        Screening of ‘King’ mandarin (Citrus nobilis Lour) ×Poncirus trifoliata ((L.) Raf.) hybrids as salt stress-tolerant citrus rootstocks

        Mary-Rus Martínez-Cuenca,Maria Angeles Forner-Giner,Amparo Primo-Capella 한국원예학회 2021 Horticulture, Environment, and Biotechnology Vol.62 No.3

        This work evaluates new citrus hybrid tolerance to salt stress compared to Carrizo citrange. Growth parameters, ion concentration,photosynthetic parameters, leaf water relation, plant damage and proline concentration were assessed in plantsirrigated with 0 (control) or 60 mM of NaCl for 60 days. Some hybrids presented marked salt-stress symptomatology likesharp decreases in plant biomass and RGR parameter, and high leaf burn and abscission percentages. While Cl − accumulationin most salinised genotypes was recorded in all the plant fractions, accumulation occurred in some hybrids only in their aerialorgans. Stomatal conductance also lowered under salt conditions in all the hybrids, whereas the internal CO 2 concentration(Ci) tended to increase. Salt stress lowered the leaf water potentials in all the 0501 hybrids. As a response, the salinisedplants induced proline accumulation. The main trait that improved salt tolerance in some genotypes is apparently linked withthe imbalance among Cl − , Na + and K + ions, especially enhanced K + uptake and transport rates which delay plant damage.

        Key role of boron compartmentalisation-related genes as the initial cell response to low B in citrus genotypes cultured in vitro

        Mary-Rus Martínez-Cuenca,Amparo Primo-Capella,Maria Angeles Forner-Giner 한국원예학회 2019 Horticulture, Environment, and Biotechnology Vol.60 No.4

        This work compared the expression of the main B transport-related genes (some members of the aquaporin family - NIP5 , TIP5 and PIP1 - and some effl ux-B transporters - BOR1 and BOR4 -), and the response of some physiological parameters in two citrus species [ Citrus macrophylla W. (CM) and Citrus aurantium L. (CA)] under moderate and low boron (B) conditions. Seedlings were cultured “in vitro” in media supplemented with 50 or 0 μM H 3 BO 3 . NIP5 , BOR1 and PIP1 expressions were enhanced by low B levels in both genotypes. TIP5 was down-regulated in the roots and leaves of the CA0 seedlings, and in the roots of CM0. BOR4 also lowered in the roots of both species at 0 μM H 3 BO 3 . Consequently, citrus species showed a common tolerance mechanism to low B conditions based on the synergism among transport channel NIP5, non-selective aquaporin PIP1 and transporter BOR1, and the impairment of genes TIP5 and BOR4 related with tolerance responses to B-toxic conditions. However, the CA genotype displayed low B symptoms earlier than CM (reduced plant biomass, length, relative growth rate and chlorophyll content). Proline concentration was higher in CM0 than in CA0 leaves, while the latter also enhanced malonaldehyde content. Although both plants had similar B concentrations, they diff ered in B content and B partitioning fractions. Whereas the CA genotype was more aff ected by lack of B treatment as more B was needed inside the cell, the more minimal need of cell B in CM favoured its allocation in the insoluble fraction and allowed growth in this genotype. In conclusion, B compartmentalisation seems critical in tolerance to low B level in citrus.
