ABSTRACT.- Spot blotch (SB), caused by Bipolaris sorokiniana is becoming an important barley disease in humid, temperate growing regions, including Uruguay. The narrow genetic base of current donors of resistance and recent changes in pathogen virulence have driven the search for novel sources of resistance. In this study, a diverse collection of 39 barley genotypes was evaluated for SB resistance, and genetic relationships, population structure, and haplotype diversity were investigated using 27 simple sequence repeats (SSRs) and eight sequence-tagged sites (STS) markers linked to nine QTL for SB resistance located on chromosomes 1H, 2H, 3H, 4H, and 7H. Fourteen barley genotypes expressed high and moderate SB resistance at seedling and adult plant stages. Distance and model-based cluster analyses revealed that the 14 selected lines clustered in four groups consistent with geographical origin and pedigree relatedness. Reference SB resistant haplotypes were poorly represented. Based on these results, we suggest that these 14 lines are likely candidates to carry novel genes or alleles for SB resistance. Further research may expand the understanding of the genetic architecture of this trait. © 2024 Informa UK Limited, trading as Taylor & Francis Group. |

ABSTRACT.
Grapefruits are highly susceptible to developing chilling injury (CI) symptoms during postharvest storage at low temperatures. The role of ethylene in the response of citrus fruits to low temperature is still controversial and whether the hormone is a defense response to cope with the cold-induced damage is not fully understood. Moreover, little is known about the ethylene signaling cascade in coldsensitive citrus fruit under chilling conditions. Therefore, the aim of this work was to study the transcriptional regulation of ethylene biosynthesis, perception and response during storage at 2°C of the yellow ?Marsh? and the red ?Star Ruby? grapefruits. To better understand the regulation of cold- or chilling-induced ethylene production, the effect of the ethylene action inhibitor, 1-MCP, on the expression of ethylene biosynthetic and perception genes was also analyzed. Cold
storage markedly stimulated the expression of ethylene biosynthetic genes; ACC synthase 1 and 2 (ACS1 and ACS2) and ACC oxidase (ACO) in the peel of both cultivars. Expression of ACS1, ACS2 and ACO were overstimulated in the peel of 1-MCP-treated fruit, indicating a negative feedback control of ethylene on the process. Expression of three members of the ETR gene family was also affected by low temperature, but expression of ETR3 gene experienced the major induction by cold stress in the peel of fruit of both cultivars. Pre-treatment with 1-MCP did not show a clear and consistent effect on the expression of the ETR genes. These results illustrate the complex regulation of the different members of ethylene biosynthetic, signaling and response pathway by cold stress in the peel of grapefruits. MenosABSTRACT.
