Resumen: Predicted increases in atmospheric concentration of carbon dioxide (CO2)
coupled with increased temperatures and drought are expected to strongly
influence the development of most of the plant species in the world, espe-
cially 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 cla-
veryi mycorrhizal fungus, which is a desert truffle with increasingly commer-
cial interest. Although both plant and fungi are known to be well adapted to
dry conditions, it is still uncertain how the increase in atmospheric CO2 will
influence them. In this article we have addressed the physiological
responses of H. almeriense × T. claveryi mycorrhizal plants to increases in
atmospheric CO2 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 photosyn-
thesis limitation. High atmospheric CO2 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

Resumen: The cultivation of desert truffle Terfezia claveryi using Helianthemum almeriense as a host plant has recently become a solid
alternative crop in the Mediterranean region due to its adaptation to arid and semiarid ecosystems, which are expected to increase
during the following years because of climate change. However, management models are still being developed in order to
improve and stabilize the production, which varies greatly from one year to another. According to gatherers and farmers, one
of the key factors for desert truffle production is the plant phenology in spring, which, in turn, depends on environmental
conditions. In this manuscript, we have characterized the physiological, morphological, and molecular responses of the mycorrhizal
plants in spring, coinciding with the fructification period of the plant and fungal species. Thanks to this characterization, a
sigmoidal relationship between stomatal conductance and vapor pressure deficit (VPD)was found,which can be used as amarker
of plant phenological switch. In order to confirmthat this phenology status is related to desert truffle fructification, this marker has
been successfully correlated to total truffle production. The results of this manuscript suppose a big step forward that will help to
develop management models for the desert truffle crop.

Resumen: 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.
