- Abstract:
- ... rhm1 is a major recessive disease resistance locus for Southern corn leaf blight (SCLB). To further narrow down its genetic position, F2 population and BC1F1 population derived from the cross between resistant (H95rhm) and susceptible parents (H95) of maize (Zea mays) were constructed. Using newly developed markers, rhm1 was initially delimited within an interval of 2.5 Mb, and then finally mapped ...

- Abstract:
- ... The enigma of the transmissible disease of Helminthosporium victoriae has almost been resolved. Diseased isolates are doubly infected with two distinct viruses, the victorivirus Helminthosporium victoriae virus 190S and the chrysovirus HvV145S. Mixed infection, however, is not required for disease development. DNA transformation experiments and transfection assays using purified HvV190S virions st ...

- Abstract:
- ... The study describes a novel diagnostic protocol based on a loop-mediated isothermal DNA amplification (LAMP) for identification of wheat grains infection by Tilletia laevis, Tilletia caries (common bunt) and Tilletia controversa (draft bunt). The presented data showed that the LAMP analysis is a simple, specific and rapid method that could be used for detection of Tilletia spp. in contaminated gra ...

- Abstract:
- ... Acorus calamus (sweet flag), family Acoraceae, is a perennial herb distributed in India, Europe, East Asia, and North America. It is cultivated globally for β-asarone-rich essential oil that has carminative, antispasmodic, insecticidal, larvicidal, and antihelminthic properties (Devi and Ganjewala 2009). In July 2016, brown spots 2 to 3 mm in diameter were observed on both sides of leaves in exper ...

- Abstract:
- ... Chrysalidocarpus lutescens (areca palm) is a tropical ornamental plant grown in parks and houses worldwide. In August 2018, leaf spot symptoms were observed on C. lutescens plants in Fujian Agriculture and Forestry University (26°5′16″N, 119°14′6″E), Fuzhou, China. Approximately, 60% of C. lutescens plants were infected, with initial symptoms characterized as small dark brown to black spots of 1.5 ...

- Abstract:
- ... Browntop millet (Brachiaria ramosa [L.] Stapf), which is native to India, was recently introduced as one of the small millet crops. In September 2018, leaf blight symptoms were observed on cultivar Dundu Korale on the adaxial side of the leaves in a field at Bangalore, India (13.0784°N, 77.5793°E). Initial lesions were brown with a small yellow halo that ranged from 1 to 5 mm and eventually enlarg ...
