The stem rust resistance gene Sr24 is effective against most races of Puccinia graminis f. sp. tritici, including race TTKS (syn. Ug99), and used widely in commercial wheat cultivars worldwide. In 2006, susceptible infection responses were observed on lines carrying a field screening nursery at Njoro, Kenya. We derived 28 single-pustule isolates from samples collected the 2006 Njoro nursery. evaluated for virulence 16 North American differential lines; Sr24, Sr31, Sr38, SrMcN; cultivar with...
Abstract Stem or black rust, caused by Puccinia graminis tritici , has historically severe losses to wheat ( Triticum aestivum ) production worldwide. Successful control of the disease for over three decades through use genetic resistance resulted in a sharp decline research activity recent years. Detection and spread East Africa race TTKS, commonly known as Ug99, is high significance most cultivars currently grown its likely migration path, i.e. North Arabian Peninsula then Middle Asia, are...
Stem rust, caused by Puccinia graminis f. sp. tritici, historically was one of the most destructive diseases wheat and barley. The disease has been under effective control worldwide through widespread use host resistance. A number stem rust resistance genes in have characterized for their reactions to specific races P. tritici. Adult plant responses race TTKS (also known as Ug99) monogenic lines Sr genes, a direct measurement effectiveness given gene, not investigated any extent. This report...
The growing popularity of Unmanned Aerial Vehicles (UAVs) in recent years, along with decreased cost and greater accessibility both UAVs thermal imaging sensors, has led to the widespread use this technology, especially for precision agriculture plant phenotyping. There are several camera systems market that available at a low cost. However, their efficacy accuracy various applications not been tested. In study, three commercially UAV cameras, including ICI 8640 P-series (Infrared Cameras...
Microsatellite DNA markers are widely used in genetic research. Their use, however, can be costly and throughput is sometimes limited. The objective of this paper to introduce a simple, low‐cost, high‐throughput system that detects amplification products from microsatellite by nondenaturing polyacrylamide gel electrophoresis. This capable separating fragments differ as little two base pairs. electrophoresis unit holds vertical 100‐sample gels allowing standards samples 96‐well plate analyzed...
High-throughput phenotyping platforms (HTPPs) provide novel opportunities to more effectively dissect the genetic basis of drought-adaptive traits. This genome-wide association study (GWAS) compares results obtained with two Unmanned Aerial Vehicles (UAVs) and a ground-based platform used measure Normalized Difference Vegetation Index (NDVI) in panel 248 elite durum wheat (Triticum turgidum L. ssp. Desf.) accessions at different growth stages water regimes. Our suggest increased ability...
Vernalization response and low-temperature acclimation are survival mechanisms that cereals have evolved to cope with stress. Both responses similar optimum temperature ranges for induction, they controlled by genetic systems interrelated. It has also been suggested the completion of vernalization is responsible gradual loss in tolerance observed winter maintained long periods time at temperatures range acclimation. In present study, two experiments were conducted objective clarifying...
Improvement of crop water use efficiency (CWUE), defined as yield per volume used, is an important goal for both management and breeding. While many technologies have been developed measuring in studies, rarely these techniques applied at the scale breeding plots. The objective was to develop a high-throughput methodology quantifying cotton trial Maricopa, AZ, USA 2016 2017, using evapotranspiration (ET) measurements from co-located irrigation evaluate approach. Approximately weekly...
The cDNA clone pWG1 represents a gene, designated cor39, from Triticum aestivum L. cv Winoka (a winter wheat) that is related to cold-regulated Arabidopsis thaliana (Heyn) cor47. In vitro transcription/translation experiments in conjunction with DNA sequence analysis indicated cor39 encodes hydrophilic polypeptide of 39 kD (isoelectric point 7.5), COR39. composed primarily two sequences, each which repeated six times. One sequence, lysine rich, occurs COR47 (the encoded by cor47) and group...
The recently developed OPtical TRapezoid Model (OPTRAM) has been successfully applied for watershed scale soil moisture (SM) estimation based on remotely-sensed shortwave infrared (SWIR) transformed reflectance (TRSWIR) and the normalized difference vegetation index (NDVI). This study is aimed at evaluation of OPTRAM field precision agriculture applications using ultrahigh spatial resolution optical observations obtained with one world’s largest robotic phenotyping scanners located in...
The Transportation Energy Resources from Renewable Agriculture Phenotyping Reference Platform (TERRA-REF) provides a data and computation pipeline responsible for collecting, transferring, processing distributing large volumes of crop sensing genomic genetically informative germplasm sets. primary source these is field scanner system built over an experimental at the University Arizona Maricopa Agricultural Center. uses several different sensors to observe dense collection frequency with...
Osmotic adjustment (OA) is a major component of drought resistance in crops. The genetic basis OA wheat and other crops remains largely unknown. In this study, 248 field-grown durum elite accessions grown under well-watered conditions, underwent progressively severe treatment started at heading. Leaf samples were collected heading 17 days later. following traits considered: flowering time (FT), leaf relative water content (RWC), osmotic potential (ψs), OA, chlorophyll (SPAD), rolling (LR)....

Fusarium head blight (FHB), caused by graminearum Schwabe [teleomorph Gibberella zeae (Schwein.)], is a devastating disease that reduces yield, quality and economic value of wheat ( Triticum aestivum L.) barley Hordeum vulgare L.). The quantitative nature resistance tremendous expense phenotypic screening indicate the identification resistant genotypes in breeding populations might be expedited molecular markers. markers must polymorphic informative across for them to used breeders....

Abstract Chlorophyll fluorescence (ChlF) is a powerful non‐invasive technique for probing photosynthesis. Although proposed as method drought tolerance screening, ChlF has not yet been fully adopted in physiological breeding, mainly due to limitations high‐throughput field phenotyping capabilities. The light‐induced transient (LIFT) sensor recently shown reliably provide active data rapid and remote characterisation of plant photosynthetic performance. We used the LIFT quantify...
