The almond x peach hybrid H1 has the potential to be used as a peach (Prunus persica L.) rootstock, because it its highly resistant to drought, dry soils with low fertility, nematods, root asphyxia, and chlorosis induced by Fe deficiency. Since a hybrid propagated by seeds would produce segregation, for maintaining the desired plant traits the hybr...

A successful in vitro propagation system for the Garnem rootstock (almond × peach) was optimized. Axillary buds were successfully established in Murashige and Skoog (MS) free-hormone. In proliferation stage, the effect of three culture media including MS, Driver and Kuniyuki (DKW) and Lloyd and McCown (WPM) supplemented with BA (0.5, 1 and 2 mg.l-1...
Analysis of the transcriptomic changes produced in response to hypoxia in root tissues from two rootstock Prunus genotypes differing in their sensitivity to waterlogging: resistant Myrobalan 'P.2175' (P. cerasifera Erhr.), and sensitive 'Felinem' hybrid [P. amygdalus Batsch × P. persica (L.) Batsch] revealed alterations in both metabolism and regul...
Resumen: El trabajo deriva de un estudio sobre el negocio del durazno (Prunus persica) en Santa María Tlahuitoltepec, en la Sierra Norte del Estado de Oaxaca en donde el cultivo de frutos afines a la región constituye una fuente importante para la obtención de ingresos, beneficia a empleados, productores, intermediarios y comerciantes. Con base al...
Graft incompatibility is a significant problem for development of new Prunus rootstocks. Recently, several authors have reported that phenylpropanoid metabolism is related with this phenomenon. The aim of the present work was to analyze the gene expression patterns of the 4-Coumarate:CoA ligase genes in compatible and incompatible graft combination...
Peach was domesticated in China more than four millennia ago and from there it spread world-wide. Since the middle of the last century, peach breeding programs have been very dynamic generating hundreds of new commercial varieties, however, in most cases such varieties derive from a limited collection of parental lines (founders). This is one reaso...

Murashige-Skoog (MS) or Lloyd and McCown (WPM) medium were used for micropropagation of Cissus tiliacea, an herb plant with potential in agriculture and pharmacology; in both medium similar results for shoot regeneration, number of leaves, leaves nodes, and adventitious roots were observed; only formation of callus was influenced (p ≤ 0.05) by the medium. For in vitro multiplication, benzyl adenine (BA) was added to WPM at 0, 0.5, 1.0, 1.5 or 2.0 mg L -1 and we used three types of explants that is basal, medium an upper. BA at 0 and 0.5 mg L -1 resulted in higher size and well developed plantlets; moreover, those concentrations allowed 1.2 or 1.6 roots per vitro plant. Those explants cultured in 1.5 or 2.0 BA resulted in callus development. Type of explant did not influence the evaluated explants responses. Rooting was evaluated in MS adding naphthalene acetic acid (NAA), indol butiric acid (IBA) or indol acetic acid (IAA) at 0.5 mg L -1; the higher number of secondary roots and the diameter of the main root was induced by NAA, but IBA resulted in longer main roots. Present results suggested that micropropagation of C. tiliaceae might be and alternative for conservation and multiplication of this wild plant.
