Abstract Purpose: Phytophthora sojae does not infect the nonhost maize (Zea mays L.) but could infect the nonhost common bean (Phaseolus vulgaris L.). Soybean seed exudates participate in mediating host resistance to P. sojae before infection. This study aimed to elucidate the role of nonhost seed exudates in mediating nonhost resistance to P. sojae before infection. Methods: The response behavior of P. sojae zoospores to the seed exudates was determined using an assay chamber and a concave slide, and the proteomes of P. sojae zoospores treated with the seed exudates were analysed with the tandem mass tag (TMT) method. The key proteins were quantified by parallel reaction monitoring (PRM).Results: Maize seed exudates exerted a repellent effect on zoospores, whereas common bean seed exudates did not exhibit any attraction to zoospores but could dissolve the cysts. The key proteins related to zoospores chemotaxis showed no significant changes in response to maize seed exudates, but the key proteins in arachidonic acid pathway were downregulated and controlled the repellent behavior of zoospores. Proteins protecting the cell membrane structure were significantly downregulated in zoospores responding to common bean seed exudates, which confirmed the bacteriolytic effect of common bean seed exudates on cysts. Conclusion: Maize and common bean seed exudates mediate part of the nonhost resistance via different mechanisms prior to P. sojae infection. The immune of maize to P. sojae is due to the repellent effect of maize seed exudates on zoospores. Common bean seed exudates participate in mediating nonhost resistance by dissolving cysts.

Phytophthora sojae does not infect nonhost maize (Zea mays) but infects nonhost common bean (Phaseolus vulgaris) under inoculation. Soybean seed exudates participate in mediating host resistance to P. sojae prior to infection. This study aims to elucidate the role of seed exudates in mediating the nonhost resistance to P. sojae prior to infection. The behaviors of P. sojae zoospores in response to the seed exudates were determined using an assay chamber and a concave slide. The proteomes of P. sojae zoospores in response to the seed exudates were analyzed with the tandem mass tag (TMT) method. The key proteins were quantitatively verified by parallel reaction monitoring (PRM). Maize seed exudates exerted a repellent effect on zoospores. This result explains why zoospores sense repelling signaling molecules that weaken and strongly inhibit chemotaxis signals in the phosphatidylinositol signaling pathway and arachidonic acid metabolism pathway. Common bean seed exudates did not exhibit any attraction to the zoospores because the G protein signaling pathway, had no significant change. The proteins protecting the cell membrane structure were significantly downregulated, and the early apoptosis signal glutathione was enhanced in zoospores responding to common bean seed exudates, which resulted in dissolution of the cysts. Maize and common bean seed exudates mediate part of the nonhost resistance to P. sojae via different mechanisms prior to infection. The immunity of maize to P. sojae is due to the repellent effect of maize seed exudates on zoospores. Common bean seed exudates participate in mediating nonhost resistance by dissolving cysts.

Swietenia Mahagoni

Swietenia mahagoni is a timber forestry plants have allelopathy toxic, can interfere with the growth of surrounding plants. This study aimed to determine the effects of extracts from various parts of Swietenia mahagoni on seed germination of green beans and corn. This research was conducted at the Laboratory of Silviculture, an extract from a litter, fresh leaves, bark and roots of the Swietenia mahagoni plant and given to the seed germination green beans and corn. The results showed that the extract of fresh leaves and roots Swietenia mahagoni inhibit seed germination green beans and corn, while the provision of litter no effect. Green bean seed has a higher durability of the maize seed to allelopathy of root Swietenia mahagoni.

Abstract: Among the factors that affect seedling emergence and crop establishment are seed germination and vigor, which has an important influence on the establishment of the initial plant population and development, and may affect crop yield. Based on this background the objective of this research work was to evaluate the effects of seed vigor of common bean seed lots and its effects on crop grain yield. The treatments consisted of six seed lots of common bean, which were composed by different combinations of high and low vigor seeds. Seed lots were assessed by germination and vigor tests (first count of germination, electrical conductivity and accelerated aging). A field experiment was conducted in a randomized block design, with plots of six lines of five meters and were evaluated for grain yield at harvest. It was concluded that seed vigor affects common bean grain yield; the use of low vigor seeds results in grain yield reductions of up to 20%.

Natural coagulants from a crude water extract of common bean seed showed very good efficiency of turbidity removal from water of ~89 % under optimal coagulation conditions, which were determined using response surface methodology (RSM). However, they also increased the content of organic matter in treated model water by ~66 %, which is the main drawback of usage of natural coagulants, in general. Thus, ultrafiltration was applied for processing of the crude water extract in order to separate biomolecules, which exhibit the coagulation activity. Four fractions obtained by ultrafiltration were applied in coagulation tests under the same conditions as the crude extract, and the 4th fraction (molecules with molecular weights >30 kDa) with the predominant content of proteins with molecular weights 50 - 60 kDa, achieved almost as high efficiency of turbidity removal (75 %) as the crude extract. At the same time, the content of organic matter in treated water increased just for 16 % in comparison to the blank (model water processed in the same way but without coagulant). After optimization of process parameters by RSM for usage of the 4th fraction, the coagulation activity increased further to 80 %.
