“…In olive, the presence of leaves in the cuttings seems to play a minor role in adventitious root formation for some cultivars , but an inhibitory effect was described in other cases when leaves and buds are removed (Avidan and Lavee, 1978;Caballero and Nahlawi, 1979;Fontanazza and Rugini, 1977). The presence of leaves has been reported to significantly improve callus and root formation, and to decrease outgrowth of buds to shoots (Suárez et al, 1999). However, auxin treatments still seem to exert a stronger influence on rooting success (Pio et al, 2005).…”

Olive (Olea europaea) is one of the most important fruit species in the Mediterranean basin, where 95% of the world's olive orchards are planted, and it has become an economically valuable crop worldwide, due to an increasing interest in olive oil for human consumption. New olive orchards are being planted outside the Mediterranean, calling for an effort to identify the genotypes best adapted to the new conditions. However, some olive cultivars remain difficult to propagate, which significantly reduces the capacity to use the full genetic diversity of the species. Improving rooting ability in cuttings from recalcitrant olive cultivars has become a critical topic, which implies fundamental research on the anatomy, physiology, biochemistry and genetics of the adventitious root formation process. Besides, the existence of different rooting behaviors among olive cultivars also makes the species a candidate model plant for these studies. Olive propagation techniques evolved through time from field-or nursery-planted hardwood cuttings, to semi-hardwood cuttings in greenhouses under mist, and, more recently, to in vitro culture techniques. Nevertheless, research about adventitious root formation carried on each propagation method was mostly based on trial and error approaches. Researchers have mainly investigated different factors involved in the process of adventitious rooting by testing their effect in the rooting capacity of different cultivars, leading to a high dispersion and fragmentation of the available information. The goal of this review is to present the most relevant results achieved on adventitious root formation in olive cuttings, aiming to provide an integrated perspective of the current knowledge.

“…Olive branches were removed and transported in a humid piece of cloth to a greenhouse. Cuttings were produced as explained by Suárez et al (). Briefly, 18 cm length and 4–6 cm diameter cuttings were treated with indolbutyric acid (IBA) 3500 ppm by immersing the cutting base for 10 s in a 1:1 (v:v) IBA hydro‐alcoholic solution.…”

1The adaptation capacity of olive trees to different environments is well recognized. 2 However, the presence of microorganisms in the soil is also a key factor in the response of 3 these trees to drought. The objective of the present study was to elucidate the effects of 4 different arbuscular mycorrhizal (AM) fungi coming from diverse soils on olive plant 5 growth and water relations. Olive plants were inoculated with native AM fungal 6 populations from two contrasting environments, i.e. semi-arid -Freila (FL) and humid -7 Grazalema (GZ) regions, and subjected to drought stress. Results showed that plants grew 8 better on GZ soil inoculated with GZ-fungi, indicating a preference of AM fungi for their 9 corresponding soil. Also under these conditions, the highest AM fungal diversity was 10 found. However the highest root hydraulic conductivity (Lp r ) value was achieved by plants 11 inoculated with GZ fungi and growing in FL soil under drought conditions. So, this AM 12 inoculum also functioned in soils from different origins. Nine novel aquaporin genes were 13 also cloned from olive roots. Diverse correlation and association values were found among 14 different aquaporin expressions and abundances and Lp r , indicating how the interaction of 15 different aquaporins may render diverse Lp r values. 16 17

The olive branches were removed and transported in a humid piece of cloth to a greenhouse and the cuttings were produced as described in Suárez et al (1999).

Olive trees are known for their capacity to adapt to drought through several phenotypic and molecular variations, although this can vary according to the different provenances of the same olive cultivar. We confronted the same olive cultivar from two different location in Spain: Freila, in the Granada province, with low annual precipitation, and Grazalema, in the Cadiz province, with high annual precipitation, and subjected them to five weeks of severe drought stress. We found distinctive physiological and developmental adaptations among the two provenances. Thus, trees from Freila subjected to drought stress exhibited increasing root dry weights and decreasing leaf numbers and relative stem heights. On the other hand, the treatment with drought in Grazalema trees reduced their leaf chlorophyll contents, but increased their relative stem diameter and their root hydraulic conductivity. The physiological responses of Freila tree roots to drought were linked to different molecular adaptations that involved the regulation of genes related to transcription factors induced by ABA, auxin and ethylene signaling, as well as, the action of a predicted membrane intrinsic protein (MIP). On the other hand, the responses of Grazalema trees were related with different root genes related to oxidation-reduction, ATP synthesis, transduction and posttranslational regulation, with a special mention to the cytokinins signaling through the transcript predicted as a histidinecontaining phosphotransfer protein. Our results show that olive trees adapted to dry environments will adjust their growth and water uptake capacity through transcription factors regulation, and this will influence the different physiological responses to drought stress.
