Nature communications.Nat Commun.2015 Apr 10;6:6659. doi: 10.1038/ncomms7659.
Gluconeogenesis is a fundamental metabolic process that allows organisms to make sugars from non-carbohydrate stores such as lipids and protein. In eukaryotes only one gluconeogenic route has been described from organic acid intermediates and this relies on the enzyme phosphoenolpyruvate carboxykina

Efficient use of energy in anoxia-tolerant plants with focus on germinating rice seedlings.

Atwell BJ1, Greenway H, Colmer TD.
The New phytologist.New Phytol.2015 Apr;206(1):36-56. doi: 10.1111/nph.13173. Epub 2014 Dec 4.
Anoxia tolerance in plants is distinguished by direction of the sparse supply of energy to processes crucial to cell maintenance and sometimes to growth, as in rice seedlings. In anoxic rice coleoptiles energy is used to synthesise proteins, take up K(+) , synthesise cell walls and lipids, and in ce

Reduction of pyruvate orthophosphate dikinase activity is associated with high temperature-induced chalkiness in rice grains.

Wang ZM1, Li HX1, Liu XF1, He Y1, Zeng HL2.
Plant physiology and biochemistry : PPB / Société française de physiologie végétale.Plant Physiol Biochem.2015 Apr;89:76-84. doi: 10.1016/j.plaphy.2015.02.011. Epub 2015 Feb 20.
Global warming affects both rice (Oryza sativa) yields and grain quality. Rice chalkiness due to high temperature during grain filling would lower the grain quality. The biochemical and molecular mechanisms responsible for the increased occurrence of chalkiness under high temperature are not fully u
