Due to rainfall, closed weeding of paddy fields and other reasons, submergence stress often occurs during the germination emergence stages direct-seeded rice (Oryza sativa L.), which leads intensified anaerobic respiration, accelerated consumption stored nutrients, difficulty in seeds, uneven seedlings varying yields. Recent advances understanding phytohormone interaction regulation signaling p...

Climate change and the consequent increase in incidence of drought flood will remain a major threat to smallholders. Hence, it is crucial adopt an appropriate adaptation strategy overcome this farmers’ income. Because seed primary input, adoption stress-tolerant rice varieties potential mitigation combat climate risks. In context, present study carried out among paddy farmers flood-prone region...

Submergence stress due to flash floods reduces rice yield drastically in sensitive varieties. Maudamani is a high yielding popular variety but highly susceptible submergence stress. The selection of progenies carrying Sub1 and GW5 (wide-grain) enhanced the tolerance grain theMaudamani by following marker-assisted backcross breeding method. Foreground screening detected 14 BC1F1, 17 BC2F1, 12 BC...

Rotating biological contactors (RBCs) constitute a very unique and superior alternative for biodegradable matter and nitrogen removal on account of their feasibility, simplicity of design and operation, low land area requirement, low energy consumption, low operating and maintenance cost and treatment efficiency. The present review of RBCs focus on parameters that affect performance like rotati...

Aspects of the paleogeography, stratigraphy, and glacial history of Beringia have been greatly revised over the past 15}20 yr. Access to North East Russia, in particular, has provided the opportunity to evaluate the Beringia landscape as a contiguous subcontinent during the Quaternary. For the "rst time, new research has made clearer the connection between tectonic forces and the submergence of...

In preliterate contexts, diverse knowledge was accumulated, processed and communicated orally. Recent research demonstrates that observations of memorable events were transferred in this way for thousands years sometimes. Much information eventually written down to reach literate audiences, which commonly judge such ‘myths legends’ be cultural inventions rather than ancient memories. This study...

Ronald’s laboratory has engineered rice for resistance to disease and tolerance to flooding, which seriously threaten rice crops in Asia and Africa. Ronald led the isolation of the rice XA21 immune receptor, the bacterial Ax21 quorum sensing factor and the rice Sub1A submergence tolerance transcription factor. In 1996, she established the Genetic Resources Recognition fund, a mechanism to recog...

Deep sea exploration and exploitation are of an increasingly interest to human beings in the 21 century. Manned and unmanned deep submergence vehicles are necessary means for deep sea explorations. In order to fulfill the requirements of deep sea explorations of COMRA (China Ocean Mineral Resources R&D Association), a deep manned submersible is developed in China and it is now named “Harmony”. ...
