“…However, S. chilense showed lesser destruction profile comparatived to cultivated species, particularly, at 14 and 21 days of treatment. Our finding are in line with Kordrostami et al (2017) who also noted a decrease in the total content of Chl and carotenoids under stressed condition.…”

Salinity intrusion is one of the biggest problems in the context of sustainable agricultural practices. The major concern and challenge in developing salt-resistance in cultivated crops is the genetic complexity of the trait and lack of natural variability for stress-responsive traits. In this context, tomato wild relatives are important and have provided novel alleles for breeding abiotic stress tolerance including salt tolerance. We provide here a case study, involving tomato wild relative Solanum chilense and cultivated variety Solanum lycopersicum , carried out under high salt stress to investigate comparative transcriptional regulation mediating ROS homeostasis and other physiological attributes. Salt dependent oxidative stress in S. lycopersicum was characterized by a relatively higher H 2 O 2 content, generation of O 2 •− , electrolytic leakage and lipid peroxidation whereas reduced content of both ascorbate and glutathione. On the contrary, the robust anti-oxidative system in the S. chilense particularly counteracted the salt-induced oxidative damages by a higher fold change in expression profile of defense-related salt-responsive genes along with the increased activities of anti-oxidative enzymes. We conclude that S. chilense harbours novel genes or alleles for salt stress-related traits that could be identified, characterized, and mapped for its possible introgression into cultivated tomato lines.

In this study, the anti-stress capabilities of the foliar application of chitosan, dissolved in four different organic acids (acetic acid, ascorbic acid, citric acid and malic acid) have been investigated on tomato (Solanum lycopersicum L.) plants under salinity stress (100 mM NaCl). Morphological traits, photosynthetic pigments, osmolytes, secondary metabolites, oxidative stress, minerals, antioxidant enzymes activity, isozymes and protein patterns were tested for potential tolerance of tomato plants growing under salinity stress. Salinity stress was caused a reduction in growth parameters, photosynthetic pigments, soluble sugars, soluble proteins and potassium (K+) content. However, the contents of proline, ascorbic acid, total phenol, malondialdehyde (MDA), hydrogen peroxide (H2O2), sodium (Na+) and antioxidant enzyme activity were increased in tomato plants grown under saline conditions. Chitosan treatments in any of the non-stressed plants showed improvements in morphological traits, photosynthetic pigments, osmolytes, total phenol and antioxidant enzymes activity. Besides, the harmful impacts of salinity on tomato plants have also been reduced by lowering MDA, H2O2 and Na+ levels. Chitosan treatments in either non-stressed or stressed plants showed different responses in number and density of peroxidase (POD), polyphenol oxidase (PPO) and superoxide dismutase (SOD) isozymes. NaCl stress led to the diminishing of protein bands with different molecular weights, while they were produced again in response to chitosan foliar application. These responses were varied according to the type of solvent acid. It could be suggested that foliar application of chitosan, especially that dissolved in ascorbic or citric acid, could be commercially used for the stimulation of tomato plants grown under salinity stress.

“…The salinity can cause negative effects on the plant growth and development. This may be explained by the decrease in the activity of meristem cells and disruption of important physio-biochemical processes of plant growth [17]. The results showed that rice lines screened in this study responded variably to the salt tolerance.…”

Rice (Oryza spp. L., 1753) is the most staple food cereal in Senegal. However, national production is low and cannot cover the country needs. Salinity limits rice production in Senegal River valley which is main rice growing area in Senegal. This study assessed salinity tolerance of 30 rice lines at vegetative stage in station of Senegalese Institute for Agricultural Research (ISRA) at Ndiol in Senegal River valley. Experimental design adopted was alpha lattice with three rehearsals. Observations were performed on plant height, main stem development and number of tillers. The level of salinity and pH in surface water, groundwater and soil were monitored. The results indicate that salinity affects plant height and tillering ability and among 30 lines, four were identified highly tolerant to salinity at vegetative stage. These are the varieties HK11-NDIOL-11-LON-1, D20-ART20-ARS-1, D56-ARS-NCRIB-1-1 and HK72-NIONO-5-1-1. The decision to incorporate these varieties in salinity tolerance breeding programs would depend on salt tolerance screening across all growing stages.
