Abscisic acid cross-talking with hydrogen peroxide and osmolyte compounds may regulate the leaf rolling mechanism under drought
Sezgin, Asiye; Altuntaş, Cansu; Sağlam, Aykut; Terzi, Rabiye; Demiralay, Mehmet; Kadıoğlu, Asım (Springer Heidelberg, 2018)Leaf rolling observed in some crops such as maize, rice, wheat and sorghum is an indicator of decreased water status. Moderate leaf rolling not tightly or early increases the photosynthesis and grain yield of crop cultivars ... -
Application of proline to root medium is more effective for amelioration of photosynthetic damages as compared to foliar spraying or seed soaking in maize seedlings under short-term drought
Demiralay, Mehmet; Altuntaş, Cansu; Sezgin, Asiye; Terzi, Rabiye; Kadıoğlu, Asım (TUBITAK Scientific & Technical Research Council Turkey, 2017)Exogenous proline (PRO) at low concentrations can enhance drought stress tolerance in different application modes such as application to rooting medium, foliar spray, and seed soaking. However, there is no information ... -
Application of sucrose modulates the expressions of genes involved in proline and polyamine metabolism in maize seedlings exposed to drought
Altuntaş, Cansu; Sezgin, Asiye; Demiralay, Mehmet; Terzi, Rabiye; Sağlam, Aykut; Kadıoğlu, Asım (ACAD Sciences Czech Republic, 2019)Sucrose, proline, and polyamines are compatible solutes accumulating in plant tissues and increasing cellular osmolarity under environmental stresses. These compatible solutes and hydrogen peroxide can function as signaling ... -

Exogenous acetone O-(4-chlorophenylsulfonyl) oxime alleviates Cd stress-induced photosynthetic damage and oxidative stress by regulating the antioxidant defense mechanism in Zea mays
Demiralay, Mehmet (Springer, 2022)Cadmium (Cd) toxicity in leaves decreases their photosynthetic efficiency by degrading photosynthetic pigments, reducing the activity of gas exchange parameters and photosystem II (PSII), and producing reactive oxygen ... -
Exogenous alpha lipoic acid can stimulate photosystem II activity and the gene expressions of carbon fixation and chlorophyll metabolism enzymes in maize seedlings under drought
Sezgin, Asiye; Altuntaş, Cansu; Demiralay, Mehmet; Cinemre, Salih; Terzi, Rabiye (Elsevier GMBH, 2019)Protective compounds such as non-enzymatic antioxidants, osmolytes and signal molecules have been applied to plants exposed to various environmental stresses to increase their stress tolerance. However, there are not ... -
Exogenous ascorbic acid mitigates accumulation of abscisic acid, proline and polyamine under osmotic stress in maize leaves
Terzi, Rabiye; Kalaycıoğlu, Ebru; Demiralay, Mehmet; Sağlam, Aykut; Kadıoğlu, Asım (Springer Heidelberg, 2015)The effects of osmotic stress (polyethylene glycol, PEG 6000) and exogenous ascorbic acid (ASC) on abscisic acid (ABA), some osmolytes (proline and polyamine), and gene expression of polyamine metabolic enzymes arginine ... -
Hydrogen peroxide extends postharvest life of Ctenanthe setosa leaf cuts under osmotic stress by reducing leaf rolling
Sağlam, Aykut; Kalaycıoğlu, Ebru; Güven, Funda Gül; Saruhan, Neslihan; Kadıoğlu, Asım; Demiralay, Mehmet (Korean Soc Horticultural Science, 2014)Reducing effects of exogenous hydrogen peroxide on leaf rolling in detached leaves of Ctenanthe setosa were studied. The leaves were kept in H2O2 solutions ranging from 0 to 1 mM for 48 h and then, osmotic stress was applied ... -
Increased dehydrin level decreases leaf rolling grade by altering the reactive oxygen species homeostasis and abscisic acid content in maize subjected to osmotic stress
Saruhan Güler, Neslihan; Terzi, Rabiye; Demiralay, Mehmet; Öztürk, Kamil; Kadıoğlu, Asım (Springer Nature, 2022)Abstract Dehydrins (DHNs) are stress proteins involved in the development of protective reactions in plants against dehydration. The relationship between DHNs and morphological responses such as leaf rolling in plants ... -
Leaf anatomical notes on Cirsium Miller (Asteraceae, Carduoideae) from Turkey
Özcan, Melahat; Demiralay, Mehmet; Kahriman, Aydın (Springer Wien, 2015)Here, we describe the leaf anatomical characters of 26 Cirsium taxa (33 accessions) native to the northeast region of Turkey, with the aim of evaluating their taxonomic significance within the taxa. Leaf anatomies of all ... -
Leaf rolling reduces photosynthetic loss in maize under severe drought
Sağlam, Aykut; Kadıoğlu, Asım; Demiralay, Mehmet; Terzi, Rabiye (Univ Zagreb, 2014)Effects of leaf rolling (LR) on maize photosynthesis under severe drought stress were studied in two cultivars with opposite drought responses, Batem 56-55 (drought tolerant) and Batem 51-52 (drought sensitive). Drought ... -
Proline-stimulated signaling primarily targets the chlorophyll degradation pathway and photosynthesis associated processes to cope with short-term water deficit in maize
Altuntaş, Cansu; Demiralay, Mehmet; Muslu, Asiye Sezgin; Terzi, Rabiye (Springer, 2020)Increased photosynthetic efficiencies in genotypes with greater proline level and in crops treated with proline under water deficit have been reported in recent years, but the biochemical and molecular mechanisms of this ... -
