Drought and heat stresses are two of the most frequent environmental factors that take place simultaneously in the field constraining global crop productivity. Metabolism reconfiguration is often behind the adaptation of plants to adverse environmental conditions. Carrizo citrange and Cleopatra mandarin, two citrus genotypes with contrasting ability to tolerate combined heat and drought conditi...

Drought and high temperatures are two major abiotic stress factors that often occur simultaneously in nature, affecting negatively crop performance and yield. Moreover, these environmental challenges induce oxidative stress in plants through the production of reactive oxygen species (ROS). Carrizo citrange and Cleopatra mandarin are two citrus genotypes with contrasting ability to cope with the...

Here the isolation and characterization of CitAMT1 cDNA from citrange Troyer (Citrus sinensis L. OsbeckxPoncirus trifoliata Blanco) is reported, suggesting that this belongs to the AMT gene family, which is involved in the high-affinity transport system (HATS). Results show that in Citrus plants, the HATS is much more dependent on the light conditions and C status of the roots than the low-affi...

Abstract Environmental changes derived from global warming and human activities increase the intensity frequency of stressful conditions for plants. Multiple abiotic factors acting simultaneously enhance stress pressure drastically reduce plant growth, yield, survival. Stress combination causes a specific situation that induces particular response different to sum responses individual stresses....

Salinity is one of the most destructive environmental challenges for citriculture worldwide, and all climate change scenarios are predicting an increased impact salinity on citrus orchards. Citrus cultivars grown as grafts various rootstocks to provide specific adaptation abiotic stress tolerance major diseases such tristeza virus. To understand rootstock–scion interactions with regard salinity...

BACKGROUND AND AIMS Since salinity and drought stress can occur together, an assessment was made of their interacting effects on leaf water relations, osmotic adjustment and net gas exchange in seedlings of the relatively chloride-sensitive Carrizo citrange, Citrus sinensis x Poncirus trifoliata. METHODS Plants were fertilized with nutrient solution with or without additional 100 mm NaCl (sal...

Essential nutrients for citrus [‘Bingo’ ( Citrus reticulata , Blanco)] production are important different functions, including photosynthesis, resistance to disease, and productivity. During the past 15 20 years, in Florida has significantly declined as a result of devastating greening disease also called huanglongbing (HLB). Therefore, greenhouse study was conducted 2 starting 2018, at Univers...

Mediterranean basin and other citrus-growing areas, such as Florida or California, are among the most vulnerable regions to impacts of global warming. Therefore, citrus will be likely subjected increasing periods water scarcity combined with high temperatures that impair plant growth, development yield. In industry, grafting is used improve varietal characteristics, abiotic stress tolerance. Pr...

Abstract New approaches for developing disease-resistant genetically modified organisms have included specific targets gene expression to enhance the chances pathogen control. Gene driven by phloem-derived Citrus sinensis promoters could be evaluated and compared with induced a strong constitutive promoter in same tissue, leading production of transgenic sweet oranges potentially more resistant...
