Mesophyll conductance to CO2: current knowledge and future prospects.
There is now evidence that g(liq) and, in some cases, g(w), are the main determinants of g(m). Expand
Drought-inhibition of photosynthesis in C3 plants: stomatal and non-stomatal limitations revisited.
The analysis suggests that stomatal closure is the earliest response to drought and the dominant limitation to photosynthesis at mild to moderate drought, however, in parallel, progressive down-regulation or inhibition of metabolic processes leads to decreased RuBP content, which becomes the dominant limit at severe drought, and thereby inhibits photosynthetic CO2 assimilation.

Regulation of photosynthesis of C3 plants in response to progressive drought: stomatal conductance as a reference parameter.
A study with six Mediterranean shrubs revealed that, in spite of some marked interspecific differences, all followed the same pattern of dependence of photosynthetic processes on stomatal conductance, and this pattern was quite similar to that of grapevines. Expand
Keeping a positive carbon balance under adverse conditions: responses of photosynthesis and respiration to water stress
Drought and salinity (i.e. soil water stress) are the main environmental factors limiting photosynthesis and respiration and, consequently, plant growth. This review summarizes the current status ofExpand
Rapid variations of mesophyll conductance in response to changes in CO2 concentration around leaves.
Transgenic tobacco plants differing in the amounts of aquaporin NtAQP1 showed different slopes of the gm-Ci response, suggesting a possible role for aquaporins in mediating CO2 responsiveness of gm, and the importance of these findings is discussed in terms of their effects on parameterization of AN-CI curves.

Effects of drought on photosynthesis in grapevines under field conditions: an evaluation of stomatal and mesophyll limitations.
The apparent carboxylation efficiency and the compensation point for CO2 remained unchanged under severe drought when analysed on a Cc, rather than a Ci, basis, suggesting that previously reported metabolic impairment was probably due to decreased gmes. Expand
Mesophyll conductance to CO 2 : current knowledge and future prospects
A revision of current knowledge on mesophyll conductance is presented, and a historical perspective is given, highlighting the founding works and methods, followed by a re-examination of the range of variation of gm among plant species and functional groups. Expand
Drought-induced changes in development and function of grapevine (Vitis spp.) organs and in their hydraulic and non-hydraulic interactions at the whole-plant level: a physiological and molecular
Features observed in different organs show that grapevine fits well as a complex model plant for molecular and physiological studies on plant drought avoidance/tolerance. Expand
Physiological tools for irrigation scheduling in grapevine (Vitis vinifera L.): An open gate to improve water-use efficiency?
Current knowledge on grapevine responses to water stress is summarised, and the usefulness of different physiological parameters is discussed, and current knowledge on their applicability for water stress detection and irrigation management in grapevines is reviewed. Expand
Photosynthetic limitations in response to water stress and recovery in Mediterranean plants with different growth forms.
A general pattern of photosynthetic response to water stress among C(3) plants when stomatal conductance (g(s)) is used as a reference parameter is confirmed, and recovery of severely stressed plants after rewatering showed a dominant role of MC(L), irrespective of the degree of photosynthesis recovery.
