CS) affects the survivability, geographical distribution, and yield stability of crops. Suitable management agronomic practices can minimize crop losses associated with cooler environments. However, alone can't support plants adequately to withstand harsh cold. Therefore, exploring cold stress-responsive factors such as genetic, epigenetic, physiological, cellular is crucial. This report discusses on effect, signal perception, transduction, gene expression, molecular phenomena...
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi Syd., is a widespread disease of [ Glycine max (L.) Merr.] with the potential to cause serious economic losses.

A population 117 recombinant inbred lines (RILs) cross Dillon (tan lesion) × Hyuuga (red‐brown [RB] rated for ASR in field and inoculated P. greenhouse. RB gene mapped between Satt460 Satt307 on linkage group (LG)‐C2....
Abstract Current knowledge of yield potential and best agronomic management practices for perennial bioenergy grasses is primarily derived from small‐scale short‐term studies, yet these studies inform policy at the national scale. In an effort to learn more about how perform across multiple locations years, U.S. Department Energy ( US DOE )/Sun Grant Initiative Regional Feedstock Partnership was initiated in 2008. The objectives were (1) provide a wide range information feedstock selection...
A greenhouse study was conducted to explore the effect of various rates potassium sulfate (K2SO4) nanoparticles on alfalfa (Medicago sativa L.) growth and physiological response under salt stress. One salt-tolerant genotype (Mesa-Sirsa) one salt-sensitive (Bulldog 505) were selected based germination planted in pots containing 2 kg sand. The two genotypes subjected 0 6 dS·m-1 levels using CaCl2·2H2O: NaCl (2:1) mixed with Hoagland solution. Three K2SO4 nanoparticle treatments consisting of,...
Understanding key adaptation traits is crucial to developing new cultivars with broad adaptations. The main objective of this research understand the genetic basis winter hardiness (WH) and fall dormancy (FD) in alfalfa association between two traits. QTL analysis was conducted a pseudo-testcross F1 population developed from contrasting FD (3010 = 2 CW 1010 10). mapping evaluated three replications at locations (Watkinsville Blairsville, GA). levels showed low moderate correlations WH...
Predicting alfalfa biomass and crop yield for livestock feed is important to the daily lives of virtually everyone, many features data from this domain combined with corresponding weather can be used train machine learning models prediction. In work, we different varieties multiple years in Kentucky Georgia, compared impact feature selection methods on (ML) trained predict yield. Linear regression, regression trees, support vector machines, neural networks, Bayesian nearest neighbors were...
Abstract Leveraging the use of multiplex multi-omic networks, key insights into genetic and epigenetic mechanisms supporting biofuel production have been uncovered. Here, we introduce RWRtoolkit, a generation, exploration, statistical package built for R command line users. RWRtoolkit enables efficient exploration large highly complex biological networks generated from custom experimental data and/or publicly available datasets, is species agnostic. A range functions can be used to find...
Interspecific hybridization in fungi has gained attention for its role fungal evolution and potential commercial applications. Successful can enhance fitness facilitate adaptation to new ecological niches. However, the genomic consequences of remain poorly understood. Epichloe is a genus that includes both non-hybrid hybrid species, with hybrids forming through parasexual reproducing asexually. Some are significance, as they colonize Lolium arundinaceum (Schreb.) Darbysh., crucial forage...
The genetic and genomic basis of flowering time biomass yield in alfalfa (Medicago sativa L.) remains poorly understood mainly due to the autopolyploid nature species lack adequate resources. We constructed linkage maps using genotyping-by-sequencing (GBS) based single dose allele (SDA) SNP mapped timing (TOF), spring (SY), cumulative summer (CSB) a pseudo-testcross F1 population derived from fall dormant (3010) non-dormant (CW 1010) cultivars. analyzed quantitative trait loci (QTL) identify...
Abstract Bioenergy production often focuses on the aboveground feedstock for conversion to fuel and other materials. However, belowground component is crucial soil carbon sequestration, greenhouse gas fluxes, ecosystem function. Roots maximize marginal lands by acquiring resources mediating processes through interactions with microbial community. This world challenging observe quantify; however, there are unprecedented opportunities using current methodologies bring roots, microbes, into...
Economically viable production of biobased products and fuels requires high-yielding, high-quality, sustainable process-advantaged crops, developed using bioengineering or advanced breeding approaches. Understanding which crop phenotypic traits have the largest impact on biofuel economics sustainability outcomes is important for targeted feedstock development. Here, we evaluated biomass yield cell-wall composition across a large natural variant population switchgrass (Panicum virgatum L.)...
Molybdenum (Mo) is a critical micronutrient for nitrogen (N) fixation in legumes. Low pH limits the availability of Mo, thereby reducing nodulation and N fixation. This study investigates effect Mo supplementation on alfalfa its correlation with root shoot biomass low-pH soil. Three experiments were conducted greenhouse, involving 14 genotypes subjected to four different treatments, unlimed soil (5.2) applied (lithium (Li)−Mo+), without (Li−Mo−), limed (pH 7.3) (Li+Mo+), (Li+Mo−).
