In the cold regions of China, lignin-rich corn straw accumulates at high levels due to low temperatures. The application psychrotrophic lignin-degrading bacteria should be an effective means overcoming low-temperature limit for lignin degradation and promoting utilization straw. However, this is limited by lack suitable strains decomposition lignin; furthermore, metabolic mechanism unclear. Here, whole genome bacterium Arthrobacter sp. C2, isolated in our previous work, was sequenced....

Lanjingling) obtained Harbin, China (128.70°E, 44.87°N) showed postharvest rot symptoms after 15 d at 4°C, leading to whole rotting with gray fungal growth (Fig.1 A). Small (1-2 mm) segments infected tissue were from 20 randomly selected which surface sterilized 75% ethanol...

Lentinan (LNT) is a natural and functional polysaccharide isolated from Lentinus edodes fruiting bodies, which functions in stimulating the plant immune response, improving disease resistance regulating growth. This study explores use of LNT as growth regulator attractant cotton production. After treatment with LNT, content malondialdehyde (MDA) seeds decreased, whereas activities polyphenol oxidase (PPO), superoxide dismutase (SOD) peroxidase (POD) leaves increased significantly. also...

Blue honeysuckle (Lonicera caerulea L.) is a perennial plant of the Caprifoliaceae family and Lonicera genus, largest genus in kingdom. Between September 2021 2022, leaf spot disease was observed on ~20% blue honeysuckles 'Lanjingling' cultivar grown 3.33 ha field at Xiangyang base (126.96°E, 45.77°N) Northeast Agricultural University, Harbin (Heilongjiang Province, China). Leaf spots first presented black mildew centers, gradually covering large areas until it eventually fell off. Small 3-4...

Relatively few studies investigating plant diseases in blue honeysuckle (Lonicera caerulea L.) have been conducted China. In September 2021, a leaf spot disease was observed on approximately 10% of 'Lanjingling' leaves 0.02 ha field plantation Tiekuang Street (124.36°E, 40.12°N) Dandong City, Liaoning Province, The main symptom consisted spots with black mildew centers typically surrounded by yellow halos. Small pieces (3-4 mm) the infected were plated onto potato dextrose agar (PDA) medium...
