Quinoa (Chenopodium quinoa Willd.) has been proposed as a hardy alternative to traditional grain crops in areas with warm-to-hot climates that are likely to experience increased drought and salt stress in the future. We characterised the diffusive and metabolic limitations to photosynthesis in quinoa exposed to drought and salt stress in isolation and combination. Drought-induced pronounced sto...
Increasingly, photosynthetic electron transport rate is being calculated from chlorophyll fluorescence measurements. The fluorescence signal is a complex mixture of contributions from different depths within the mesophyll. One condition required for electron transport calculated from fluorescence to represent the rate accurately is that the ratio of photosynthetic capacity to light absorbed be ...
Transgenic antisense tobacco plants with a range of reductions in sedoheptulose-1,7-bisphosphatase (SBPase) activity were used to investigate the role of photosynthesis in stomatal opening responses. High resolution chlorophyll a fluorescence imaging showed that the quantum efficiency of photosystem II electron transport (F(q)(')/F(m)(')) was decreased similarly in both guard and mesophyll cell...
Increases in rates of individual leaf photosynthesis (P(n)) are critical for future increases in yields of rice plants. Although many efforts have been made to improve rice P(n) with transgenic technology, the desired increases in P(n) have not yet been achieved. Two rice lines with extremely high values of P(n) were identified among the backcrossed inbred lines derived from the indica variety ...
The plants follow various strategies for adapting and mitigating climatic environmental stresses. This offers an opportunity to comprehend adaptation mitigation mechanisms under changing climate environment emerging from vehicular emissions. We deployed approach, i.e., physiological (Phy) biophysical (Bioph) functional traits (FTs) based approach understand plant response assessing potential of...
