An improved procedure for the mechanical isolation of chloroplasts of high degree of intactness (90-95%) and photosynthetic capacity (25-50 mmol of O2/s per mol of chlorophyll) is described. The combination of pea plants (Pisum sativum L.) as starting material and the high reproducibility of the procedure readily and cheaply yields reliable intact chloroplasts for photosynthetic studies.

The content of cytochrome (cyt) bf complex is the main rate-limiting factor that determines light- and CO2-saturated photosynthetic capacity. A study of the half-life of the cyt f content in leaves was conducted whereby Pisum sativum L. plants, grown in moderately high light (HL), were transferred to low light (LL). The cyt f content in fully-expanded leaves decreased steadily over the 2 weeks after the HL-to-LL transfer, whereas control leaves in HL retained their high contents. The difference between the time courses of HL-to-LL plants and control HL plants represents the time course of loss of cyt f content, with a half-life of 1.7 days, which is >3-fold shorter than that reported for tobacco leaves at constant growth irradiance using an RNA interference approach (Hojka et al. 2014). After transfer to LL (16 h photoperiod), pea plants were re-exposed to HL for 0, 1.5 h or 5 h during the otherwise LL photoperiod, but the cyt f content of fully-expanded leaves declined practically at the same rate regardless of whether HL was re-introduced for 0, 1.5 h or 5 h during each 16 h LL photoperiod. It appears that fully-expanded leaves, having matured under HL, were unable to increase their cyt f content when re-introduced to HL. These findings are relevant to any attempts to maintain a high photosynthetic capacity when the growth irradiance is temporarily decreased by shading or overcast weather.

Arundo Donax L

Arundo donax L. (giant reed) is a perennial rhizomatous grass and has been identified as an important non-food biomass crop with capacity for cultivation in marginal and degraded lands where water scarcity conditions frequently occur due to climate change. This review analyzes the effect of water stress on photosynthetic capacity and biomass production in multiple giant reed ecotypes grown in different regions around the world. Furthermore, this review will attempt to explain the reason for the high photosynthetic capacity of giant reed even under changing environmental conditions as well as indicate other morphological reasons that could contribute to maintaining this high photosynthetic rate. Finally, future research in favor of selecting ecotypes with drought tolerance is proposed.
