Barley; Chromosome 2H; EST-PCR marker; Wheat

We developed EST-PCR markers specific to barley chromosome 2H, for the purpose of effectively tracing alien chromosomes or chromosome parts in the wheat genetic background. The target alien chromosome 2H confers high resistance to pre-harvest sprouting, which is a worldwide natural disaster in wheat. A total of 120 primer pairs were selected by combining the wheat group 2 chromosomes of ... more

Barley; Genetic relationship; Hordeum vulgare L.; Lodging; Lodging components; Unconditional and conditional QTL analysis

Lodging (LD) is a major constraint limiting the yield and forage quality of barley. Detailed analyses of LD component (LDC) traits were conducted using 246 F2 plants generated from a cross between cultivars ZQ320 and 1277. Genetic relationships between LD and LDC were evaluated by unconditional and conditional quantitative trait locus (QTL) mapping with 117 simple sequence ... more

Barley; Mature embryo; TAIL-PCR

Mature embryos in tissue cultures are advantageous because of their abundance and rapid germination, which reduces genomic instability problems. In this study, 2-day-old isolated mature barley embryos were infected with 2 Agrobacterium hypervirulent strains (AGL1 and EHA105), followed by a 3-day period of co-cultivation in the presence of L-cystein amino acid. Chimeric expression ... more

Agronomic character; Hordeum vulgare; Lodging resistance; yield

Germplasm collections represent an important genetic source for crop improvements. In this study, 220 accessions of hulless barley were collected worldwide and their genetic diversity was investigated. Sixteen agronomic traits, including yield and yield components, grain morphology, leaf size, plant height, and lodging resistance, were assessed under field conditions. All studied traits ... 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

Cold stress; DREB transcription factor; Drought stress; Moso bamboo; Salt treatment

Moso bamboo is a large woody bamboo with the highest ecological, economic, and cultural value among all bamboos in Asia. However, environmental stress influences its growth and development and limits its geographic distribution. Therefore, improving its resistance to environmental stress is extremely important. Dehydration responsive element binding (DREB) transcription factors perform an ... more

Drought stress; Larix olgensis families; Proteomics

The conifer Larix olgensis has been analyzed to delineate physiological and proteomic changes that occur under drought stress. Studies of the deleterious effects of drought in the larch families have mainly focused on photosynthesis. In the present study, when the intensity of drought was increased, plant height was inhibited as both POD and MDA levels increased, which indicates ... more

Agrobacterium tumefaciens; Drought stress; Gene transformation; Oryza officinalis; Wild rice

Oryza officinalis has proven to be a natural gene reservoir for the improvement of domesticated rice as it carries many desirable traits; however, the transfer of elite genes to cultivated rice by conventional hybridization has been a challenge for rice breeders. In this study, the conserved sequence of plant stress-related NAC transcription factors was selected as a ... more

Gene expression; Hypoxia; Muscle; Pig

Hypoxia influences many physiological processes, such as respiration, cardiovascular, neurophysiology, and digestion. Skeletal muscle is an important motor organ, which relies on oxygen of oxidation; however, the study of hypoxia in skeletal muscle is lacking. In order to understand the effect of hypoxia on skeletal muscle, we determined the expression level of four hypoxia-related genes ( ... more

Gene expression; Hyperplasia and hypertrophy; Megalobrama amblycephala; Morphological analysis; Muscle fiber

Skeletal muscle growth is regulated by both positive and negative factors, such as myogenic regulatory factors (MRFs) and myostatin (MSTN), and involves both hyperplasia and hypertrophy. In the present study, morphological changes during muscle development in Megalobrama amblycephala were characterized and gene expression levels were measured by quantitative real-time polymerase chain ... more
