Abstract Cyclophilin (CYP) plays an important role in plant response to stress, and OsCYP2, one gene of cyclophlilin
family, is involved in auxin signal transduction and stress signaling in rice. However, the mechanism that OsCYP2
is involved in rice response to low temperature is still unclear. We identified a new OsCYP2 allelic mutant, lrl3,
with fewer lateral roots, and the differences in shoot height, primary root length and adventitious root length
increased with the growth process compared to the wild-type plant. Auxin signaling pathway was also affected
and became insensitive to gravity. The transgenic rice plants with over-expression of OsCYP2 were… More >

Abstract Olive productivity should be improved through stimulating nutrition, particularly under poor fertility soils. Consequently, the objective of this study was to assess the efficacy of applying organic and bio-fertilizers on the physiological growth, yield and fruit quality of olive trees under newly reclaimed poor-fertility sandy soil in an arid
environment. During a field experiment carried out at El-Qantara, North Sinai, Egypt over two consecutive seasons (2019–2020 and 2020–2021), olive Kalamata trees were evaluated under three organic fertilizer treatments
alone or in combination with three bio-fertilizers treatments. Organic fertilizer was applied as goat manure
(16.8 kg/tree/year), or olive pomace (8.5 kg/tree/year)… More >

Abstract Cadmium (Cd) and Mercury (Hg) is among the heavy metals most hazardous for plant and human health.
Known to induce oxidative stress in plants and disbalance equilibrium in the antioxidant defence system, these
metals alter plant growth and cause damage at the cellular and molecular levels. Soybean is an important oilseed
crop that is raised in soils often contaminated by Cd and Hg. The comparative studies on the deleterious effect of
Cd and Hg and the defence system of antioxidants were not studied earlier in soybean plant. In this study, soybean plants were exposed to Cd (100 µM CdCl2) and… More >

Abstract Banana is a tropical crop cultivated in warm places. Chilling stress in Egypt is making banana crops less
productive. Abscisic acid (ABA), a key plant hormone, regulates metabolic and physiological processes and
protects plants from a variety of stresses. In vitro growing banana shoots were pre-treated with ABA at four
concentrations (0, 25, 50, and 100 mM) and chilled at 5°C for 24 h, followed by a six-day recovery period at
25°C. By comparing ABA treatments to both positive and negative controls, physiological and biochemical
changes were investigated. Chilling stress (5°C) caused a considerable increase in lipid peroxidation and ion… More >
