Hormonal changes in relation to biomass partitioning and shoot growth impairment in salinized tomato (Solanum lycopersicum L.) plants

• Alfonso A Albacete, Michel Edmond Ghanem, +6 authors Francisco Pérez-Alfocea
• Journal of experimental botany
• 2008

Following exposure to salinity, the root/shoot ratio is increased (an important adaptive response) due to the rapid inhibition of shoot growth (which limits plant productivity) while root growth is… (More)

Hormonal changes during salinity-induced leaf senescence in tomato (Solanum lycopersicum L.)

• Michel Edmond Ghanem, Alfonso A Albacete, +5 authors Francisco Pérez-Alfocea
• Journal of experimental botany
• 2008

Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in… (More)

Rootstock-mediated changes in xylem ionic and hormonal status are correlated with delayed leaf senescence, and increased leaf area and crop productivity in salinized tomato.

• Alfonso A Albacete, Cristina Martínez-Andújar, +7 authors Francisco Pérez-Alfocea
• Plant, cell & environment
• 2009

Tomato crop productivity under salinity can be improved by grafting cultivars onto salt-tolerant wild relatives, thus mediating the supply of root-derived ionic and hormonal factors that regulate… (More)

Root-targeted biotechnology to mediate hormonal signalling and improve crop stress tolerance

• Michel Edmond Ghanem, Imène Hichri, +7 authors Francisco Pérez-Alfocea
• Plant Cell Reports
• 2011

Since plant root systems capture both water and nutrients essential for the formation of crop yield, there has been renewed biotechnological focus on root system improvement. Although water and… (More)

Interaction between hydrogen peroxide and plant hormones during germination and the early growth of pea seedlings.

• Gregorio Barba-Espín, P Diaz-Vivancos, +5 authors J. A. Hernandez
• Plant, cell & environment
• 2010

Hydrogen peroxide (H(2)O(2)) increased the germination percentage of pea seeds, as well as the growth of seedlings in a concentration-dependent manner. The effect of H(2)O(2) on seedling growth was… (More)

Hormonal and metabolic regulation of source-sink relations under salinity and drought: from plant survival to crop yield stability.

• Alfonso A Albacete, Cristina Martínez-Andújar, Francisco Pérez-Alfocea
• Biotechnology advances
• 2014

Securing food production for the growing population will require closing the gap between potential crop productivity under optimal conditions and the yield captured by farmers under a changing… (More)

Stomatal and mesophyll conductances to CO2 are the main limitations to photosynthesis in sugar beet (Beta vulgaris) plants grown with excess zinc.

• Ruth Sagardoy, Sandra Ortiz Vázquez, +5 authors Fernando A. Morales
• The New phytologist
• 2010

*The effects of zinc (Zn) toxicity on photosynthesis and respiration were investigated in sugar beet (Beta vulgaris) plants grown hydroponically with 1.2, 100 and 300 microM Zn. *A photosynthesis… (More)

Root-synthesized cytokinins improve shoot growth and fruit yield in salinized tomato (Solanum lycopersicum L.) plants

• Michel Edmond Ghanem, Alfonso A Albacete, +8 authors Francisco Pérez-Alfocea
• Journal of experimental botany
• 2011

Salinity limits crop productivity, in part by decreasing shoot concentrations of the growth-promoting and senescence-delaying hormones cytokinins. Since constitutive cytokinin overproduction may have… (More)

Response of nitrogen fixation in relation to nodule carbohydrate metabolism in Medicago ciliaris lines subjected to salt stress.

• Imène Ben Salah, Alfonso A Albacete, +6 authors Chédly Abdelly
• Journal of plant physiology
• 2009

The effect of salt stress on nitrogen fixation, in relation to sucrose transport towards nodules and other sink organs and the potential of sucrose breakdown by nodules, was investigated in two lines… (More)

Antioxidant enzyme activities and hormonal status in response to Cd stress in the wetland halophyte Kosteletzkya virginica under saline conditions.

• Rui-Ming Han, Isabelle Lefévre, +8 authors Stanley Lutts
• Physiologia plantarum
• 2013

Salt marshes constitute major sinks for heavy metal accumulation but the precise impact of salinity on heavy metal toxicity for halophyte plant species remains largely unknown. Young seedlings of… (More)
