Barley landraces; Genetic diversity; Hordeum vulgare; PIC; SSR markers

We analyzed the genetic diversity of 115 barley germplasms, including 112 landraces and three new barley cultivars grown in the Shanghai region, using a set of 11 SSR markers. Sixty-six alleles were observed at the 11 SSR loci, ranged from three to ten, with a mean of six alleles per locus. The polymorphism information content ranged from 0.568 to 0.853, with a mean of 0.732, indicating ... more

Yield losses caused by lodging in barley can be partially controlled by reducing plant height. In order to understand dwarfing mechanisms and efficiently use new dwarf germplasms for a breeding program, it is important to identify QTL of plant height components. QTL analysis was performed for seven plant height component traits using a DH population of 122 lines derived from the cross of ... more

Barley; Drought stress; Gene cloning; Gene expression; HbSINA4; Hordeum vulgare

Hulless barley is an important crop cereal in Tibetan, China. Drought is a major abiotic stress in barley production. In this study, we cloned the drought-related HbSINA4 gene from the variety ‘Himalaya 10’ and analyzed its expression patterns under different drought and rehydration conditions. The cDNA of HbSINA4 was 1052 bp long, including an open reading frame of 771 ... more

Drought-responsive genes; Hordeum vulgare; Neighbor-joining tree

The abscisic acid (ABA) signaling pathway is known as one of the most important signaling pathways in plants and is mediated by multiple regulators. The genes SnRK2, PYR/PYL/RCAR, and ABF are relevant to both ABA-dependent and -independent signaling pathways. To elucidate the profile of these genes from ... more

Cell-free DNA; Maternal plasma; Temperature; yield

In this study, we attempted to explore the factors affecting the yield of cell-free fetal DNA (cffDNA) obtained from maternal blood samples, including the use of different types of collection tubes, the interval between sample processing, and sample shipping under extreme weather conditions. Blood samples were drawn into K3EDTA tubes and cell-stabilizing tubes (Streck blood collection ... more

Fragaria x ananassa; Genotype x environment interaction; yield

Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, and helps provide specific ... more

Nitrogen via solid urea is easily lost by volatilization and leaching. This element, due to its easy absorption and translocation, shows the possibility of foliar supply. Knowledge of the dynamics of urea dissolved in water and foliar spraying on oats can improve use efficiency. The bjective of this study was to assess the urea dlution time under non-linearity of ... more

Two studies were undertaken with the aim of assessing the phenotypic stability and progression of ASR severity in soybean cultivars within a tropical altitude climate. In the first study, six commercial soybean cultivars containing the INOX® and a multiline cultivar were evaluated in 24 environments during the 2017/18 and 2018/19 growing seasons, assessing yield ... more
