“…The involvement of the xanthophyll cycle in the protection of the photosynthetic structure by dissipating excess energy is well understood (Ramachandra Reddy et al, 2004;Li et al, 2010). Se-caused alterations in various photosynthesis related parameters have been recorded in different plant species like lettuce (Xue et al, 2001), soybean (Djanaguiraman et al, 2005), and potatoes (Germ et al, 2007). Selenium toxicity is attributed to its similarity to sulfur (S).…”

“…Both selenium deficiency and toxicity are proposed as vital issues worldwide (Terry et al, 2000), mainly because of a narrow boundary between its requirement and toxicity levels (Germ et al, 2007;Pilon-Smits and Quinn, 2010). There is a positive correlation between the likelihood of some important issues such as cancers and selenium deficiency (Diwadkar-Navsariwala et al, 2006;White and Broadley, 2009).…”

IntroductionAscorbic acid (AsA) is one of the most critical low molecular weight antioxidants and has control over crucial processes, including the cell cycle and cell wall expansion (Noctor and Foyer, 1998). Ascorbic acid, a water soluble compound, is known as a major redox buffer, one of the most abundant antioxidants, and a required cofactor for several enzymes. Its multiple implications in various critical aspects of key physiological processes like cell division, growth, signal transduction, photosynthesis, and hormone biosynthesis are well documented (Gallie, 2013). Ascorbate is regarded as the first line of defense against detrimental effects of active oxygen species (AOS), and protects plant cells from various abiotic and biotic oxidative stressors (Suza et al., 2010). It has been stated that foliarly supplemented ascorbate may be an effective treatment for improving tolerance in stress exposed plants in arid and semi-arid regions (Dolatabadian et al., 2009). In addition, it has been proposed that various crucial compounds, including phenolics, carotenoids, tocopherols, chlorophyll, and ascorbic acid all possess a key role in the prevention of different diseases related to oxidative stress such as cardiovascular diseases, cancer, atherosclerosis, inflammation, neurodegenerative diseases, diabetes, and other chronic diseases (Šircelj et al., 2010).

“…Previous research has indicated the effects of Se on plant growth under different conditions including drought (Germ et al 2007). Elemental Se is poisonous to the plant, however after absorption by root system and through metabolic processes it is converted to selenomethionine, and selenocysteine amino acids, which are not poisonous to the plant (Pilon-Smits et al 2009).…”

The effects of selenium (Se) on plant growth under drought stress and in the presence of micronutrients are yet to be investigated. Hence, in a field experiment in 2007 the effects of Se and micronutrients including iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), boron (B) and molybdenum (Mo) were evaluated on corn (Zea mays L.) grain yield under drought stress. Main-and sub-plots were devoted to irrigation (control and water stressed at the eight-leaf, blister and grain filling stages) and micronutrients treatments, respectively. Micronutrients were foliarly applied at 2 l ha -1 at the six-leaf stage, one week before tasseling, using a corn fertilizer, called biomin containing (on the basis of dry weight percentage) Fe (2.6), Zn (4

“…The effect(s) of selenium foliar spraying on photosynthesis has been evaluated using potato plants exposed or not to sodium selenate, and to a concomitant drought regime (Germ et al 2007). To this aim, 50 days old potato plants were sprayed or not with sodium selenate (53 lM); photosynthetic carbon dioxide fixation, as well as Photosystem II (PSII) quantum yield, were then determined 2 and 4 weeks after selenium aspersion.…”

Selenite transiently represses transcription of photosynthesis-related genes in potato leaves

et al. 2007

A striking response of potato leaves to aspersion with selenite was observed at the transcriptional level by means of cDNA microarrays analysis. This response is characterized by a general transient repression of genes coding for components of photosynthetic systems and of other light-regulated genes. In particular, maximal repression was observed 8 h after selenite aspersion, while 24 h after the treatment a complete recovery of normal transcriptional levels was detected. Another general feature of the transcriptional response to selenite is represented by the transcriptional induction of genes related to amino acid metabolism, and to stress defense; interestingly, two genes coding for glutathione S-transferases were found early-induced upon selenite treatment.
