Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) was used to systematically investigate the impact of solar ultraviolet-B (UV-B) radiation on the soybean leaf proteome. In order to investigate the protective role of flavonoids against UV-B, two isolines of the Clark cultivar (the standard line with moderate levels of flavonoids and the magenta line with reduced flavonoids) were gro...

Leaf spots and rust are the most destructive diseases of peanut in Tropical Africa, but it has shown that Akanthomyceslecanii isknown ashyperparasiteof rustandleaf fungi. Previous studies have investigated on use conidia A.lecaniiin biocontrol these diseases. However, influenced by temperature relative humidity, which could result low efficiency agents natural conditions. The secondary metaboli...

Two Castanea plant species, C. henryi and mollissima, are cultivated in China to produce chestnut crops. Leaf spot diseases commonly occur plantations, however, little is known about the fungal species associated with leaf spots. In this study, samples of mollissima were collected from Beijing, Guizhou, Hunan, Sichuan Yunnan Provinces, leaf-inhabiting fungi identified based on morphology phylog...

since 1895 cardamom has been cultivated in the cardamom hills of western ghats, india, which form a part of global biodiversity hot spots. these tropical forests in the last couple of decades have been subjected for severe periodical shade lopping and selective felling for maximizing cardamom production. photosynthesis, transpiration, leaf temperature and leaf relative humidity was studied in r...

this paper deals with the study of a leaf spot disease observed on aloe vera leaves in various nurseries and botanical gardens during the routine surveys of two consecutive years of 2010 and 2011. the symptoms appeared in the form of circular to oval, brown to black, sunken spots on abaxial surface of leaves. the disease was observed only in january to february during the survey. colonieson pda...

Received Jan 1, 2018 Revised Mar 15, 2018 Accepted Mar 29, 2018 Disease in palm oil sector is one of the major concerns because it affects the production and economy losses to Malaysia. Diseases appear as spots on the leaf and if not treated on time, cause the growth of the palm oil tree. This work presents the use of digital image processing technique for classification oil palm leaf disease s...

Anatomical studies in the leaflet globoid galls of Caryocar brasiliense, the “pequi”, aimed to answer how oviposition and the feeding behavior of the galling herbivores altered the morphogenetical patterns of the host plant. C. brasiliense globoid gall was (1.28 ± 0.20) mm × (0.90 ± 0.25) mm, with hairy surface; it is sessile and projected to the abaxial surface. Young galls were red while the ...

The spatial patterns for temperature distribution on crape myrtle leaves infested with sooty mold were investigated using a digital infrared thermal imaging camera. The mean temperatures of the control and sooty regions were 26.98°C and 28.44°C, respectively. In the thermal images, the sooty regions appeared as distinct spots, indicating that the temperatures in these areas were higher than tho...
