“…Lin et al [15] reported that the S. kawagutii genome contains diverse set of antioxidative response genes such as SOD and ascorbate peroxidases. While most of the studies on SOD and CAT enzymes in Symbiodinium suggested these enzymes play a major role in coping with an increase of sea temperature to prevent coral bleaching [91][92][93], a number of studies in other organisms revealed that these enzymes may act in response to other types of environmental stress such as salinity, exposure to hydrogen peroxide and drought conditions [94][95][96]. Apart from the antioxidative response, cell adhesion proteins also play a role in maintaining coral-Symbiodinium symbiosis interaction [9].…”

Abstract:Dinoflagellates are essential components in marine ecosystems, and they possess two dissimilar flagella to facilitate movement. Dinoflagellates are major components of marine food webs and of extreme importance in balancing the ecosystem energy flux in oceans. They have been reported to be the primary cause of harmful algae bloom (HABs) events around the world, causing seafood poisoning and therefore having a direct impact on human health. Interestingly, dinoflagellates in the genus Symbiodinium are major components of coral reef foundations. Knowledge regarding their genes and genome organization is currently limited due to their large genome size and other genetic and cytological characteristics that hinder whole genome sequencing of dinoflagellates. Transcriptomic approaches and genetic analyses have been employed to unravel the physiological and metabolic characteristics of dinoflagellates and their complexity. In this review, we summarize the current knowledge and findings from transcriptomic studies to understand the cell growth, effects on environmental stress, toxin biosynthesis, dynamic of HABs, phylogeny and endosymbiosis of dinoflagellates. With the advancement of high throughput sequencing technologies and lower cost of sequencing, transcriptomic approaches will likely deepen our understanding in other aspects of dinoflagellates' molecular biology such as gene functional analysis, systems biology and development of model organisms.

“…In spite of these deleterious effects, plants present different degrees of tolerance to salinity, conferred by biochemical pathways, which can alleviate the negative effect of salt toxicity; amongst them: (I) retention and acquisition of water mediated by osmotically-active metabolites (mainly proline, glycinebetaine or sugars) (Singh et al, 2014); (II) maintenance of ion homeostasis (Rivero et al, 2014;Razzaghi et al, 2015); (III) induction of antioxidant systems (Ashraf et al, 2012;Hu et al, 2012;Wang et al, 2012;Fini et al, 2014); (IV) over production of hormones (Krasensky and Jonak, 2012;Yoshida et al, 2014) or (V) synthesis of specific stress-associated molecules such as heat-shock proteins (Wang et al, 2004;Krasenski and Jonak, 2012;Pérez-Salamò et al, 2014) and late embryogenesis abundant proteins (Parida andDas, 2005, Radíc et al, 2013). In view of the complexity of salinity tolerance, differences on salt sensitivity occur not only among species, but sometimes even genotypes belonging to the same species perform differently under salinity (Shabala and Munns, 2012).…”

The performance of a salt-tolerant pepper (Capsicum annuum L.) accession (A25) utilized as a rootstock was assessed in two experiments. In a first field experiment under natural salinity conditions, we observed a larger amount of marketable fruit (+75%) and lower Blossom end Root incidence (-31%) plants, which had a constitutive enhanced root apparatus and 2.6-fold higher proline content under salinity, did not show alterations in photosynthesis and growth and MDA levels increased only slightly. Our results underline that salt tolerance in A/A25 grafted plants could be mediate by (I) the maintenance of root sink strength and (II) the markedly increased proline levels that could balance cell osmotic pressure thus protecting enzymatic stability from salttriggered damage.

“…L.perenne and C. murale are salt tolerant species that could protect themselves against different toxicity (Holm et al, 1997andGuertin, 2003. Hu et al (2012) attributed the response of L.perenne against salinity stress to an antioxidant gene that maintain the biological process on the molecular level.…”

Habitat diversity is one of the attractive concepts in ecology that reflects the wellbeing of ecological systems. A total of 30 stands were chosen to represent habitat diversity of El-Harra Oasis. Poaceae, fababceae and astraceae were the most common families with 33 species out of 79 species belonging to 29 families. Therophytes and Hemicryptophytes were the most common life forms with 72 % of the species recorded. Chorology of all non-cultivated taxa was investigated. Species richness, Shannon and Simpson diversity indices and evenness was calculated for each stand. Eighteen soil parameters were investigated and results showed large variation among stands. Seven vegetation groups were obtained from the Two-way cluster analysis classification. Environmental parameters correlation with vegetation groups were determined using DCA and DCCA. Significant factors were detected by one way analysis of variance among the seven vegetation groups. Results showed that soil salinity indicators, soil moisture content and soil particles were the most critical factors affecting the ecological diversity in El-Harra Oasis. Indicator species of the seven habitats were halotolreants or halophytes. Managing water resources and agriculture schemes should reduce the magnitudes of salinity problem in El-Harra Oasis.
