“…Plants grown in forest and exposed to sun radiation inside greenhouse and under midday sun, showed a restricted Pn compared to sun plants (Fig. 4A) probably due to the photoinhibition in order of few hours (Karim et al, 2003). On the other hand, leaves of C. fissilis sunny plants had the ability to respond to strong light.…”

“…Similar results were observed in wheat by Almeselmani et al (2006) under changes in irradiance and high temperature in all the genotypes, however, tolerant genotypes maintained comparatively higher chlorophyll content and showed less reduction compared to other genotypes under increasing temperature. A decrease of total chlorophyll content with high temperature implies a lowered capacity for light harvesting (Karim et al, 2003;Afzal et al, 2014 The reduced chlorophyll stability index more destruction of chlorophyll under high temperature and poor translocation of photosynthates from the sink to the source in the present study could be the other reasons for decrease in seed yield (Table 3) in the present investigation. The results were in agreement with those of Subrahamanyam and Rathore (1994) who observed that high temperature during reproductive stage significantly inhibited the import of photosynthates by both upper and lower pods of terminal reaceme and thereby reduced sink strength.…”

“…Heat stress can cause several alterations at cellular and sub-cellular levels and the response of the plants depends upon the growth stage, intensity, and duration of the exposure to heat stress (Karim et al, 2003;Sung et al, 2003;Mansoor and Naqvi 2013). The direct effects of heat stress include denaturation of proteins and enzymes (Kepova et al, 2005) and damage to membranes while its indirect effects may include inactivation of enzymes present in the mitochondria and chloroplasts, impaired protein synthesis, degradation of proteins, and disruption of membrane integrity (Karim et al, 2003;Howarth 2005;Kumar et al, 2011).…”

A study was conducted to examine the physiological responses and yield of contrasting mungbean genotypes viz, MH 421, MH 318 and Basanti differing in their sensitivity to high temperature raised in earthen pots (30 cm diameter) filled with 5.5 kg of dune sand (Typic Torrispamments) under screen house conditions. High temperature stress was given by manipulating sowing dates i.e. normal (12 th March, 2013) and late (29 th March, 2013) sown. Samplings were done at 3 and 7 days after exposure (DAE) of temperature above 35°C at reproductive stage. Sampling below 35°C temperature was considered as control. High temperature resulted in decreased chlorophyll stability index, chlorophyll and carotenoid contents, relative stress injury and yield. Sensitive genotypes showed large reductions in aforementioned physiological traits. On the other hand, tolerant genotype (MH 421) maintained higher chlorophyll stability index, chlorophyll and carotenoid contents, relative stress injury and yield. After 7 days of exposure to high temperature under late sown, A significant decrease was noticed in genotypes MH 318 and Basanti.

India is the largest producer of mungbean and accounts for about 65% of the average of India and 54% of the world production (Lambrides et al., 2007). Mungbean is one of main protein sources for the vegetarian diet. Mungbean may also be sown as an inter crop or as a green manure or cover crop. It fetches high price in the market and is a preferred pulse crop for the farmers. Mungbean crop grown in warm seasons confronts with high temperature at different growth stages in different seasons. The variation in temperature requirements and temperature extremes varies widely for different cultivars of the same species, and among difference species. The reproductive phase of many crop species is relatively more sensitive to heat stress than the vegetative phase (Martiniello and Teixeira da Silva, 2011).

“…In the other hand, the photoinhibition because of high temperatures and high light was not relation with ELIP expression level because this parameter had not significant differences between 25 and 35 ºC. No essays to analyze ELIP expression in long time conditions have been done using high light and high temperatures; hence more studies are necessary to know if ELIP expression is induced in these conditions, since plants are more tolerant to photoinhibition under high temperatures but in acclimation conditions (Karim et al, 2003).…”

Early light induced proteins (ELIP) are a type of proteins which are expressed before than other chloroplast proteins in the presence of light. These proteins have been studied in a large number of annual species such as pea (Pisum sativum L.), barley (Hordeum vulgare L.) and Arabidopsis sp. In perennials plants the studies about ELIPs are very scarce. The possible photoprotective function of the ELIPs has motivated the interest in investigating the presence of this type of proteins in a perennial plant such as grapevine (Vitis vinifera L.) and if their characteristics differ from those found in annual plants. In this paper a comparative study was conducted on the ELIPs expression in grapevine and pea to investigate whether there are differences regarding to temperature and light intensity conditions necessary for maximum ELIP expression in each species and for studying in each case the relationship between ELIP expression and photoinhibition degree. The results of this study showed that the maximum ELIPs expression was reached from 25 ºC and 1000 µmol PAR m -2 s -1 in both species. Above these values the expression remained constant. Regarding the temperature and light intensity effect on the photoinhibition degree, it was observed that temperature produced inverse relation in grapevine but no relation with pea. On the other hand, the light intensity produced direct relation in both grapevine and pea. The light intensity effect on ELIP expression suggests that these proteins may have a photorepairing role of the photosynthetic system, but the effect of temperature on the ELIP expression in short-term stress may be associated rather to the optimum conditions for their synthesis.
