“…Thus, all the photochemical reactions affect fluorescence emission. For example, impaired electron transport results in higher fluorescence emission (Guo and Tan, 2015). Several studies have reported diminished F v /F m (Figure 2) when sugarcane plants experienced water stress (Silva et al, 2007, 2013; Silva M. D. A. et al, 2014; Da Graça et al, 2010).…”

Sugarcane is a unique crop with the ability to accumulate high levels of sugar and is a commercially viable source of biomass for bioelectricity and second-generation bioethanol. Water deficit is the single largest abiotic stress affecting sugarcane productivity and the development of water use efficient and drought tolerant cultivars is an imperative for all major sugarcane producing countries. This review summarizes the physiological and molecular studies on water deficit stress in sugarcane, with the aim to help formulate more effective research strategies for advancing our knowledge on genes and mechanisms underpinning plant response to water stress. We also overview transgenic studies in sugarcane, with an emphasis on the potential strategies to develop superior sugarcane varieties that improve crop productivity in drought-prone environments.

“…It is known that C. mariscus thrives in water with depths 5 to 25 cm in marshes of Greece (Theocharopoulos et al 2006) and in a lake in North-Eastern Poland C. mariscus was submerged to a depth of 10 to 30 cm (Namura-Ochalska 2005). Chlorophyll a fluorescence parameter F v /F m has been used as a physiological marker to estimate plant response to environmental factors like waterlogging or flooding, drought, and temperature, but the results are contradictory and species-specific (Guo, Tan 2015) as well as experimental design-specific. In field experiments with Typha domingensis Pers., which grows together with Cladium mariscus subsp.…”

Effective conservation of priority habitat 7210* Calcareous fens with Cladium mariscus and species of the Caricion davallianae depends on complete knowledge of the biology of Cladium mariscus. This study was aimed to determine effect of temperature and habitat water level on growth, development and physiological status of generative shoots of C. mariscus. Maximum quantum yield of photosystem II photochemistry dynamics during both seasons was similar; but in summer 2016 the values were significantly higher than in 2015. Difference in height of generative shoots was not found between years. Average number of generative shoots indicated a significant difference between years. Immediate effect of temperature or habitat water level changes on generative shoot growth were not observed. However, two-season measurements of maximum quantum yield of photosystem II photochemistry showed that C. mariscus is welladapted to high habitat water level and might be sensitive to habitat water level fluctuations, when the water level falls below 5 cm. On the north-eastern limit of the distribution range the number of generative shoots of C. mariscus in the next growing season is affected by previous autumn drought and temperature below 0 °C as well.

“…However, Chl fluorescence parameters measured in vivo appear to be largely insensitive to mild water-deficit stress (e.g. Matoušková et al 1999;Proctor et al 2007;Erismann et al 2008;Guo and Tan 2015). These parameters reflect particularly primary photosynthetic processes in thylakoid membranes that are relatively unaffected during mild water-deficit stress (e.g.…”

Chloroplast avoidance movement as a sensitive indicator of relative water content during leaf desiccation in the dark

In the context of global climate change, drought is one of the major stress factors with negative effect on photosynthesis and plant productivity. Currently, chlorophyll fluorescence parameters are widely used as indicators of plant stress, mainly owing to the rapid, non-destructive and simple measurements this technique allows. However, these parameters have been shown to have limited sensitivity for the monitoring of water deficit as leaf desiccation has relatively small effect on photosystem II photochemistry. In this study, we found that blue light-induced increase in leaf transmittance reflecting chloroplast avoidance movement was much more sensitive to a decrease in relative water content (RWC) than chlorophyll fluorescence parameters in dark-desiccating leaves of tobacco (Nicotiana tabacum L.) and barley (Hordeum vulgare L.). Whereas the inhibition of chloroplast avoidance movement was detectable in leaves even with a small RWC decrease, the chlorophyll fluorescence parameters (F V/F M, V J, Ф PSII, NPQ) changed markedly only when RWC dropped below 70 %. For this reason, we propose light-induced chloroplast avoidance movement as a sensitive indicator of the decrease in leaf RWC. As our measurement of chloroplast movement using collimated transmittance is simple and non-destructive, it may be more suitable in some cases for the detection of plant stresses including water deficit than the conventionally used chlorophyll fluorescence methods.
