Tetraploidy Enhances Boron-Excess Tolerance in Carrizo Citrange (Citrus sinensis L. Osb. × Poncirus trifoliata L. Raf.)
UNLABELLED Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and tetraploid (4x) plants of Carrizo citrange (Citrus sinensis L. Osb. × Poncirus trifoliata L. Raf.), a widely used citrus rootstock. Wit...
متن کاملResponses of trifoliate orange (Poncirus trifoliata (L.) Raf.) to continuously and gradually increasing NaCl concentration
The effect of continuous or gradual stress due to NaCl on in vitro growth, proline and sugar accumulation and nutrient acquisition of trifoliate orange (Poncirus trifoliata (L.) Raf.) explants was studied. Apical shoot tips obtained from previous subculture were transferred to a Murashige and Skoog nutrient medium for proliferation and were exposed to continuous or gradual salinity stress for 4...
متن کاملClonal Propagation of Carob (ceratonia Siliqua L., Fabaceae)
Mature seeds of carob tree (Ceratonia siliqua L.) were germinated on hormone free MS medium. Efforts were made to develop multiple shoots by using axillary buds of in vitro grown seedlings on MS medium fortified with different concentrations of BA singly and BA in combination with IAA or GA3. Axillary buds produced single shoot with a moderate amount of callus at the base of the explant after c...
متن کاملCoumarins form the seeds of Poncirus trifoliata L.
In a general research program on furocoumarins and coumarins from this plant we recently de scribed 4 the identification of the five furocouma rins, bergapten, imperatorin, isopimpinellin, prangenin and prangenin hydrate in the seeds obtained from ripe fruits of plants cultivated in the area of Padua. We are now reporting the isolation of two coumarinic derivatives, i. e. 7-geranyloxycoumarin...
متن کاملCharacterization of FRO1, a pea ferric-chelate reductase involved in root iron acquisition.
To acquire iron, many plant species reduce soil Fe(III) to Fe(II) by Fe(III)-chelate reductases embedded in the plasma membrane of root epidermal cells. The reduced product is then taken up by Fe(II) transporter proteins. These activities are induced under Fe deficiency. We describe here the FRO1 gene from pea (Pisum sativum), which encodes an Fe(III)-chelate reductase. Consistent with this pro...
