Proteins produced by the large and diverse chitinase gene family are involved in the hydrolyzation of glycosidic bonds in chitin, a polymer of N-acetylglucosamines. In flowering plants, class I chitinases are important pathogenesis-related proteins, functioning in the determent of herbivory and pathogen attack by acting on insect exoskeletons and fungal cell walls. Within the carnivorous plants...

Features in which Agdestis differs from Phytolaccaceae s. s. include presence of both libriform fibers and vasicentric tracheids (rather than one or the other); bands and strands of thin-walled apotracheal parenchyma (in addition to paratracheal scanty parenchyma}, and raylessness (also reported for Bougainvillea of Nyctaginaceae, a family close to Phytolaccaceae). Dimorphism in vessel diameter...

Reaumuria soongorica and sand rice (Agriophyllum squarrosum) belong to the clade of Caryophyllales and are widely distributed in the desert regions of north China. Both plants have evolved many specific traits and adaptation strategies to cope with recurring environmental threats. However, the genetic basis that underpins their unique traits and adaptation remains unknown. In this study, the tr...

Implications for adults' fitness through the foliage effects of five different host plants on larval survival and performance of the lappet moth, Streblote panda Hübner (Lepidoptera: Lasiocampidae), as well as their effect on species fitness were assayed. Larvae were reared under controlled laboratory conditions on excised foliage. Long-term developmental experiments were done using first insta...

From the perspective of sustainable agri-food production, farmers need to make best use natural resources. Biochar can be a solution adopt more way farming. Despite its environmental and agronomic advantages, biochar has low plant nutrient value. This study evaluated effect co-application an inorganic or organic fertilizer on soil properties, growth content Swiss chard (Beta vulgaris L. var. cy...

BACKGROUND The cultivation of saffron is expanding through the southeast of Iran, and allergy to saffron pollen occurs in workers involved in processing this plant. We aimed to clone, sequence and express a major allergen involved in saffron pollen allergy, and to compare the recombinant with the natural allergen. METHODS The N-terminal amino acid sequence of Cro s 1, an allergen from saffron...

Genetic diversity and relationships of 11 species and cultivars belonging to different Angiosperms families were examined using sodium dodecyl sulfate seed protein markers. The protein was resolved into 36 bands (for soybean), 41 (for quinoa), 35 (for buckwheat), and 28 to 39 bands of Amaranth species, respectively. All species and cultivars can be distinguished from each other. Soybean, quinoa...
