“…Salinity has been reported to decrease leaf area tremendously and also showed profound changes in leaf anatomy in rice grown in-vitro [58] or in greenhouse [59] as verified by [60]. The ultra-structural observations briefed by [56] also ensured the inhibitory effect of salt on leaf thus hampering the photosynthetic efficiency: swelling of thylakoids followed by disruption of chloroplastids. Salinity was observed to exert severe detrimental effect on the mesophyll tissue even stretching its harmful effects to the vascular bundles.…”

“…The effect of salinity on plants is initiated by the osmotic effect characterized by lowered osmotic potential followed by later ionic effect causing ion toxicity. Studies conducted to interpret the response of rice at physiological level indicated chloroplast and mitochondria to be the most vulnerably affected organs among others [56]. Hence, chlorophyll content, changes in chlorophyll fluorescence (Fv/Fm) and membrane permeability are efficient and potential indicators for understanding the inhibitory effect of salt on the photosynthetic efficiency [20,57].…”

Salinity has been a key abiotic constraint devastating crop production worldwide. Attempts in understanding salt tolerance mechanisms has revealed several key enzymes and altered biochemical pathways inferring resistance to crop plants against salt stress. The past decades have witnessed extensive research in development of salt tolerant cultivars via conventional means, improvised by modern era molecular tools and techniques. Rice (Oryza sativa L) is the staple food crop across several countries worldwide. Being a glycophyte by nature, its growth is severely imparted in presence of excess salt. Rice is susceptible to salinity specifically at the early vegetative and later reproductive stages and the response of the crop to excessive salt toxicity at biochemical and molecular level as well as physiological level is well studied and documented. An understanding of the specific response of rice to ion accumulation at the toxic level can aid in identifying the key factors responsible for retarded growth and limited production of rice with the future scope of mitigating the same. The present review summarizes the differential responses of rice, in particular, to salt toxicity enumerating the detailed morphological, physiological, biochemical and molecular changes occurring in the plant. An attempt to explain salinity tolerance and its future scope and implications in screening for salt tolerance has also been elucidated in the present study.

“…Cell organelles such as chloroplasts and mitochondria in rice leaves are damaged by salinity stress (Rahman et al 2000). Thus, reduction in chlorophyll content and in the maximum potential quantum efficiency of PSII, measured as changes in chlorophyll fluorescence (F v /F m ) is related to the salinity-induced swelling and distortion of thylakoids, grana stacking, stroma and chloroplast envelope (Barhoumi et al 2007;Rahman et al 2000;Wang et al 2009;Yamane et al 2003Yamane et al , 2008.…”

Morpho-physiological variations in response to NaCl stress during vegetative and reproductive development of rice

The complex nature of plant resistance to adverse environmental conditions, such as salinity and drought requires a better understanding of the stress-induced changes that may be involved in tolerance mechanisms. Here we investigate stress-related morpho-physiological effects during vegetative and reproductive growth in two Japonica rice cultivars (Bomba and Bahia) exposed to a range of NaCl concentrations from the seedling stage. The stress-related detrimental effects were observed either earlier or to a higher extent in cv. Bomba than in Bahia. Damages to the photosynthetic apparatus were related to loss of chlorophyll (Chl) and to a decrease of the maximum potential efficiency of PSII (F v /F m ), affecting negatively net CO 2 assimilation rate (P N ). Stress-related leaf anatomical alterations were analysed during the vegetative and reproductive stages. The size of bulliform cells as well as dimensions related to the vascular system increased under mild stress but decreased in the longer term or under higher stress level. The pattern of the anatomical alterations observed at the reproductive stage under 20 mM NaCl was reflected in poor panicle development and yield loss, with effects more pronounced in cv. Bomba than in Bahia. In summary, our results show that some physiological and, particularly, leaf anatomical responses induced by NaCl stress are distinctive indicators of sensitivity to salt stress in rice cultivars.

“…In most saline soil, Na is a major ion that is present in high concentrations (Cumming and Elliot, 1991) and causes the reduction of plant growth and crop yield because of its ion toxicity. Excess salinity induces various detrimental effects on plants such as oxidative stress (Savouré et al, 1999;Zhu, 2001;Yamane et al, 2009), inhibition of photosynthetic activity (Meloni et al, 2003;Shabala et al, 2005) and ultrastructural damage (Rahman et al, 2000;Mitsuya et al, 2000Mitsuya et al, , 2003Yamane et al, 2003Yamane et al, , 2008, and fi nally arrests plant development and leads to plant death.…”

The effect of NaCl stress on the structure of leaf chloroplasts was investigated in several NAD-Malic enzyme (NAD-ME) and phosphoenolpyruvate carboxykinase (PCK) type C 4 plant species. Seedlings of the monocot species, except Zoysia japonica, grown in 300 mL pots were subjected to salt stress by adding 50 mL of 3% NaCl solution per day to the soil for 5 d after the fourth leaf blades were fully developed. Z. japonica and the dicot species, Amaranthus tricolor, were also treated with 3% NaCl in a similar manner from 5 wk after germination. Salt stress negatively affected the growth, chlorophyll content and chloroplast structure in all the species. At the ultrastructure level, swelling of thylakoids and disruption of envelopes were more or less observed in mesophyll cell (MC) chloroplasts after salt treatment. The structure of bundle sheath cell (BSC) chloroplasts, on the other hand, was hardly damaged under salt condition although stromal and starch areas were considerably decreased. Furthermore, salinity induced granal development in BSC chloroplasts in most species; the number of thylakoids per granum, granal indices and appressed thylakoid density in salt-treated plants were generally higher than those in control. Since the similar responses have also been reported in all NADP-ME type C 4 species investigated in our previous study, the high sensitivity to salt stress in MC chloroplasts and the granal development in BSC chloroplasts by salinity were considered to be common phenomena in all three C 4 subtypes.
