SLAF-seq Uncovers the Genetic Diversity and Adaptation of Chinese Elm (Ulmus parvifolia) in Eastern China [PDF]

Forests, 2020
The Chinese elm is an important tree ecologically; however, little is known about its genetic diversity and adaptation mechanisms. In this study, a total of 107 individuals collected from seven natural populations in eastern China were investigated by ...

Meteorological Influences on Respirable Fragment Release from Chinese Elm Pollen

Aerosol Science and Technology, 2006
Exposure to airborne pollen from certain plants can cause allergic disease, leading to acute respiratory symptoms. Whole pollen grains, 15–90 µm-sized particles, provoke the upper respiratory symptoms of rhinitis (hay fever), while smaller pollen fragments capable of depositing in the lower respiratory tract have been proposed as the trigger for asthma.

A new species of the elm powdery mildew species complex (Erysiphaceae) on Chinese elm (Ulmus parvifolia) in East Asia segregated from Erysiphe ulmi

Phytotaxa, 2020
Powdery mildews are common pathogens on wild elm trees as well as on planted ornamentals in Asia and Europe. The taxonomy of the powdery Erysiphe species on elms (Ulmus spp., Ulmaceae) is complicated by taxonomical changes and inconsistently labelled DNA

Identification of RAPD markers linked to a black leaf spot resistance gene in Chinese elm

Theoretical and Applied Genetics, 1995
Black leaf spot (Stegophora ulmea) is a common foliage disease on Chinese (Ulmus parvifolia) and Siberian elms (U. pumila), two species which have been widely used as sources of Dutch-elm disease-resistance genes for interspecific elm hybrids. A dominant gene controlling resistance to black leaf spot was identified in a population derived from self ...

Strength Properties of Chinese Elm

Journal of Forestry, 1942
Some 20 million Chinese elms have been planted by the Prairie States Forestry Project. It is out-numbered only by green ash and cottonwood. Prudence requires that we know something about the physical and mechanical properties of this widely planted ...

A New Method Combining KECA-LDA With ELM for Classification of Chinese Liquors Using Electronic Nose

IEEE Sensors Journal, 2016
We proposed a hybrid algorithm by combining kernel entropy component analysis (KECA) with linear discriminant analysis (LDA), namely, KECA-LDA for feature reduction in electronic-nose systems. It combined the advantages of KECA and LDA. Then, the data extracted by KECA-LDA were inputted to extreme learning machine (ELM) for classification.

Micropropagation and germplasm conservation of Central Park Splendor Chinese elm (Ulmus parvifolia Jacq. ‘A/Ross Central Park’) trees

Plant Cell Reports, 2007
Micropropagation offers opportunities to propagate, preserve and ship tree germplasm. It also reduces the risk of moving pathogens and insects with the germplasm due to built-in pathogen detection capabilities of aseptic cultures. For the past few decades, our laboratory has been involved in a project to preserve and restore a large, cold hardy, and ...
