“…Under FR-D light, TMX treatment did not affect stem length of soybean plants (Table 1). This is inconsistent with the study of Triticum aestivum L. (wheat), where TMX treatment induced a significant increase in stem length (Perelló and Dal Bello 2011). Differential metabolism of TMX into a compound, which can trigger stem elongation in wheat, may provide an explanation for the disparate effect of TMX on stem length in soybean and wheat.…”

“…It is then significant that the growth stimulatory effects of TMX on several plants (Cataneo et al 2010;Macedo and Castro 2011;Perelló and Dal Bello 2011;Almeida et al 2012;Macedo et al 2013b;Almeida et al 2014) are to some extent comparable to the growth stimulatory effects of SA (Gutiérrez-Coronado et al 1998;Shakirova et al 2003;Gunes et al 2007;RivasSan Vicente and Plasencia 2011). Given that both the SAand JA signaling pathways are repressed under FR-E light (Cerrudo et al 2012, de Wit et al 2013, one would expect that the TMX treatment at least in part derepress the SA signaling pathway.…”

Changes in light quality alter physiological responses of soybean to thiamethoxam

The interaction between neighboring weed-induced far-red enriched light and thiamethoxam can significantly alter soybean seedling morphology, nodulation, isoflavone levels, UV-absorbing phenolics, and carbon and nitrogen content. Neonicotinoid insecticides that are widely used on major crop plants can enhance plant growth and yield. Although the underlying mechanism of this enhanced growth and yield is not clear, recent studies suggest that neonicotinoids such as thiamethoxam (TMX) may exert their effects at least in part via signals that involve salicylic acid (SA) and jasmonic acid (JA). In the current research, effects of TMX on morphological and physiological responses of soybean have been compared under far-red-depleted (FR-D) and far-red-enriched (FR-E) light reflected by neighboring weeds. TMX significantly enhanced shoot and root growth but did not prevent stem elongation under FR-E light. Also, TMX did not prevent reductions in shoot carbon content and shoot carbon to nitrogen ratio under FR-E light. Despite similarities between these TMX effects in soybean and those known for SA and JA in other plant species, TMX significantly enhanced root-nodule numbers per plant and levels of root isoflavones malonyl-daidzin and malonyl-genistin under FR-E light only. These results suggest that the combined effect of FR-E light and TMX triggers a mechanism that operates concomitantly to enhance root isoflavones and nodulation in soybean.

Microbial inoculation of seed for improved crop performance: issues and opportunities

There is increasing interest in the use of beneficial microorganisms as alternatives to chemical pesticides and synthetic fertilisers in agricultural production. Application of beneficial microorganisms to seeds is an efficient mechanism for placement of microbial inocula into soil where they will be well positioned to colonise seedling roots and protect against soil-borne diseases and pests. However, despite the long history of inoculation of legume seeds with Rhizobia spp. and clear laboratory demonstration of the ability of a wide range of other beneficial microorganisms to improve crop performance, there are still very few commercially available microbial seed inoculants. Seed inoculation techniques used for research purposes are often not feasible at a commercial scale and there are significant technical challenges in maintaining viable microbial inocula on seed throughout commercial seed treatment processes and storage. Further research is needed before the benefits of a wide range of environmentally sensitive potential seed inoculants can be captured for use in agriculture, ecosystem restoration and bioremediation. There is no single solution to the challenge of improving the ability of seed inoculants to establish and function consistently in the field. Development of novel formulations that maintain the viability of both inoculant and seed during storage will result from multidisciplinary research in microbial and seed physiology and adjuvant chemistry.
