Abstract Key message Here, we provide an updated set of guidelines for naming genes in wheat that has been endorsed by the research community. The last decade seen a proliferation genomic resources wheat, including reference- and pan-genome assemblies with gene annotations, which new opportunities to detect, characterise, describe influence traits interest. expansion genetic information supported growth community catalysed strong interest control agronomically important traits, such as...
The adverse effects of heat on plant yield strongly depend its duration and the phenological stage crops when occurs. To clarify these two aspects stress, systematic research was conducted under controlled conditions 101 wheat cultivars various geographic origin. Different durations stress (5, 10 15 days) were applied starting from three developmental stages (ZD49: booting stage, ZD59: heading, ZD72: 6th day after heading). Various morphological, yield-related traits physiological parameters...
Durum wheat (Triticum durum Desf.) is a tetraploid cereal grown in the medium to low-precipitation areas of Mediterranean Basin, North America and South-West Asia. Genomics applications have potential boost exploitation genetic resources advance understanding genetics important complex traits (e.g. resilience environmental biotic stresses). A dense accurate consensus map specific for T. will greatly facilitate mapping, functional genomics marker-assisted improvement. High quality genotypic...
Heading of cereals is determined by complex genetic and environmental factors in which genes responsible for vernalization photoperiod sensitivity play a decisive role. Our aim was to use diagnostic molecular markers determine the main allele types VRN-A1, VRN-B1, VRN-D1, PPD-B1 PPD-D1 worldwide wheat collection 683 genotypes investigate effect these alleles on heading field. The dominant VRN-B1 VRN-D1 were present at low frequency. PPD-D1a photoperiod-insensitive carried 57 % cultivars most...
ABSTRACT Low temperatures are required to regulate the transition from vegetative reproductive growth via a pathway called vernalization. In wheat, vernalization predominantly involves cold upregulation of floral activator VERNALIZATION1 (VRN1). Here, we have used an extreme response, identified through studying ambient temperature responses, reveal complexity inputs into VRN-A1, with allelic inter-copy variation at gene expansion VRN-A1 modulating these effects. We find that repressors...
Abstract Background Understanding the adaptation of cereals to environmental conditions is one key areas in which plant science can contribute tackling challenges presented by climate change. Temperature and day length are main regulators flowering drivers temperate cereals. The major genes that control time barley response cues VRNH1 , VRNH2 VRNH3 PPDH1 PPDH2 (candidate gene HvFT3 ). These from vernalization photoperiod pathways show complex interactions promote still not understood fully....
Winterhardiness is a complex trait that involves low temperature tolerance (LTT), vernalization sensitivity, and photoperiod sensitivity. Quantitative loci (QTL) for these traits were first identified using biparental mapping populations; candidate genes all have since been characterized. In this research we used set of 148 accessions consisting advanced breeding lines from the Oregon barley ( Hordeum vulgare L. subsp ) program selected cultivars extensively phenotyped genotyped with single...
In addition to its role in vernalization, temperature is an important environmental stimulus determining plant growth and development. We used factorial combinations of two photoperiods (16H, 12H) three levels (11, 18 25 °C) study the responses 19 wheat cultivars with established genetic relationships. Temperature produced more significant effects on development than photoperiod, strong genotypic components. Wheat genotypes PPD-D1 photoperiod sensitive allele were temperature; their was...
The response to vernalization and the expression of genes associated with responses (VRNH1, VRNH2, VRNH3) photoperiod (PPDH1 PPDH2) were analysed in four barley (Hordeum vulgare L.) lines: 'Alexis' (spring), 'Plaisant' (winter), SBCC058, SBCC106 (Spanish inbred lines), grown under conditions short days (VSD) or no long (NVLD). genotypes differ VRNH1. Their growth habits correlated level VRNH1 length intron 1. behaved as expected. SBCC058 showed an intermediate habit flowered relatively late...
Ambient temperatures are increasing due to climate change. Cereal crops development and production will be affected consequently. Flowering time is a key factor for adaptation of small grain cereals and, therefore, exploring developmental responses barley rising required. In this work, we studied phasic growth, inflorescence traits related yield, in eight near isogenic lines (Hordeum vulgare L.) differing at the VRN-H1, VRN-H2 PPD-H1 genes, representing different growth habits. The were...
Abstract Thirty‐nine barley varieties of different origin, representing growth types, were included in a series experiments aimed at analysing the variability vernalization response, photoperiod sensitivity and earliness per se establishing types ecoclimatic adaptability using multivariate analysis. In case spring there was no correlation between any three traits. For winter barleys, negative found response se. Vernalization showed positive correlation. Among large variations apparent...
The effects of synchronous photo (16 h daylength) and thermo (2 °C daily fluctuation) cycles on flowering time were compared with constant light temperature treatments using two barley mapping populations derived from the facultative cultivar 'Dicktoo'. 'Dicktoo'בMorex' (spring) population (DM) segregates for functional differences in alleles candidate genes VRN-H1, VRN-H3, PPD-H1, PPD-H2. first loci are associated vernalization response latter photoperiod sensitivity.

One option to achieving greater resiliency for barley production in the face of climate change is explore potential winter and facultative growth habits: both types, low temperature tolerance (LTT) vernalization sensitivity are key traits. Sensitivity short-day photoperiod a desirable attribute types. In order broaden our understanding genetics these phenotypes, we mapped quantitative trait loci (QTLs) identified candidate genes using genome-wide association studies (GWAS) panel composed 882...
Heat stress during the grain-filling period has a substantial effect on embryo development, and size chemical composition of grain. The lines doubled haploid population arising from cross between heat-sensitive (Plainsman V) heat-tolerant (Mv Magma) wheat variety were analysed to determine how these changes influenced germination kernels formed heat initial development seedlings. early grain main spike had significant influence yield components, which differed however for side spikes....
