The objectives of this research were to evaluate (1) the performance of soybean mutant lines under drought stress conditions, and (2) the genetic diversity and relationship among the mutant lines using SSR markers. The field evaluation was conducted during the dry season of 2011 and 2012 at the experimental Farm of Mataram University, West Nusa Tenggara, Indonesia. The field experiment was set up in a randomized block design. Ten mutant lines and two control varieties were evaluated in four replications. Genetic distance among evaluated lines were determined based on allelic diversity analysis using 40 simple sequence repeat (SSR) loci. Under drought stress conditions, two mutant lines, Kdl3 and Kdl8, showed a better performance compared to the other ones. The high yielding mutant lines were Kdl3 and Kdl8, which yielded 1.75 t ha-1 and 1.69 t ha-1, respectively, compared to the parent and national control, Panderman 1.43 t ha-1 and Muria 1.32 t ha-1. These mutant lines required 30.75 to 32 days to flower and 79.75 to 83.75 day to harvest with relatively short plant height 28.25 and 23.35 cm respectively. Those mutant characters were better than those of the other three mutants, the original parents, and the control soybean species. Since the evaluated soybean mutant lines yielded more under drought stress conditions than the standard varieties, they can be used and registered as drought-tolerant soybean mutants. Moreover, the evaluated soybean accessions showed a wide genetic distance. The accessions were clustered into two groups according to their genetic background, namely group I (the Panderman with three mutant lines) and group II (the Muria with two mutant lines). Twenty-three out of 40 evaluated SSR loci,

“…Similarly, temperature extremes, high light levels, pH excursions, and stress-driven accumulations Table I. of metabolites with which cofactors react all directly accelerate diverse types of spontaneous cofactor damage (Treadwell and Metzler, 1972;Baggott, 2000;Mills et al, 2006;Marbaix et al, 2011). Abiotic stresses can also promote cofactor damage indirectly by altering compartmentation (Akhtar et al, 2010;Mohammadi et al, 2012) by inducing enzymes that break down cofactors (Rapala-Kozik et al, 2008;Higa et al, 2012) and by creating harsh cellular conditions in which enzymes that normally act on other substrates become more promiscuous (Piedrafita et al, 2015) and mistakenly attack cofactors. Figure 1 uses color-coded arrows to show the site and nature of damage reactions that vitamins and cofactors can undergo in physiological conditions, and Table I catalogs the reactions corresponding to the arrows.…”

Does Abiotic Stress Cause Functional B Vitamin Deficiency in Plants?

et al. 2016

B vitamins are the precursors of essential metabolic cofactors but are prone to destruction under stress conditions. It is therefore a priori reasonable that stressed plants suffer B vitamin deficiencies and that certain stress symptoms are metabolic knock-on effects of these deficiencies. Given the logic of these arguments, and the existence of data to support them, it is a shock to realize that the roles of B vitamins in plant abiotic stress have had minimal attention in the literature (100-fold less than hormones) and continue to be overlooked. In this article, we therefore aim to explain the connections among B vitamins, enzyme cofactors, and stress conditions in plants. We first outline the chemistry and biochemistry of B vitamins and explore the concept of vitamin deficiency with the help of information from mammals. We then summarize classical and recent evidence for stress-induced vitamin deficiencies and for plant responses that counter these deficiencies. Lastly, we consider potential implications for agriculture.

“…However, soybean growth, development, and yield are greatly affected by several abiotic stressors, such as flooding [19], drought [24], and salinity [32]. Particularly, in soybeans, drought stress occurring at the early stage of pod development significantly increases the rate of pod abortion, thus decreasing final seed yield [22].…”

Exogenous low-dose hydrogen peroxide enhances drought tolerance of soybean (Glycine maxL.) through inducing antioxidant system

Hydrogen peroxide (H 2 O 2 ) functions as a signal molecule in plants under abiotic and biotic stress. In this study, the role of exogenous H 2 O 2 in improving drought tolerance in two soybean cultivars (Glycine max L. Merrill) differing in their tolerance to drought was evaluated. Plants were grown in plastic pots with normal irrigation in a phytotron. Four weeks after radicle emergence, either 1 mM H 2 O 2 or distilled water was sprayed as foliar onto the leaves of each plant, after drought stress was applied. Leaf samples were harvested on the 4 th and 7 th days of the drought. Antioxidant-related enzyme activity, such as the superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR), hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) content was measured during the drought period. Drought stress decreased leaf water potential, relative water content and photosynthetic pigment content but enhanced lipid peroxidation and endogenous H 2 O 2 concentration. By contrast, exogenous low dose H 2 O 2 improved water status, pigment content and lipid peroxidation under drought stress. Endogenous H 2 O 2 concentration was reduced by exogenous H 2 O 2 as compared to drought treatment alone. H 2 O 2 pre-treatment induced all the antioxidant enzyme activities, to a greater extent than the control leaves, during drought. H 2 O 2 pretreatment further enhanced the activities of antioxidant enzymes in the tolerant cultivar compared to the sensitive cultivar. Results suggested that low dose H 2 O 2 pre-treatment alleviated water loss and H 2 O 2 content and increased drought stress tolerance by inducing the antioxidant system.
