Status: 2020 This paper presents the investigation of the effects of beta radiation on common bean (Phaseolus vulgaris). Nothing Reported phytoalexin production, root architecture and gene expression was measured in elongating roots of Phaseolus vulgaris seedlings. Aerial roots grow above the ground, typically providing structural support. How have the results been disseminated to communities of interest?Results on the ICA-Bunsi x SXB450 cross were presented at the Bean Improvement Cooperative Biennial Meeting in East Lansing in November 2017. These effects were not corrected by the addition of the auxin 3-naphtalenacetic acid (NAA). Status: c) We evaluated a recombinant inbred population of the cross of ICA Bunsi and SXB 405, from the Mesoamerican genepool, to evaluate the effects of drought on productivity and its components, as related to pod photosynthate remobilization. 2019 We expect that this dataset will provide a deeper molecular understanding of breeding germplasm and deliver molecular tools for germplasm development, aiming to increase the efficiency of bean breeding programs.

Days to flowering, seed yield and seed weight were recorded in 2017. d) We developed three domesticated by wild backcrossed recombinant inbred line populations (BC1S4), using three wild accessions representing the extreme range of rainfall of the Mesoamerican wild bean distribution. There are many different types of specialized roots, but two of the more familiar types of roots include aerial roots and storage roots. Root growth of two drought tolerant and two drought sensitive bean (Phaseolus vulgaris L.) lines was compared at two locations in Colombia differing primarily in soil conditions.At Palmira, roots of drought tolerant lines reached a depth of 1.3 m, while drought sensitive lines only reached 0.8 m. We studied the pod harvest index (PHI), a measure of the partition of pod biomass to seed biomass, its components, and phenology. The population now consists of 960 lines, which will be evaluated in the field for the first time in Summer 2016. 40. Terminal drought was applied by irrigating until mid flowering, thus applying water stress at the pod filling stage. Most of the QTLs were detected in both methods, but not all of them.

In both years there were two treatments, full irrigation (4 events) and terminal drought conditions (first two irrigations). In root nodule subpopulations from different parts of the root system, nitrogenase activity was previously found to vary. The purpose of this study was to characterize fungal and oomycete species associated with root diseases of Phaseolus vulgaris, Vigna unguiculata, V. radiata and Vicia faba in Oman. 1999. The variation explained by these QTLs ranged from 0.6 to 5.4 % of the total variation and the additive effects ranged from -164 to 277 kg ha-1, with evidence for allelic series for certain QTLs. The influence of soil compaction on root and the symbiotic vesicular‐arbuscular mycorrhizal (VAM) fungal associations is essentially unknown. the embryonic region between cotyledons and radicle may also join the taproot in storing food. We estimated recombination rates within each chromosome using genetic and physical distance. Rasse, D., A.J.M. Yield, flowering time, seed weight, growth habit, canopy height, pod harvest index, and pod shattering were evaluated in 2016. Three different types of experiments were conducted. b) Whole genome sequencing was conducted on 16 common bean lines and the results were pooled with those obtained at the International Center for Tropical Agriculture (CIAT, Cali, Colombia). We evaluated the population for three years (2016 - 2018). Although the QTLs for yield were not stable across water/regime combinations, we detected three that were on the overall mean. It is the normal tap root modified to store the food material. We decided to genotype with this platform because the quality the data is higher and issues with missing data is lower that with genotyping by sequencing (GBS). Year Published: The eight parents were chose following several criteria: 1) they have to belong to the Mesoamerican gene pool to avoid unexpected hybrid lethality and other performance-reducing genetic interactions; 2) they have to be photoperiod-insensitive; and 3) they have to show traits involved in drought tolerance.

Two forms of glutamine synthetase (GS) have been purified to apparent homogeneity from the plant fraction of Phaseolus vulgaris root nod ules. Changes/Problems:We switched from Genotyping-by-Sequencing to SNP chips analysis to get a more reliable genotyping platform (fewer missing data per site). Compounds Exuded by Phaseolus vulgaris That Induce a Modification of Rhizobium etli Lipopolysaccharide Dominik M. Duelli and K. Dale Noel Department of Biology, Marquette University, Milwaukee, WI 53233, U.S.A. Evaluation of newly developed single nucleotide polymorphism markers within previously discovered quantitative trait loci for common bacterial blight and angular leaf spot provides improved specificity to tag sources of resistance to these diseases. Evaluation of nuclear DNA content and analysis of copy number variation revealed important differences in genomic content not only between P. vulgaris and the two other domesticated Phaseolus species, but also within P. vulgaris, affecting hundreds of protein-coding genomic regions. Root-microbe communication is another important process that characterizes the underground zone. For linkage analysis there are 3,198 polymorphic markers within the parental lines, an enough quantity for this analysis. The R. etli mutant was not impaired in its ability to form nitrogen-fixing nodules on Phaseolus vulgaris but it displayed slower nodulation kinetics relative to the wild-type strain.
