The objective of this work was to evaluate the physiological and production parameters of soybean (Glycine max) cultivars of determinate and indeterminate growth habits, in three levels of soil moisture. Three cultivars of determinate growth habit and three of indeterminate growth, at the beginning of the reproductive stage, were subjected to three levels of soil moisture: control, moisture at field capacity; moderated, 50% of the control level; and severe, 25% of the control level. Leaf gas exchange, xylem-water potential, chlorophyll content, chlorophyll a fluorescence, plant dry matter, and grain yield per plant were evaluated. The cultivars of indeterminate growth habit showed the greatest values for stomatal conductance and CO2 assimilation at the severe treatment, which led to the higher water consumption, in the morning, and to the lower xylem water potential, in the afternoon; however, there was no gain of soybean dry matter. In both growth types, the intensity and duration of the severe level of soil moisture were not able to change the chlorophyll fluorescence. Soybean cultivars of both growth habits, subjected to severe levels of soil moisture from flowering to pod insertion, show no significant change for dry matter and grain yield. |

Cowpea mild mottle virus (CpMMV), the causal agent of stem necrosis disease, has drawn attention of soybean producers in recent years due to yield losses in the main producing regions of Brazil. Serological methods for viral detection require the use of an antiserum of good quality to achieve specificity and sensitivity. The entire coat protein gene of a Brazilian CpMMV isolate was cloned into a bacterial expression vector and transformed into Escherichia coli BL21::DE3 for in vitro expression. The coat protein, fused to a His-tag, was purified under denaturing conditions by affinity chromatography using a Ni-NTA resin. After renaturation, the integrity and identity of the purified recombinant protein was confirmed by SDS-Page and MALDI-ToF/ToF mass spectrometer analyses. A rabbit was immunized with increasing amounts of the recombinant protein. The specificity and sensitivity of the antiserum was demonstrated by Western blot and indirect ELISA assays. The polyclonal antisera raised against recombinant coat protein proved to be a reliable tool for CpMMV detection. |
