“…In Senegal, a green barrier of C. equisetifolia was established on the northern Atlantic fringe between Dakar and Saint-Louis to stabilize sand dunes and protect the vegetable and fruit producing so-called “Niayes” area (Maheut and Dommergues, 1961; Mailly et al, 1994). C. equisetifolia is also appreciated for source of poles, firewood and charcoal (Diagne et al, 2013; Potgieter et al, 2014). Thus, this family of plants is of high importance for salinized land reclamation.…”

Symbiotic nitrogen-fixing associations between Casuarina trees and the actinobacteria Frankia are widely used in agroforestry in particular for salinized land reclamation. The aim of this study was to analyze the effects of salinity on the establishment of the actinorhizal symbiosis between C. glauca and two contrasting Frankia strains (salt sensitive; CcI3 vs. salt tolerant; CeD) and the role of these isolates in the salt tolerance of C. glauca and C. equisetifolia plants. We show that the number of root nodules decreased with increasing salinity levels in both plants inoculated with CcI3 and CeD. Nodule formation did not occur in seedlings inoculated with CcI3 and CeD, at NaCl concentrations above 100 and 200 mM, respectively. Salinity also affected the early deformation of plant root hairs and reduced their number and size. In addition, expression of symbiotic marker Cg12 gene, which codes for a subtilase, was reduced at 50 mM NaCl. These data suggest that the reduction of nodulation in C. glauca under salt stress is in part due to inhibition of early mechanisms of infection. We also show that prior inoculation of C. glauca and C. equisetifolia with Frankia strains CcI3 and CeD significantly improved plant height, dry biomass, chlorophyll and proline contents at all levels of salinity tested, depending on the Casuarina-Frankia association. There was no correlation between in vitro salt tolerance of Frankia strains and efficiency in planta under salt-stressed conditions. Our results strongly indicate that increased N nutrition, photosynthesis potential and proline accumulation are important factors responsible for salt tolerance of nodulated C. glauca and C. equisetifolia.

“…Second, the biology of its root-nodule symbiosis with Frankia has been studied extensively. Moreover, C. glauca shows an outstanding capacity to endure extreme environments, particularly saline conditions, as it tolerates seawater levels of salt and is commonly planted in areas with a shallow, saline water table (Diagne et al, 2013). Yet, as mentioned above, the subjacent adaptation mechanisms remain largely unknown.…”

“…Australian sheoaks have already been widely adopted for forestry, agroforestry and other purposes in east, south and south-east Asia, mostly in subhumid to humid contexts with lesser use in semi-arid to arid contexts [28] , and also in Africa including some relatively low rainfall contexts [60] . Most research and deployment has been with three Australian species (C. cunninghamiana, C. equisetifolia and C. glauca) and one Indonesian species (C. junghuhniana), being the larger more productive species.…”

Agroecosystems in water-limited contexts-Mediterranean, semi-arid and arid climatic zones-are too frequently degraded systems that will not provide the needed ecosystem services to ensure a future of sustainable agricultural production. The processes that have created this situation continue and are being accelerated by anthropogenic climate change. Increasing arboreal vegetation in these areas through agroforestry is an important strategy to conserve and improve their agroecosystems. Actinorhizal trees and shrubs in the Casurinaceae have a unique set of adaptations for heat and water stress, and/or infertile to hostile soils. Central Anatolia, Turkey is particularly at risk of increasing aridity and further degradation. Therefore, species of Allocasuarina and Casuarina have been evaluated for their potential use in agroecosystem improvement in semi-arid areas with a focus on Central Anatolia. Based on a semiquantitative environmental tolerance index and reported plant stature, eight species were identified as being of high (A. verticillata and C. pauper) to moderate (A. acutivalvis, A. decaisneana, A. dielsiana, A. huegeliana, C. cristata and C. obesa) priority for assessment, with none of these species having been adequately evaluated for agroforestry deployment in semi-arid agroecosystems in any context.
