Sweetpotato [Ipomoea batatas (L.) Lam.] is a globally important staple food crop, especially for sub-Saharan Africa. Agronomic improvement of sweetpotato has lagged behind other major crops due to lack genomic and genetic resources inherent challenges in breeding heterozygous, clonally propagated polyploid. Here, we report the genome sequences its two diploid relatives, I. trifida triloba, show that these high-quality assemblies are robust references hexaploid sweetpotato. Comparative...
• Premise of the study: Morning glories are an emerging model system, and resolving phylogenetic relationships is critical for understanding their evolution. Phylogenetic studies demonstrated that largest morning glory genus, Ipomoea , not monophyletic, nine other genera derived from within . Therefore, systematic research focused on monophyletic tribe Ipomoeeae (ca. 650–900 species). We used whole plastomes to infer across Ipomoeeae. Methods: Whole were sequenced 29 species, representing...
Crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas] have the potential to contribute breeding objectives for this important root crop. Uncertainty in regard species boundaries and their phylogenetic relationships, limited availability germplasm with which perform crosses, difficulty introgression genes from has constrained utilization. Here we compile geographic occurrence data on relevant produce distribution models species. We then assess comprehensiveness ex...
Convolvulaceae is a family of c. 2,000 species, distributed across 60 currently recognized genera. It includes species high economic importance, such as the crop sweet potato (Ipomoea batatas L.), ornamental morning glories bindweeds (Convolvulus and dodders, parasitic vines (Cuscuta L.). Earlier phylogenetic studies, based predominantly on chloroplast markers or single nuclear region, have provided framework for systematic studies family, but uncertainty remains at level relationships among...
Understanding relationships among orchid species and populations is of critical importance for conservation. Target sequence capture has become a standard method extracting hundreds orthologous loci phylogenomics. Up-front cost time associated with design bait sets makes this prohibitively expensive many researchers. Therefore, we designed target kit to reliably across lineages.
Storage roots are an ecologically and agriculturally important plant trait that have evolved numerous times in angiosperms. primarily function to store carbohydrates underground as reserves for perennial species. In morning glories, storage well characterized the crop species sweetpotato, where starch accumulates roots. This starch-storage tissue proliferates, thicken accommodate additional tissue. times. The primary goal of this study is understand whether was through parallel evolution,...
(2786) Ipomoea L., Sp. Pl.: 159. 1 Mai 1753 [Convolvul.], nom. cons. Typus: I. triloba typ. prop. L. is the largest (650–900 species, depending on concept adopted) and most iconic genus in Convolvulaceae, a family of c. 1880 species (data from Staples, Convolvulaceae Unlimited, 2012 at: http//convolvulaceae.myspecies.info), including important crop sweetpotato, batatas (L.) Lam. (Tabl. Encycl. 1: 465. 1793), several ornamental commonly known as "bindweeds" or "morning glories" (Wilkin Kew...
Torreya taxifolia Arn. (Florida torreya) is a critically endangered (International Union for Conservation of Nature 3.1) conifer with very limited native range in the USA, occurring two counties Florida and one Georgia where it persists ravines along Apalachicola River. The species suffered major decline, ∼ 99% loss, beginning 1930s, total population estimated at 357,500 early 1900s decreasing to 1,000 individuals currently remaining wild. initial decline was attributed an unknown fungal...
Weeds represent a major cause of agricultural losses worldwide. Most weeds share common set life history characteristics that predispose them to weediness, two which are self-compatibility, allows for ease colonization through reproductive assurance, and high trait plasticity, tolerance wide variety environments abiotic conditions. However, self-fertilization typically comes at the cost inbreeding depression. This study investigates role depression plasticity under stress in tall...
Abstract A proposal to change the conserved type of Ipomoea was published in December 2020, and recommended by Nomenclature Committee 2023. This done light possible negative consequences for a name crop sweetpotato, which risk our would significantly minimize. Recently, Muñoz‐Rodríguez & al. have rebuttal this proposal, we respond here. The objections raised these authors focus as much on expertise credibility group merits arguments. In “rebuttal rebuttal”, scientific questions raised,...
The study of plant root growth in real time has been difficult to achieve an automated, high-throughput, and systematic fashion. Dynamic imaging roots is important order discover novel behaviors deepen our understanding how interact with their environments. We designed implemented the Generating Rhizodynamic Observations Over Time (GROOT) robot, high-throughput system that enables time-lapse 90 containers plants growing a clear gel medium over duration weeks months. uses low-cost, widely...
