Environmental stress is a major driver of ecological community dynamics and agricultural productivity. This especially true for soil water availability, because drought the greatest abiotic inhibitor worldwide crop yields. Here, we test genetic basis responses in model C4 perennial grasses, Panicum hallii, through population genomics, field-scale gene-expression (eQTL) analysis, comparison two complete genomes. While gene expression networks are dominated by local cis-regulatory elements,...
In light of the changes in precipitation and soil water availability expected with climate change, understanding mechanisms underlying plant responses to deficit is essential. Toward that end we have conducted an integrative analysis drought stress perennial C4 grass biofuel crop, Panicum virgatum (switchgrass). Responses drying re-watering were measured at transcriptional, physiological, metabolomic levels. To assess interaction moisture diel light: dark cycles, profiled gene expression...
Identifying the physiological and genetic basis of stress tolerance in plants has proven to be critical understanding adaptation both agricultural natural systems. However, many discoveries were initially made controlled conditions greenhouses or laboratories, not field. To test comparability drought responses across field greenhouse environments, we undertook three independent experiments using switchgrass reference genotype Alamo AP13. We analyzed gene expression variation four locations,...
Abstract Geographic patterns of within-species genomic diversity are shaped by evolutionary processes, life history and historical contemporary factors. New approaches can be used to infer the influence such factors on current distribution infraspecific lineages. In this study, we evaluated morphological as well genetic structure C4 grass Panicum hallii across its complex natural in North America. We sampled extensively range P. Mexico USA generate double-digestion restriction-associated DNA...
Understanding how and why genetic variation is partitioned across geographic space of fundamental importance to understanding the nature biological species. How geographical isolation local adaptation contribute formation ecotypically differentiated groups plants just beginning be understood through population genomic studies. We used whole genome sequencing combined with association study climate discover drivers differentiation in perennial C4 grass Panicum hallii.Sequencing 89 natural...
Collections of tissue samples stand as keystone sources molecular information to construct biodiversity knowledge, and are particularly useful in megadiverse countries. In 1998 the Humboldt Institute (<em>Instituto de Investigación Recursos Biológicos Alexander von Humboldt</em>) began a collection Colombian (IAvH-CT) aim this work is present diagnostic an historical narrative for that collection, constructed by compiling experiences on its management well organizing curating...
Abstract Appropriate flowering time is a crucial adaptation impacting fitness in natural plant populations. Although the genetic basis of variation has been extensively studied, its mechanisms nonmodel organisms and adaptive value field are still poorly understood. Here, we report new insights into effect on Panicum hallii, native perennial grass. Genetic mapping populations derived from inland coastal ecotypes identified quantitative trait loci (QTL) many exhibited extensive...
Abstract Flowering time is crucial for wild plant populations to adapt their local environments. Although the genetic basis of flowering variation has been studied in many species, its mechanisms non-model organisms and adaptive value field are still poorly understood. Here, we report new insights into effect on fitness Panicum hallii , a native perennial grass. We conducted mapping derived from representative inland coastal ecotypes identify QTL loci exhibited extensive QTL-by-environment...
