Pearl millet [Cenchrus americanus (L.) Morrone] is a staple food for more than 90 million farmers in arid and semi-arid regions of sub-Saharan Africa, India South Asia. We report the ∼1.79 Gb draft whole genome sequence reference genotype Tift 23D2B1-P1-P5, which contains an estimated 38,579 genes. highlight substantial enrichment wax biosynthesis genes, may contribute to heat drought tolerance this crop. resequenced analyzed 994 pearl lines, enabling insights into population structure,...
Genome-environment associations and phenotypic analyses may reveal the basis of environmental adaptation.
It was previously shown that pearl millet genotypes carrying a terminal drought tolerance quantitative trait locus (QTL) had lower transpiration rate (Tr; g cm−2 d−1) under well-watered conditions than sensitive lines. Here experiments were carried out to test whether this relates leaf abscisic acid (ABA) and Tr concentration at high vapour pressure deficit (VPD), leads efficiency (TE) differences. These traits measured in tolerant/sensitive genotypes, including near-isogenic lines...
Pearl millet, a key staple crop of the semi-arid tropics, is mostly grown in water-limited conditions, and improving its performance depends on how genotypes manage limited water resources. This study investigates whether control loss under non-limiting conditions involved terminal drought tolerance pearl millet. Two pairs tolerant×sensitive millet genotypes, PRLT 2/89-33–H77/833-2 863B-P2–ICMB 841-P3, near-isogenic lines (NILs), introgressed with quantitative trait locus (QTL) from donor...
In this paper, we describe the thought process and initial data behind development of an imaging platform (LeasyScan) combined with lysimetric capacity, to assess canopy traits affecting water use (leaf area, leaf area index, transpiration). LeasyScan is based on a novel 3D scanning technique capture continuously, scanner-to-plant concept increase throughput analytical scales combine gravimetric transpiration measurements. The paper presents how technology functions, are visualised via...
A pearl millet inbred germplasm association panel (PMiGAP) comprising 250 lines, representative of cultivated from Africa and Asia, elite improved open-pollinated cultivars, hybrid parental inbreds mapping population parents, was recently established. This study presents the first report genetic diversity in PMiGAP its exploitation for drought tolerance traits. For structure analysis, genotyped with 37 SSR CISP markers representing all seven linkage groups. it phenotyped yield components...
Pearl millet is a multipurpose grain/fodder crop of the semi-arid tropics, feeding many world's poorest and most undernourished people. Genetic variation among adapted pearl inbreds hybrids suggests it will be possible to improve grain micronutrient concentrations by selective breeding. Using 305 loci, linkage map was constructed QTLs for iron [Fe] zinc [Zn] using replicated samples 106 RILs (F6) derived from ICMB 841-P3 × 863B-P2. The grains RIL population were evaluated Fe Zn content...
Pearl millet [Pennisetum glaucum (L.) R. Br.] is the staple cereal of hottest, driest areas tropics and subtropics. Drought stress a regular occurrence in these regions, making tolerance an essential attribute new pearl cultivars. Recent breeding research has mapped several quantitative trait loci (QTLs) for components grain stover yield per se, as well maintenance, under terminal drought conditions. We report here evaluation QTLs possible selection criteria improving elite hybrid cultivar....
Pearl millet marker-assisted selection (MAS) programs targeting adaptation to variable postflowering moisture environments would benefit from quantitative trait loci (QTLs) that improve grain yield across the full range of conditions, rather than just in drought-stressed environments. This research was undertaken identify such QTLs an extensive (12-environment) phenotyping data set included both stressed and unstressed Genetic materials were test crosses 79 F2–derived F4 progenies a mapping...
Intuitively, access to water from the soil at key phenological stages is important for adaptation drought. This study aimed assess temporal pattern of extraction under terminal drought stress. Pearl millet genotypes with varying levels tolerance were grown in a lysimetric system volume and plant spacing similar field conditions. Water was monitored until maturity differing regimes. The yield did not differ among well-watered (WW) conditions, profile WW plants across all genotypes. In...
Background Acid soils comprise up to 50% of the world's arable lands and in these areas aluminum (Al) toxicity impairs root growth, strongly limiting crop yield. Food security is thereby compromised many developing countries located tropical subtropical regions worldwide. In sorghum, SbMATE, an Al-activated citrate transporter, underlies AltSB locus on chromosome 3 confers Al tolerance via release. Methodology Population structure was studied 254 sorghum accessions representative diversity...
Pearl millet plays a major role in food security arid and semi-arid areas of Africa India. However, it lags behind the other cereal crops terms genetic improvement. The recent sequencing its genome opens way to use modern genomic tools for breeding. Our study aimed at identifying components involved early drought stress tolerance as first step toward development improved pearl varieties or hybrids. A panel 188 inbred lines from West was phenotyped under well-irrigated conditions. We found...
Foxtail millet [Setaria italica (L.) P. Beauv.] is one among the most ancient crops of dryland agriculture. It second important crop millets grown for grains or forage. germplasm resources provide reservoirs novel alleles and genes improvement that have remained mostly unexplored. We genotyped a set 190 foxtail accessions (including 155 core collection) using genotyping-by-sequencing (GBS) rapid single nucleotide polymorphisms (SNP) characterization to study population genetics structure,...
