Improves Defense Against by Regulating ROS and RNS Metabolism, Redox Balance, and Energy Flow in Cucumber Roots.

Plant survival in the terrestrial ecosystem is influenced by both beneficial and harmful microbes. spp. are a group of filamentous fungi that promote plant growth and resistance to harmful microbes.

[Establishment of the detection method for two causative genes of cattle arachnomelia syndrome].

Arachnomelia syndrome (AS) is a recessive inherited disease in cattle. Although the arachnomelia phenotypes are virtually identical in Brown Swiss and Simmental cattle, the causative mutation are different, which are a 1 bp insertion c.363-364insG in the sulfite oxidase (SUOX) gene and a 2 bp deletion c.

Cultural studies coupled with DNA based sequence analyses and its implication on pigmentation as a phylogenetic marker in Pestalotiopsis taxonomy.

Previous phylogenetic studies based on DNA sequence data have partially resolved taxonomic relationships among Pestalotiopsis species. There are still some morphological characters whose phylogenetic significance have not been assessed properly due to limited taxon sampling, in particular the degree of pigmentation of median cells. In this study, the stability of pigmentation of median cells of conidia in Pestalotiopsis species was evaluated in subculture, and a molecular phylogenetic analysis was conducted on 45 strains belonging to 26 species in order to reappraise the pigmentation of median cells for its significance in the taxonomy of Pestalotiopsis.

[Research advances in endophytic fungi of mangrove].

Mangrove, a kind of special host plants, is a resource of abundant endophytic fungi. More than 200 species of endophytic fungi are isolated and identified from mangrove, being the second largest community of marine fungi. The reported endophytic fungi of mangrove are mainly Alternaria, Aspergillus, Cladosporium, Colletotrichum, Fusarium, Paecilomyces, Penicillium, Pestalotiopsis, Phoma, Phomopsis, Phyllosticta and Trichoderma.

[Effects of salt stress on the growth and the nitrate reductase activity in Thellungiella halophila].

The results showed that when Thellungiella halophila was treated with NaCl, the fresh and dry weight, the water content, the succulency of whole plant and the root/shoot ratio were decreased (Figs. 2-4, 7); the organic matter content in roots was increased and the inorganic matter content in roots was decreased, while those in shoots changed in the opposite direction (Fig. 6); osmotic adjustment ability, the Na+ content, the root activity were increased (Figs.

[Osmotica accumulation and its role in osmotic adjustment in Thellungiella halophila under salt stress].

Thellungiella halophila was treated with different concentrations of NaCl (0, 50, 100, 200, 300 and 400 mmol/L). Water content, osmotic potential, various organic and inorganic osmotica contents in the leaves and roots were determined and the calculated osmotic potential (COP) of osmotica in the osmotic adjustment was calculated (Figs.1-10 and Table 1).
