Three Hordeum spontaneum-derived resistances (referred to as 145L2, 41T1 and 40Y5) have demonstrated long-term effectiveness against barley scald, caused by Rhynchosporium commune, in western Canada. Genetic mapping of these resistances in three populations, and the use of five barley genome assemblies, revealed they co-located to a narrowly defined 0.58-1.

- Barley loose smut is largely controlled by a specific gene, but certain inoculation methods can lead to poor seed quality and germination issues, especially in carrier and susceptible genotypes.
- Research compared a carrier strain (TR11698) and a susceptible strain (CDC Austenson), finding that lower inoculum concentrations improved seed traits and increased infection in the susceptible strain, while the carrier showed no infection but still had low germination rates.
- The study suggests that lowering inoculum levels can enhance seed appearance and germination in susceptible plants, while the carrier's seedling issues indicate a resistance mechanism, with increased abscisic acid levels potentially aiding in pathogen survival.

Since Fujita first described uvulopalatopharyngoplasty(UPPP)in 1981,UPPP and its modified procedures have been widely used to treat obstructive sleep apnea and hyponea syndrome(OSAHS).However,despite of its wide application,the success rates was uncertain,ranging from 20% to 80%,with patients of varing Friedman stages.It is well known that the principle of UPPP is to remove the redundant tissue of palate,elongated uvula and hypertrophic tonsils in order to widen the anteroposterior space at the level of palate.

Interaction between the coiled-coil domain of rice blast resistance protein Pi36 and methyl-jasmonate (MeJA) was studied by fluorescence and UV-vis spectroscopic techniques. The quenching mechanism of fluorescence of MeJA by this domain was discussed to be a static quenching procedure. Fluorescence quenching was explored to measure the number of binding sites n and apparent binding constants K.

We previously demonstrated the feasibility of p53 pathway restoration in p53-deficient tumor cell populations using small molecules including ellipticine or its derivatives. We now establish a single cell p53-regulated green fluorescent protein (EGFP)-reporter system in human DLD1 colon tumor cells expressing mutant p53 protein.

- In the post-genomic era, efficient and cost-effective systems for eukaryotic protein expression, like the baculovirus system, are increasingly important.
- A new method using MAGIC allows for the quick and high-efficiency creation of recombinant BmBacmid vectors in silkworms, achieving a 99.8% success rate in producing positive recombinants.
- This research enabled the high-level expression of various genes in silkworm larvae and proposed the potential to create a high-quality baculovirus cDNA library through plasmid transfer.
