The effect of constant (18 degrees C) and daily fluctuating (18/16 degrees C) temperature with a long photoperiod was also examined in a set of barley varieties including winter, facultative and spring barleys. Dicktoo with facultative growth habit was more sensitive to unfavourable conditions than Kompolti korai with winter growth habit; the flowering of Dicktoo was significantly delayed by sub- and supra-optimal temperatures and low light intensity accompanied by higher or fluctuating temperatures. The optimal temperature at flowering was also significantly lower for Dicktoo than for Kompolti korai (16.0 degrees C vs. 21.0 degrees C, respectively). Plant development was the fastest when there was no fluctuating environmental factor in the growing conditions and was significantly delayed with application of photo cycle. The addition of thermo cycle to photo cycle had an even stronger delaying effect. Facultative barleys were the most sensitive, followed by winter barleys, while spring barleys the least sensitive to the introduction of thermo cycle.}, keywords = {GENE; TRAITS; TIME; WHEAT; VERNALIZATION; PLANT DEVELOPMENT; PHOTOPERIOD; VRN-H2 LOCUS; MAJOR DETERMINANT; MAPPING POPULATION}, year = {2008}, eissn = {1588-256X}, pages = {205-215} } @article{MTMT:1129202, title = {Effects of photo and thermo cycles on flowering time in barley: a genetical phenomics approach}, url = {https://m2.mtmt.hu/api/publication/1129202}, author = {Karsai, Ildikó and Szucs, P and Kőszegi, Béla and Hayes, PM and Casas, A and Bedő, Zoltán and Veisz, Ottó Bálint}, doi = {10.1093/jxb/ern131}, journal-iso = {J EXP BOT}, journal = {JOURNAL OF EXPERIMENTAL BOTANY}, volume = {59}, unique-id = {1129202}, issn = {0022-0957}, abstract = {The effects of synchronous photo (16 h daylength) and thermo (2 degrees C daily fluctuation) cycles on flowering time were compared with constant light and temperature treatments using two barley mapping populations derived from the facultative cultivar 'Dicktoo'. The 'Dicktoo'x'Morex' (spring) population (DM) segregates for functional differences in alleles of candidate genes for VRN-H1, VRN-H3, PPD-H1, and PPD-H2. The first two loci are associated with the vernalization response and the latter two with photoperiod sensitivity. The 'Dicktoo'x'Kompolti korai' (winter) population (DK) has a known functional polymorphism only at VRN-H2, a locus associated with vernalization sensitivity. Flowering time in both populations was accelerated when there was no fluctuating factor in the environment and was delayed to the greatest extent with the application of synchronous photo and thermo cycles. Alleles at VRN-H1, VRN-H2, PPD-H1, and PPD-H2-and their interactions-were found to be significant determinants of the increase/decrease in days to flower. Under synchronous photo and thermo cycles, plants with the Dicktoo (recessive) VRN-H1 allele flowered significantly later than those with the Kompolti korai (recessive) or Morex (dominant) VRN-H1 alleles. The Dicktoo VRN-H1 allele, together with the late-flowering allele at PPD-H1 and PPD-H2, led to the greatest delay. The application of synchronous photo and thermo cycles changed the epistatic interaction between VRN-H2 and VRN-H1: plants with Dicktoo type VRN-H1 flowered late, regardless of the allele phase at VRN-H2. Our results are novel in demonstrating the large effects of minor variations in environmental signals on flowering time: for example, a 2 degrees C thermo cycle caused a delay in flowering time of 70 d as compared to a constant temperature.}, keywords = {PHOTOPERIOD; GROWTH HABIT; VRN-H2 LOCUS; HEADING DATE; TEMPERATE CEREALS; MAJOR DETERMINANT; MAPPING POPULATION; VERNALIZATION GENES; PSEUDO-RESPONSE-REGULATOR; HORDEUM-VULGARE L.}, year = {2008}, eissn = {1460-2431}, pages = {2707-2715} }
