Sunflower (Helianthus annuus L.), which is widely grown globally for its high-quality edible oil, reasonably salt and drought tolerant but it susceptible to waterlogging. In the saline coastal zone of Ganges delta, sunflower often exposed sudden heavy rainfall during early growth plant tolerance such events not known. Hence, we evaluated effect short-term soil inundation (referred as waterloggi...

Like struggling swimmers trying to keep their heads above water, rosette plants lift up their leaves when faced with flooding. Instead of flailing arms and legs, plants use hyponastic petiole growth to improve their chances of keeping leaves in contact with the air. During this hyponastic growth, cells on the abaxial side of the petiole elongate more than those on the adaxial side, changing the...

Phytophthora cinnamomi is a major pathogen of Eucalyptus marginata (jarrah) in Western Australia (23). It can kill trees of all ages through infection of roots (10,27) or by girdling the trunks of 1to 7year-old trees in situations were the collar is ponded (12,19). Field observations have indicated that periods of waterlogging (low oxygen) can result in the rapid death of trees from P. cinnamom...

Waterlogging is a major abiotic stress that limits the growth of plants. The crucial role of Ca(2+) as a second messenger in response to abiotic and biotic stimuli has been widely recognized in plants. However, the physiological and molecular mechanisms of Ca(2+) distribution within specific cell types in different root zones under hypoxia is poorly understood. In this work, whole-plant physiol...

The objective of this investigation was to study the effects of nitrogen on tolerance to water-stress in cotton (Gossypium hirsutum L.) seedlings. Growth chamber studies with pots of washed sand were carried out in Fayetteville, USA, and Nanjing, Chinawith three water conditions (well-watered, drought-stressed, and waterlogging), and three nitrogen rates, low nitrogen (16 mM, approximately 224 ...

The formation of aerenchyma in adventitious roots is one the most crucial adaptive traits for waterlogging tolerance plants. Pasture grasses, like other crops, can be affected by waterlogging, and there scope to improve through breeding. In this study, two summer-active cocksfoot (Dactylis glomerata L.) cultivars, Lazuly Porto, tall fescue (Lolium arundinaceum Schreb., syn. Festuca arundinacea ...

salix integra thunb. is a shrub distributed in china along the huai river riparian zone, and plays an important role in water and soil conservation. s. integra shrub land is easily submerged during july to october due to the flooding of huai river. in order to characterize the physiological mechanisms of waterlogging tolerance of s. integra and to help rationally select waterlogging-tolerant sp...

In the monsoon season, sudden flood events occur frequently in urban areas, which hamper social and economic activities may threaten infrastructure lives. The use of an efficient large-scale waterlogging sensing information system can provide valuable near real-time disaster to facilitate management enhance awareness general public alleviate losses during after disasters. Therefore, this study,...
