“…Recent research has also provided insights into the genetic response of Prunus species under drought, identifying key drought-responsive genes, including those directly related to water use efficiency (WUE). These include ERF023TF; LRR receptor-like serine/threonine-kinase ERECTA; and NF-YB3TF [203] as well as the gene ppa008651m coding for a LEA protein homolog to LEA D29 and PpDhn1 [201], and PpDhn2 and DREB2B [204]. No less important has been the characterization of natural sources of drought tolerance.…”

“…No less important has been the characterization of natural sources of drought tolerance. Bielsa et al [204] investigated differences in 48 Prunus species by evaluating leaf ash content and carbon isotope discrimination (∆ 13 C), which are strongly correlated with WUE. Almond and wild peach species showed the lowest ∆13C ratios, and therefore, greater WUE than hybrid genotypes, although, among the GN serie 'Monegro showed the greatest WUE [204].…”

The production and consumption of nuts are increasing in the world due to strong economic returns and the nutritional value of their products. With the increasing role and importance given to nuts (i.e., walnuts, hazelnut, pistachio, pecan, almond) in a balanced and healthy diet and their benefits to human health, breeding of the nuts species has also been stepped up. Most recent fruit breeding programs have focused on scion genetic improvement. However, the use of locally adapted grafted rootstocks also enhanced the productivity and quality of tree fruit crops. Grafting is an ancient horticultural practice used in nut crops to manipulate scion phenotype and productivity and overcome biotic and abiotic stresses. There are complex rootstock breeding objectives and physiological and molecular aspects of rootstock–scion interactions in nut crops. In this review, we provide an overview of these, considering the mechanisms involved in nutrient and water uptake, regulation of phytohormones, and rootstock influences on the scion molecular processes, including long-distance gene silencing and trans-grafting. Understanding the mechanisms resulting from rootstock × scion × environmental interactions will contribute to developing new rootstocks with resilience in the face of climate change, but also of the multitude of diseases and pests.

The production and consumption of nuts are increasing in the world due to strong economic returns and the nutritional value of their products. With the increasing role and importance given to nuts (i.e., walnuts, hazelnut, pistachio, pecan, almond) in a balanced and healthy diet and in the prevention of various diseases, breeding of the nuts species has also been stepped up. Most recent fruit breeding programs have focused on scion genetic improvement. However, the use of locally adapted grafted rootstocks also enhanced the productivity and quality of tree fruit crops. Grafting is an ancient horticultural practice use in nut crops to manipulate scion phenotype and productivity and overcome biotic and abiotic stresses.

Understanding the mechanisms resulting from rootstock × scion × environmental interactions will contribute to developing new rootstocks with resilience in the face of climate change, but also of the multitude of diseases and pests and of the possible increase of their aggressiveness. They will also have to offer the premises of economic production, respectively yield and the quality, according to multiple destinations of nuts in the current consumption and food industry, but also the increasing exigencies of the consumer market and the profile industry.

“…Entre estas destacan las obtenciones híbridas, procedentes del cruzamiento entre el almendro 'Garfi' [Prunus amygdalus Batsch, syn P. dulcis (Mill.)] y el melocotonero 'Nemared' [P. persica (L.) Batsch], 'Garnem', 'Felinem' y 'Monegro', seleccionadas en el Centro de Investigación y Tecnología Agroalimentaria de Aragón (CITA) cuyas características principales son el vigor, la resistencia a nematodos y la adaptación a suelos calcáreos (Felipe, 2009), así como su tolerancia a la sequía (Bielsa et al, 2016(Bielsa et al, , 2018a(Bielsa et al, y 2018b.…”

Se evaluó la respuesta a sequía de dos cultivares de melocotonero con distinta época de maduración, 'Ufo-3' y 'Fergold', injertados sobre el patrón híbrido almendro × melocotonero, 'Garnem', en los veranos de 2015 y 2016 en Murcia, España. En poscosecha, los árboles se sometieron a 5 días sin riego y, posteriormente, a 5 días de recuperación de riego. Se evaluó el estado hídrico del árbol, el intercambio gaseoso, así como el contenido en ácido abscísico (ABA) foliar. Se comprobó un descenso del contenido hídrico del suelo (CHS), que ocasionó la reducción del potencial hídrico foliar (PHF) y el cierre estomático. Reiniciado el riego, el estado hídrico de los árboles estresados fue recuperado. Se observó una correlación negativa entre el PHF y el uso eficiente del agua intrínseco (UEAi) en 2015, indicando una posible estrategia de tolerancia mediante la cual se conservase la capacidad fotosintética, a pesar de los bajos valores de conductancia estomática (gs) y PHF. Por otra parte, la regulación del cierre estomático observada en los árboles estresados no fue provocada por la acumulación de ABA. Esta evaluación agronómica permitirá una mayor comprensión del posible efecto del patrón 'Garnem' en la adaptación fisiológica y bioquímica a la sequía y su comportamiento en recuperación bajo condiciones de campo áridas de los cultivares de melocotonero injertados.
