The NAM-B1 gene is a NAC transcription factor that affects grain nutrient concentrations in wheat (Triticum aestivum). An RNAi line with reduced expression of NAM genes has lower grain protein, iron (Fe), and zinc (Zn) concentrations. To determine whether decreased remobilization, lower plant uptake, or decreased partitioning to grain are responsible for this phenotype, mineral dynamics were qu...

The use of organic waste for the production plant substrates is an important environmental and economic alternative. In this perspective, we performed a work in greenhouse, with aim evaluating effect from during growth, gas exchange accumulation mineral elements ‘Sunrise Solo’ papaya tree seedlings. experimental design adopted was completely randomized, four treatments five repetitions, six pla...

s Cadmium (Cd) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients. Plant nutrients and Cd compete for the same transport-ers and, therefore, presence of Cd results i...

BACKGROUND AND AIMS Mediterranean woody plants have a wide variety of phenological strategies. Some authors have classified the Mediterranean phanaerophytes into two broad phenological categories: phenophase-overlappers (that overlap resource-demanding activities in a short period of the year) and phenophase-sequencers (that protract resource-demanding activities throughout the year). In this w...
