The essential micronutrients for field crops are B, Cu, Fe, Mn, Mo, and Zn. Other mineral nutrients at low concentrations considered essential to growth of some plants are Ni and Co. The incidence of micronutrient deficiencies in crops has increased markedly in recent years due to intensive cropping, loss of top soil by erosion, losses of micronutrients through leaching, liming of acid soils, decreased proportions of farmyard manure compared to chemical fertilizers, increased purity of chemical fertilizers, and use of marginal lands for crop production. Micronutrient deficiency problems are also aggravated by the high demand of modern crop cultivars. Increases in crop yields from application of micronutrients have been reported in many parts of the world. Factors such as pH, redox potential, biological activity, SOM, cation-exchange capacity, and clay contents are important in determining the availability of micronutrients in soils. Plant factors such as root and root hair morphology (length, density, surface area), root-induced changes (secretion of H+, OH−, HCO3−), root exudation of organic acids (citric, malic, tartaric, oxalic, phenolic), sugars, and nonproteinogenic amino acids (phytosiderophores), secretion of enzymes (phosphatases), plant demand, plant species/cultivars, and microbial associations (enhanced CO2 production, rhizobia, mycorrhizae, rhizobacteria) have profound influences on plant ability to absorb and utilize micronutrients from soil. The objectives of this article are to report advances in research on the micronutrient availability and requirements for crops, in correcting deficiencies and toxicities in soils and plants, and in increasing the ability of plants to acquire needed amounts of micronutrient elements.

Um dos maiores problemas fitossanitários da cultura do feijoeiro-comum (Phaseolus vulgaris L.) é a incidência de viroses transmitidas pela mosca branca, Bemisia tabaci, que reduzem significativamente a produtividade. Recentemente, a Embrapa desenvolveu a segunda geração de linhagens transgênicas de feijão, resistentes ao Bean golden mosaic virus (BGMV) por transgenia e ao Cowpea mild mottle virus (CPMMV) e ao BGMV por métodos tradicionais. Para validar a eficiência da linhagem CNFCT 19120, foi avaliada como fonte de inóculo do CPMMV, tendo como controle uma cultivar tolerante, BRS Sublime, e uma suscetível, BRSFC 401 RMD. |
