Flooding tolerance in Rice: adaptive mechanism and marker-assisted selection breeding approaches.

Natural and man-made ecosystems worldwide are subjected to flooding, which is a form of environmental stress. Genetic variability in the plant response to flooding involves variations in metabolism, architecture, and elongation development that are related with a low oxygen escape strategy and an opposing quiescence scheme that enables prolonged submergence endurance. Flooding is typically associated with a decrease in O in the cells, which is especially severe when photosynthesis is absent or limited, leading to significant annual yield losses globally.

The Effects of Annealing Temperatures on Composition and Strain in SiGe Obtained by Melting Growth of Electrodeposited Ge on Si (100).

The effects of annealing temperatures on composition and strain in SiGe, obtained by rapid melting growth of electrodeposited Ge on Si (100) substrate were investigated. Here, a rapid melting process was performed at temperatures of 1000, 1050 and 1100 °C for 1 s. All annealed samples show single crystalline structure in (100) orientation.

Crystallization of Electrodeposited Germanium Thin Film on Silicon (100).

We report the crystallization of electrodeposited germanium (Ge) thin films on n-silicon (Si) (100) by rapid melting process. The electrodeposition was carried out in germanium (IV) chloride: propylene glycol (GeCl₄:C₃H₈O₂) electrolyte with constant current of 50 mA for 30 min. The measured Raman spectra and electron backscattering diffraction (EBSD) images show that the as-deposited Ge thin film was amorphous.

Elimination and detection of viruses in meristem-derived plantlets of sweetpotato as a low-cost option toward commercialization.

Viral diseases affecting sweetpotato are the most devastating and cause up to 98 % yield loss. In this paper, we report, meristem culture, graft transmission and virus indexing for management of viral pathogens in seven elite sweetpotato cultivars. Plantlets were developed in vitro from the apical meristematic dome with one to two leaf primordia.
