lucidating genotype-by-environment interactions and partitioning its contribution to phenotypic variation remains a challenge for plant scientists. We propose a framework that utilizes genome-wide markers to model genotype-specific shoot growth trajectories as a function of time and soil water availability. A rice diversity panel was phenotyped daily for 21 d using an automated, high-throughput image-based, phenotyping platform that enabled estimation of daily shoot biomass and soil water content. Using these data, we modeled shoot growth as a function of time and soil water content, and were able to determine the time point where an inflection in the growth trajectory occurred. We …

Voxel Carving-Based 3d Reconstruction Of Sorghum Identifies Genetic Determinants Of Light Interception Efficiency, Mathieu Gaillard, Chenyong Miao, James Schnable, Bedrich Benes
Department of Agronomy and Horticulture: Faculty Publications
Changes in canopy architecture traits have been shown to contribute to yield increases. Optimizing both light interception and light interception efficiency of agricultural crop canopies will be essential to meeting the growing food needs. Canopy architecture is inherently three-dimensional (3D), but many approaches to measuring canopy architecture component traits treat the canopy as a two-dimensional (2D) structure to make large scale measurement, selective breeding, and gene identification logistically feasible. We develop a high throughput voxel carving strategy to reconstruct 3D representations of sorghum from a small number of RGB photos. Our approach builds on the voxel carving algorithm to allow …

Heterosis, or hybrid vigour, is a predominant phenomenon in plant genetics, serving as the basis of crop hybrid breeding, but the causative loci and genes underlying heterosis remain unclear in many crops. Here, we present a large-scale genetic analysis using 5360 offsprings from three elite maize hybrids, which identifies 628 loci underlying 19 yield-related traits with relatively high mapping resolutions. Heterotic pattern investigations of the 628 loci show that numerous loci, mostly with complete–incomplete dominance (the major one) or overdominance effects (the secondary one) for heterozygous genotypes and nearly equal proportion of advantageous alleles from both parental lines, are the …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Persicaria perfoliata (L.) H. Gross (Polygonaceae; Mile-a-minute weed) is a rapid-growing invasive vine introduced from eastern Asia to northeastern United States in the 1930s. This vine has been invaded in disturbed areas and reforestation sites in 15 states in the U.S. and forms dense, monocultural patches that may inhibit natural forest regeneration. To control this weed, a host-specific biocontrol agent, Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) has been released in the P. perfoliata invaded states in the U.S. during the past 15 years. Currently, R. latipes is released by hand to the invaded area where the presence of the weed is …

Evolutionary Genomics Of Dynamic Sex Chromosomes In The Salicaceae, Ran Zhou
Graduate Theses, Dissertations, and Problem Reports (ETD)
Identifying the sex-determination region (SDR) and other genomic features of sex chromosomes are of great importance in the studies of the evolution of sex. However, the process of accurately identifying the size and location of the SDR is often difficult, even when a genomic sequence is available. This usually is hindered by large repetitive elements and a lack of recombination in the SDR. In this thesis, I assemble sex chromosomes with whole genomic sequencing data, identify SDRs and explore their genomic features in two sister species from the Salicaceae family. I also develop an interpretation of the lability of the …
The Endogenous L-Cysteine Desulfhydrase And Hydrogen Sulfide Participate In Supplemented Phosphorus-Induced Tolerance To Salinity Stress In Maize (Zea Mays) Plants, Cengi̇z Kaya, Muhammad Ashraf
Turkish Journal of Botany
Although phosphorus supplementation (SP) has been shown to improve salinity tolerance in plants, crosstalk between hydrogen sulfide (H2S) or L-cysteine desulfhydrase (LDES) and SP-induced salinity tolerance needs to be elucidated. Thus, prior to initiation of stress treatment, young seedlings were transferred to aqueous solution containing the scavenger of H2S, 0.1 mM hypotaurine (HT), or the inhibitor of LDES, 0.3 mM DL-propargylglycine (PAG), for 12 h. The plants grown under control (no NaCl added) or salinity stress (SS; 100 mM NaCl) were then supplemented with SP (2.0 mM in total) as KH2PO4 for 5 weeks. SS caused a significant decrease in …

Notes On The Genus Sauvetrea (Orchidaceae, Maxillariinae), With A Description Of A New Species, Dariusz L. Szlachetko, Natalia Oledrzynska, Monika M. Lipinska
Turkish Journal of Botany
The genus Sauvetrea Szlach. (Orchidaceae) was segregated from Maxillaria sensu lato in 2007. It embraces a group of from 10 to nearly 20 species, all initially defined as Maxillaria sect. Trigonae. Sauvetrea can be easily distinguished from closely related Rhetinantha M.A.Blanco by the lip callus. During the revision of the materials stored in AMES we came across specimens collected by Vargas in Peru, which were initially identified by Schweinfurth as Maxillaria brachypetala Schltr. We compared Vargas's discovery with the protologue of the latter species and other Sauvetrea, but it does not fit the description of any genus representatives known so …

Turkish Journal of Botany
In the present study, microalgal biomass (Anabeana circinalis and Scenedesmus quadricauda) was used as biofertilizer in cucumber cultivation. The response of cucumber growth characters to microalgal biofertilizer was evaluated. Moreover, rhizosphere microbial diversity and community composition of cucumber was analyzed through 16S rRNA high-throughput Illumina sequencing data. The results showed that microalgal biomass as biofertilizer significantly promoted height, number of leaves and flower buds, and stem diameter of cucumber. The application of a high concentration of S. quadricauda to soil raised the diversity of rhizosphere fungi of cucumber. The rhizosphere microbial community of cucumber also responded to microalgal biofertilizer. The …
