“…Previous studies have shown that the concentration of b-ODAP increased in grass pea seeds exposed to drought (Hussain et al 1997;Yan et al 2006), and the increase in the b-ODAP concentration in various tissues of grass pea has been considered an important physiological response to drought stress (Xing et al 2001;Zhou et al 2001;Haque et al 2011). Other studies have shown that water shortage significantly reduced biomass and seed yield of grass pea compared with a well-watered control, but had no effect on b-ODAP concentration in seeds, resulting in much less accumulation of b-ODAP in water-stressed grass pea (Gusmao et al 2012;Kong et al 2014).…”

24-epibrassinolide (EBL) is a growth regulator that promotes crop growth and yield, especially under water stress, but its effect on grass pea (Lathyrus sativus L.), a legume crop widely recognized as adapted to rainfed environments, is unknown. The aim of the present study was to investigate the effect of exogenously-applied EBL on growth, yield and accumulation of b-N-oxalyl-L-a, bdiaminopropionic acid (b-ODAP)-a neurotoxin that can induce lathyrism in animals and humans-in grass pea under well-watered (WW) and water-stressed conditions. The first experiment conducted in a growth chamber showed that EBL application increased plant height and leaf area of well-watered [WW, 85 % field capacity (FC)] grass pea seedlings and in those in which the soil dried from 85 to 30 % FC. In two pot experiments conducted under a rainout shelter, three water regimes-soil water contents maintained at (1) 85 or 80 % FC, (2) 50 % FC, and (3) 35 % FC-were imposed. In the first rainout shelter experiment, root/soil drenching with EBL significantly increased aboveground dry weight (DW) and water use efficiency (WUE) compared with plants without EBL at 85 and 50 % FC, but did not significantly affect grain yield. In a second rainout shelter experiment, water treatments were imposed from the vegetative phase to maturity and EBL treatment significantly increased aboveground DW, grain yield, b-ODAP concentration and amount, and WUE in the 80 and 50 % FC water regimes. It is concluded that exogenously-applied EBL can stimulate growth and WUE in grass pea when WW and moderately water stressed, and also stimulates b-ODAP production such that the concentration in the grain is similar or even higher.

“…Crop yields show considerable variability among locations, years and genotypes; however, environmental conditions are not as important as genotypes . Nonetheless, stressors such as salinity and drought have been found to increase ODAP concentrations . In addition, there is a possible relationship between changes in β ‐ODAP concentrations and Rhizobium growth.…”

The influences of eight metal ions (i.e., Na+, Ca2+, Ag+, Co2+, Cu2+, Al3+, Zn2+, and Mn4+) on mycelia growth and palmarumycins C12 and C13 production in liquid culture of the endophytic fungus Berkleasmium sp. Dzf12 were investigated. Three metal ions, Ca2+, Cu2+ and Al3+ were exhibited as the most effective to enhance mycelia growth and palmarumycin production. When calcium ion (Ca2+) was applied to the medium at 10.0 mmol/L on day 3, copper ion (Cu2+) to the medium at 1.0 mmol/L on day 3, aluminum ion (Al3+) to the medium at 2.0 mmol/L on day 6, the maximal yields of palmarumycins C12 plus C13 were obtained as 137.57 mg/L, 146.28 mg/L and 156.77 mg/L, which were 3.94-fold, 4.19-fold and 4.49-fold in comparison with that (34.91 mg/L) of the control, respectively. Al3+ favored palmarumycin C12 production when its concentration was higher than 4 mmol/L. Ca2+ had an improving effect on mycelia growth of Berkleasmium sp. Dzf12. The combination effects of Ca2+, Cu2+ and Al3+ on palmarumycin C13 production were further studied by employing a statistical method based on the central composite design (CCD) and response surface methodology (RSM). By solving the quadratic regression equation between palmarumycin C13 and three metal ions, the optimal concentrations of Ca2+, Cu2+ and Al3+ in medium for palmarumycin C13 production were determined as 7.58, 1.36 and 2.05 mmol/L, respectively. Under the optimum conditions, the predicted maximum palmarumycin C13 yield reached 208.49 mg/L. By optimizing the combination of Ca2+, Cu2+ and Al3+ in medium, palmarumycin C13 yield was increased to 203.85 mg/L, which was 6.00-fold in comparison with that (33.98 mg/L) in the original basal medium. The results indicate that appropriate metal ions (i.e., Ca2+, Cu2+ and Al3+) could enhance palmarumycin production. Application of the metal ions should be an effective strategy for palmarumycin production in liquid culture of the endophytic fungus Berkleasmium sp. Dzf12.
