Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts. We explore use of persistent homology, a topological method applied as filtration across simplicial complexes (or more simply, features spaces different spatial resolutions), overcome these limitations. The described isolates subsets measures relationship neighboring pixel densities shape. apply analysis 182,707 leaves, both...
Plants produce diverse metabolites to cope with the challenges presented by complex and ever-changing environments. These drive diversification of specialized within between plant species. However, we are just beginning understand how frequently new alleles arise controlling metabolite diversity geographic distribution these may be structured ecological demographic pressures. Here, measure variation in across a population 797 natural Arabidopsis thaliana accessions. We show that combination...
Gln is a key player in plant metabolism. It one of the major free amino acids that transported into developing seed and central for nitrogen However, natural variation its regulation interaction with other metabolic processes seeds remain poorly understood. To investigate latter, we performed genome-wide association study (mGWAS) Gln-related traits measured from dry Arabidopsis (Arabidopsis thaliana) diversity panel using all potential ratios between members Glu family as traits. This...
Free amino acids (FAAs) and protein-bound (PBAAs) in seeds play an important role seed desiccation, longevity, germination. However, the effect that water stress has on these two functional pools, especially when imposed during crucial setting stage is unclear. To better understand effects, we exposed Arabidopsis plants at to a range of limitation deprivation conditions then evaluated physiological, metabolic, proteomic parameters, with special focus FAAs PBAAs. We found response severe...
Abstract Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts. We explore use of persistent homology, a topological method applied across scales function, overcome these limitations. The described isolates subsets features measures spatial relationship neighboring pixel densities shape. apply analysis 182,707 leaves, both published unpublished, representing 141 plant families...
SUMMARY The ability of seeds to restore their amino acid content and composition after the elimination most abundant seed storage proteins (SSPs) is well‐documented, yet underlying mechanisms remain unclear. To better understand how compensate for major proteomic disruptions, we conducted a comprehensive analysis on an Arabidopsis mutant lacking three SSPs, cruciferins. Our initial findings indicated that carbon, nitrogen, sulfur levels, as well total protein oil content, remained unchanged...
Abstract Plants face a variety of challenges within their ever-changing environment. Diverse metabolites are central to the plants ability overcome these challenges. Understanding environmental and genetic factors influencing variation in specialized is key understand how survive develop under changing environments. Here we measure across population 797 natural Arabidopsis thaliana accessions. We show combination geography, parameters, demography, different processes that creates specific...
