Drought is a major abiotic stress that affects plant growth, development and productivity. Pear is one of the most important deciduous fruit trees in the world, but the mechanisms of drought tolerance in this plant are still unclear. To better understand the molecular basis regarding drought stress response, RNA-seq was performed on samples collected before and after dehydration in Pyrus betula...

the composition of the essential oils of nepeta crispa willd. and n. menthoides boiss. and buhse (lamiaceae) was investigated by means of gas chromatography (gc) and gc- mass spectrometery (ms). 1, 8-cineole was the most abundant component in oils: nepeta crispa (71%) and n. menthoides (41.1%). in the oil of n. crispa, b-pinene (5%) and d-terpineol (4.1%) were found to be the major constituents...

Pyrus calleryana was intentionally introduced to North America from east Asia in the early 1900s as rootstock for edible pear tree, communis. It identified an ideal decorative, agricultural, and horticultural tree because of its small stature, spring flowering, fire blight resistance inoffensive fruits. P. escaped cultivation is now considered invasive species, typically found on roadsides, pra...
