An updated overview of the physiological and molecular responses of rice to anoxia

Abstract

The promoters have variable elements compatible to other stressors 7. Physiological attribution of ethylene in rice to endure submergence stress 8. Signaling paths depend on other metabolites paraphernalia under anoxia 9. Anoxia compromises with energy turnover and executed in adoption by rice 10. Signaling paths of ethylene perception are diverse with different factors 11. Adoptive strategies in sugar and nitrogen metabolism under anoxia 12. Conclusions 13. Author contributions 14.

GWAS combined with transcriptome and metabolome to excavate key candidate genes for rice anaerobic germination

“…Likewise, the degradation of BCAAs provides energy for the early stages of Arabidopsis seed germination (Gipson et al 2017). Sugar metabolism is important for plant adaptation to anaerobic environments (Adak and Saha 2021). Plants respond to hypoxic stress by switching from oxidative respiration to fermentative glycolysis to generate metabolic energy, which enables them to survive hypoxic stress (Tadege et al 1999).…”

Effects of Drought and Flooding on Phytohormones and Abscisic Acid Gene Expression in Kiwifruit

“…Global warming is predicted to increase the frequency and intensity of extreme weather events such as drought and flooding. Detrimental environmental conditions can cause reductions in plant growth, affecting yield quality and quantity, and can result in significant crop losses [1][2][3][4][5][6]. Water stress, caused by drought and waterlogging, is the most significant constraint to crop production worldwide today [2,4,6] and research to interrogate the associated stress-response mechanisms is essential to facilitate the development of climate resilient varieties [2][3][4].…”

“…Flooding can cause waterlogging where the roots are saturated and/or submergence, where parts of the plant above ground are partially or completely covered with water [1,6].…”

“…Waterlogging aids pathogen infection, reduces oxygen availability and restricts gas exchange in submerged tissues causing an accumulation of toxic end-products [1]. Submergence can also increase pathogen infection, osmotic and salt stress, and reduces transpiration, nutrient uptake and transport leading to energy-starved tissues.…”

“…Submergence can also increase pathogen infection, osmotic and salt stress, and reduces transpiration, nutrient uptake and transport leading to energy-starved tissues. Prolonged submergence, however, results in the death of most terrestrial plants [1].…”
