“…Functional screening of the Agrobacterium libraries identified 44 putative salt tolerance genes in B. gymnorrhiza. Miyama et al (2006) identified 14,842 expressed sequence tags from leaves and roots of B. gymnorrhiza under high salinity or hormone treatments. In total, 129 statistically confident genes were grouped into four clusters depending on their expressed sequence tag (EST) frequency and each group has a specific pattern of transcript profiling under high salinity.…”

Key message This review gives a comprehensive overview of adaptations of mangrove root system to the adverse environmental conditions and summarizes the ecological importance of mangrove root to the ecosystem. Abstract In plants, the first line of defense against abiotic stress is in their roots. If the soil surrounding the plant root is healthy and biologically diverse, the plant will have a higher chance to survive in stressful conditions. Different plant species have unique adaptations when exposed to a variety of abiotic stress conditions. None of the responses are identical, even though plants have become adapted to the exact same environment. Mangrove plants have developed complex morphological, anatomical, physiological, and molecular adaptations allowing survival and success in their high-stress habitat. This review briefly depicts adaptive strategies of mangrove roots with respect to anatomy, physiology, biochemistry and also the major advances recently made at the genetic and genomic levels. Results drawn from the different studies on mangrove roots have further indicated that specific patterns of gene expression might contribute to adaptive evolution of mangroves under high salinity. We also review crucial ecological contributions provided by mangrove root communities to the ecosystem including marine fauna.

“…Assembly of 14,842 high quality sequences generated 6,943 unique genes and 62.5% of such EST collection matched known proteins in Blast searching. Totally 129 statistically-confident genes were grouped into 4 clusters depending on their EST frequency and each group has specific pattern of transcript profiling under high salinity Miyama et al (2006) Salt-responsive transcript profilings of 7,029 unique genes in leaf and root tissues were monitored using microarray technique. Clustering generated at least six categories of transcript accumulating under saline condition; Some genes displayed similar salt-responsive patterns to those in other plants, indicating shared mechanisms in Bruguiera gymnorrhiza and other glycophytes.…”

Mangroves are woody plants which form the dominant vegetation in tidal, saline wetlands along tropical and subtropical coasts. The current knowledge concerning the most striking feature of mangroves i.e., their unique ability to tolerate high salinity is summarized in the present review. In this review, we shall discuss recent studies that have focused on morphological, anatomical, physiological, biochemical, molecular and genetic attributes associated with the response to salinity, some of which presumably function to mediate salt tolerance in the mangroves. Here we shall also review the major advances recently made at both the genetic and the genomic levels in mangroves. Salinity tolerance in mangroves depends on a range of adaptations, including ion compartmentation, osmoregulation, selective transport and uptake of ions, maintenance of a balance between the supply of ions to the shoot, and capacity to accommodate the salt influx. The tolerance of mangroves to a high saline environment is also tightly linked to the regulation of gene expression. By integrating the information from mangroves and performing comparisons among species of mangroves and non-mangroves, we could give a general picture of salt tolerance mechanisms of mangroves, thus providing a new avenue for development of salt tolerance in crop plants through effective breeding strategies and genetic engineering techniques.

“…Mehta et al ( 2005 ) reported that out of 1,841 EST clones from Avicennia marima leaf library, 26 novel genes were highly upregulated under salt stress. Through small-scale transcriptomics approach using suppression substractive hybridization (SSH), several novel salt-induced genes were identifi ed in Bruguiera gymnorhiza (Miyama et al 2006 ;Wong et al 2007 ;Ezawa and Tada 2009 ) and Aegiceras corniculatum , where 30 unique ESTs were reported (Fu et al 2005 ). Similarly, 27 % of 1,255 ESTs from both leaf and root tissues of Spartina alternifl ora represented stress response under salinity (Baisakh et al 2008 ).…”

Soil salinity is one of the most serious environmental factors that affect crop productivity worldwide. Inevitable global climate change leading to rise in sea water level would exacerbate degradation of irrigation systems and contamination of ground water resources, which render conventional agricultural practices impossible due to the sensitivity of most crops to salinity. Breeding for development of salt-tolerant crop plants has been a major challenge due to the complexity and multigenic control of salt tolerance traits. Halophytes are capable of surviving and thriving under salt at concentrations as high as 5 g/L, by maintaining negative water potential. Physiological and molecular studies have suggested that halophytes, unlike glycophytes, have evolved mechanisms, such as ion homeostasis through ion extrusion and compartmentalization, osmotic adjustments, and antioxidant production for adaptation to salinity. Employment of integrated approaches involving different omics tools would amplify our understanding of the biology of stress response networks in the halophytes. Translation of the knowledge and resources generated from halophyte relatives of crop plants through functional genomics will lead to the development of new breeds of crops that are suitable for saline agriculture.
