“…Terfezia claveryi Chatin is one of the best known and appreciated desert truffle, due to its great flavor, nutritional and antioxidant properties (Murcia et al 2002, 2003) and because it is cultivable (Honrubia et al 2001, Morte et al 2008). From the last 20 years, T. claveryi cultivation using Helianthemum almeriense Pau, as host plant, has expanded gradually and it is currently considered an alternative crop for arid and semiarid regions (Morte et al 2017, Andrino et al 2019). Furthermore, its adaptation to drylands makes it a crop with a great future, as the potential areas for its cultivation are expected to increase due to climatic change (Schlesinger et al 1990, Lavee et al 1998, Huang et al 2016).…”

Predicted increases in atmospheric concentration of carbon dioxide (CO 2) coupled with increased temperatures and drought are expected to strongly influence the development of most of the plant species in the world, especially in areas with high risk of desertification like the Mediterranean basin. Helianthemum almeriense is an ecologically important Mediterranean shrub with an added interest because it serves as the host for the Terfezia claveryi mycorrhizal fungus, which is a desert truffle with increasingly commercial interest. Although both plant and fungi are known to be well adapted to dry conditions, it is still uncertain how the increase in atmospheric CO 2 will influence them. In this article we have addressed the physiological responses of H. almeriense × T. claveryi mycorrhizal plants to increases in atmospheric CO 2 coupled with drought and high vapor pressure deficit. This work reports one of the few estimations of mesophyll conductance in a drought deciduous Mediterranean shrub and evaluates its role in photosynthesis limitation. High atmospheric CO 2 concentrations help desert truffle mycorrhizal plants to cope with the adverse effects of progressive drought during Mediterranean springs by improving carbon net assimilation, intrinsic water use efficiency and dispersal of the species through increased flowering events.

“…The first desert truffle to be cultivated was Terfezia claveryi in symbiosis with Helianthemum almeriense in the south-east of Spain (Honrubia et al 2001;Morte et al 2008). T. claveryi fructification usually occurs 2-3 years after plantation, depending on site suitability, season and the framework of plantation, as well as management practices, specially irrigation and weed elimination (Morte et al 2017). In these plantations, the carpophores fructified yearly and the crop increased with time providing an average of 350-400 kg/ha and year (Morte et al 2008;2017).…”

Desert truffles have become an alternative agricultural crop in semiarid areas of the Iberian Peninsula due to their much appreciated edible value and their low water requirements for cultivation. Although most studies related to desert truffle production point to the sole importance of precipitation, this work is the first systematic study carried out to characterize whether other important agroclimatic parameters, for example reference evapotranspiration, soil water potential, relative air humidity %, aridity index or air vapour pressure deficit, may have an impact on a desert truffle production in an orchard with mycorrhizal plants of Helianthemum almeriense × Terfezia claveryi for 15 years from the plantation. The results show for the first time that T. claveryi production has two key periods, during its annual cycle: autumn (September to October) and spring (end of March). The aridity index and soil water potential seem to be the most manageable parameters in the field and can be easily controlled by applying irrigation during the abovementioned periods. Agroclimatic parameters can influence the final crop a long time before the desert truffle fruiting season contrary to what happens with other edible mycorrhizal mushrooms. Four different models to manage desert truffle plantations are proposed based on these agroclimatic parameters in order to optimize and stabilize carpophore fructifications over the years.

“…The type of association formed between this species and Helianthemum genus plants is an ectendomycorrhiza, characterized by the presence of both intercellular Hartig net and intracellular hyphae penetrating the cortex cells [2]. Furthermore, biotechnological advances have allowed cultivation and subsequent commercialization of this species using Helianthemum almeriense Pau as host plant [3,4].…”

Terfezia claveryi Chatin is a mycorrhizal fungus that forms ectendomycorrhizal associations with plants of Helianthemum genus. Its appreciated edibility and drought resistance make this fungus a potential alternative crop in arid and semiarid areas of the Mediterranean region. In order to increase the knowledge about the biology of this fungus in terms of mycorrhiza formation and response to drought stress, a catalase from T . claveryi (TcCAT-1) has been purified to apparent homogeneity and biochemically characterized; in addition, the expression pattern of this enzyme during different stages of T . claveryi biological cycle and under drought stress conditions are reported. The results obtained, together with the phylogenetic analysis and homology modeling, indicate that TcCAT-1 is a homotetramer large subunit size monofunctional-heme catalase belonging to Clade 2. The highest expression of this enzyme occurs in mature mycorrhiza, revealing a possible role in mycorrhiza colonization, but it is not upregulated under drought stress. However, the H 2 O 2 content of mycorrhizal plants submitted to drought stress is lower than in well watered treatments, suggesting that mycorrhization improves the plant’s oxidative stress response, although not via TcCAT-1 upregulation.
