Los cereales son los cultivos agrícolas más importantes del mundo. La producción toral de los ocho tipos más abundantes (trigo, maíz, arroz, cebada, sorgo, avena, mijo y centeno, en orden decreciente de importancia) excede de 1600 millones de toneladas métricas (según datos de la FAO, 1982). De ellos, la producción anual mundial de trigo es de...

Programmed cell death (PCD) is a process of organized destruction of cells, essential for the development and maintenance of cellular homeostasis of multicellular organisms. Cells undergoing PCD begin a degenerative process in response to internal or external signals, whereby the nucleus becomes one of the targets. The process of nuclear...

In photosynthetic plant cells, chloroplasts act as factories of metabolic intermediates that support plant growth. Chloroplast performance is highly influenced by environmental cues. Thus, these organelles have the additional function of sensing ever changing environmental conditions, thereby playing a key role in harmonizing the growth and...

The aleurone layer of cereal grains undergoes a gibberellin-regulated process of programmed cell death (PCD) following germination. We have applied a combination of ultrastructural and biochemical approaches to analyze aleurone PCD in intact wheat grains. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay revealed...
