“…Under waterlogging conditions, some studies have reported changes in ABA concentrations in several species, including alfalfa leaves (Medicago sativa L.; Castonguay et al, 1993), tobacco leaves (Nicotiana tabacum L.; Hurng et al, 1994), pea leaves (Pisum sativum L.; Jackson et al, 1988), tomato (Solanum lycopersicum L.; Else et al, 1995), Gerbera jamesonii Adlam (Olivella et al, 2000); Citrus (Arbona and Gómez-Cadenas, 2008); and Malus spp. (Bai et al, 2011).…”

Agriculture is severely impacted by water stress due either to excess (hypoxia/anoxia) or deficit of water availability. Hypoxia/anoxia is associated with oxygen (O 2 ) deficiency or depletion, inducing several anatomical, morphological, physiological, and molecular changes. The majority of these alterations are adaptive mechanisms to cope with low O 2 availability; among them, alterations in shoot length, aerenchyma formation and adventitious roots have been described in several studies. The aim of this review was to address the association between abscisic acid (ABA) and ethylene in function of water availability in plants. The major physiological responses to low O 2 are associated with changes in root respiration, stomatal conductance, photosynthesis, and fermentation pathways in roots. In addition, several changes in gene expression have been associated with pathways that are not present under normal O 2 supply. The expression of ethylene receptor genes is up-regulated by low O 2 , and ethylene seems to have a crucial role in anatomical and physiological effects during hypoxia/anoxia. During O 2 depletion, ethylene accumulation down-regulates ABA by inhibiting rate-limiting enzymes in ABA biosynthesis and by activating ABA breakdown to phaseic acid. With regard to water deficit, drought is primarily sensed by the roots, inducing a signal cascade to the shoots via xylem causing physiological and morphological changes. Several genes are regulated up or down with osmotic stress; the majority of these responsive genes can be driven by either an ABA-dependent or ABA-independent pathway. Some studies suggest that ethylene shuts down leaf growth very fast after the plant senses limited water availability. Ethylene accumulation can antagonize the control of gas exchange and leaf growth upon drought and ABA accumulation.

“…On the other hand, there was significant correlation between biomass (expressed by density and basal area) and distance to river. Some studies in laboratory scale (Jackson 1979;Tang and Kozlowski 1982;Save and Serrano 1986;Hurng et al 1994;Ismail and Noor 1996) flooding decrease the primary biomass productivity. This is probably physiologically of mechanism and processes in plant-tissue was not working properly under water stress condition.…”

Mirmanto E (2010) Vegetation analyses of Sebangau peat swamp forest, Central . The vegetation analysis study has been made in Sebangau peat-swamp forest, Central Kalimantan. Eight permanent plots of 50-m x 50-m were set-up distribute from close to the river with shallow peat-layer up to the inland with relatively deep peat-layer. Enumeration of trees (GBH > 15 cm) was conducted in all of 8 plots. Overall there are 133 species (taxa) were recorded within 8 plots belong to 34 families where Dipterocarpaceae, Clusiaceae, Myrtaceae and Sapotaceae were the most dominant family. Out of all species recorded, Combretocarpus rotundatus, Palaquium leiocarpum, Stemonurus scorpioides and Tristania whittiana were the most dominant species. Two community's types namely Combretocarpus rotundatus-Shorea balangeran community and Palaquium leiocarpum-Eugenia densinervium community were recognized and they distributed in slightly different habitat condition. The sequence of these two communities' shows significantly related to both distances to river and peat-depth. In addition there was indication the presence of habitat preference among tree species.

“…ABA has been investigated as a hormone potentially involved in submergence responses in several plant species, including both dicots and monocots (Hook et al , 1988; Hoson et al , 1993; Hurng et al , 1994; Lee et al , 2009). Consistent with previous reports, our data confirmed that ABA levels decreased upon submergence at both developmental stages (Fig.…”

Plants need to attune stress responses to the ongoing developmental programs to maximize their efficacy. For instance, successful submergence adaptation is often associated to a delicate poise between saving resources and their expenditure to activate measures that allow stress avoidance or attenuation. We observed a significant decrease in submergence tolerance associated with aging in Arabidopsis thaliana, with a critical step between two and three weeks of post-germination development. This sensitization to flooding was concomitant with the transition from juvenility to adulthood. Transcriptomic analyses indicated that a group of genes related to ABA and oxidative stress response was more expressed in juvenile plants than in adult ones. These genes are induced by endomembrane tethered ANAC factors that were in turn activated by submergence-associated oxidative stress. A combination of molecular, biochemical and genetic analyses showed that these genes are located in genomic regions that move towards a heterochromatic state with adulthood, as marked by lysine 4 dimethylation of histone H3. We concluded that, while the mechanism of flooding stress perception and signal transduction were unaltered between juvenile and adult phases, the sensitivity that these mechanisms set into action is integrated, via epigenetic regulation, into the developmental programme of the plant.
