Abstract Transcription factors (TFs) are major players in gene regulatory networks and interactions between TFs their target genes furnish spatiotemporal patterns of expression. Establishing the architecture requires gathering information on TFs, targets genome, corresponding binding sites. We have developed GRASSIUS (Grass Regulatory Information Services) as a knowledge-based Web resource that integrates promoters across grasses. In its initial implementation, consists two separate, yet...
This study assessed the production, land use, environmental impacts, and energy balance associated with ethanol biodiesel production in Argentina, Brazil, Colombia, Guatemala. These countries are considered developing economies produced 97% of biofuel Latin America, achieving 46 billion liters 2019. The implementation public policies (ie. RenovaBio, LCFS frameworks) to stimulate adoption low-carbon fuels may encourage production. Hence, official data for each country were used quantify...
Because of the economical relevance sugarcane and its high potential as a source biofuel, it is important to understand how this crop will respond foreseen increase in atmospheric [CO(2)]. The effects increased [CO(2)] on photosynthesis, development carbohydrate metabolism were studied (Saccharum ssp.). Plants grown at ambient (approximately 370 ppm) elevated 720 during 50 weeks open-top chambers. plants under CO(2) showed, end such period, an about 30% photosynthesis 17% height, accumulated...
Sucrose content is a highly desirable trait in sugarcane as the worldwide demand for cost-effective biofuels surges. Sugarcane cultivars differ their capacity to accumulate sucrose and breeding programs routinely perform crosses identify genotypes able produce more sucrose. mature internodes reach around 20% of culms dry weight. Genotypes populations reflect genetic program may display contrasting growth, development, physiology, all which affect carbohydrate metabolism. Few studies have...
Abstract Background Sugarcane is an increasingly economically and environmentally important C4 grass, used for the production of sugar bioethanol, a low-carbon emission fuel. originated from crosses Saccharum species noted its unique capacity to accumulate high amounts sucrose in stems. Environmental stresses limit enormously sugarcane productivity worldwide. To investigate transcriptome changes response environmental inputs that alter yield we cDNA microarrays profile expression 1,545 genes...
Abstract Understanding the complex interactions among food security, bioenergy sustainability, and resource management requires a focus on specific contextual problems opportunities. The United Nations’ 2030 Sustainable Development Goals place high priority energy security; plays an important role in achieving both goals. Effective security programs begin by clearly defining problem asking, ‘What can be done to assist people at risk?’ Simplistic global analyses, headlines, cartoons that...
Bioenergy has been under intense scrutiny over the last ten years with significant research efforts in many countries taking place to define and measure sustainable practices. We describe here main challenges policy issues provide recommendations for scaling up bioenergy approaches globally. The 2016 Intended Nationally Determined Contributions (INDCs defined UN Framework Convention on Climate Change) (UNFCCC) Conference of Parties (COP21) will not reach global Greenhouse Gas (GHG) emission...
ABSTRACT Background Sugarcane cultivars are polyploid interspecific hybrids of giant genomes, typically with 10–13 sets chromosomes from 2 Saccharum species. The ploidy, hybridity, and size the genome, estimated to have >10 Gb, pose a challenge for sequencing. Results Here we present gene space assembly SP80-3280, including 373,869 putative genes their potential regulatory regions. alignment single-copy in diploid grasses indicates that could resolve 2–6 (up 15) homo(eo)logs 99.1%...
Many plant species of great economic value (e.g., potato, wheat, cotton and sugarcane) are polyploids. Despite the essential roles autopolyploid plants in human activities, our genetic understanding these is still poor. Recent progress instrumentation biochemical manipulation has led to accumulation an incredible amount genomic data. In this study, we demonstrate for first time a successful analysis highly polyploid genome (sugarcane) by quantitative single-nucleotide polymorphism (SNP)...
Sugarcane is the source of sugar in all tropical and subtropical countries becoming increasingly important for bio-based fuels. However, its large (10 Gb), polyploid, complex genome has hindered based breeding efforts. Here we release largest most diverse set sugarcane sequences to date, as part an on-going initiative provide a genomic information resource, with ultimate goal producing gold standard genome. Three hundred seventeen chiefly euchromatic BACs were sequenced. A reference one...
Bioenergy is an important and feasible option for mitigating global warming climate change. However, large-scale land-use change (LUC) to expand bioenergy crops, such as sugarcane, raises concerns about the potential negative environmental socioeconomic side effects. Such effects are context-specific, depending on LUC scenario management practices, several co-benefits can be attained. We reviewed literature discussed how best practices affect key components of sustainability (e.g., soil...
ABSTRACT When Dictyostelium cells starve they arrest their growth and induce the expression of genes necessary for development. We have identified characterized a protein kinase, YakA, that is essential proper regulation both events. Amino acid sequence functional similarities indicate YakA homolog Yak1p, growth-regulating kinase in S. cerevisiae. Purified expressed E. coli able to phosphorylate myelin basic protein. YakA-null are smaller cell cycle accelerated relative wild-type cells....
Abstract Sugarcane is a proven biofuel feedstock and accounts for about 40% of the production worldwide. It has more favorable energy input/output ratio than that corn, other major feedstock. The rich resource genetic diversity plasticity autopolyploid genomes offer wealth opportunities application genomics technologies to address fundamental questions in sugarcane towards maximizing biomass production. In workshop on engineering held at Rutgers University, we identified research areas...
Sugarcane is a highly productive crop used for centuries as the main source of sugar and recently to produce ethanol, renewable bio-fuel energy source. There increased interest in this due impending need decrease fossil fuel usage. has polyploid genome. Expressed sequence tag (EST) sequencing significantly contributed gene discovery expression studies associate function with sugarcane genes. A significant amount data exists on regulatory events controlling responses herbivory, drought,...

Background Drought is a major abiotic stress that affects crop productivity worldwide. Sugarcane can withstand periods of water scarcity during the final stage culm maturation, which sucrose accumulation occurs. Meanwhile, prolonged drought cause severe plant losses. Methodology/Principal Findings In previous study, we evaluated transcriptome drought-stressed plants to better understand sugarcane responses drought. Among up-regulated genes was Scdr1 (sugarcane drought-responsive 1). The aim...

ABSTRACT When nutrients are depleted, Dictyostelium cells undergo cell cycle arrest and initiate a developmental program that ensures survival. The YakA protein kinase governs this transition by regulating the cycle, repressing growth-phase genes inducing genes. mutants have shortened do not development. A suppressor of yakA reverses most defects yakA− cells, but none their growth was identified. inactivated gene, pufA, encodes member Puf family translational regulators. Upon starvation,...
