Auxin, one of the first identified and most widely studied phytohormones, has been and will
remain a hot topic in plant biology. After more than a century of passionate exploration, the …

The major natural auxin in plants, indole-3-acetic acid (IAA), orchestrates a plethora of
developmental responses that largely depend on the formation of auxin concentration …

It has been a dominant dogma in plant biology that the self-organizing polar auxin transport
system is necessary and sufficient to generate auxin maxima and minima that are essential …

The dominance of flowering plants on earth is owed largely to the evolution of maternal
tissues such as fruit and seedcoat that protect and disseminate the seeds. The mechanism …

In angiosperms, double fertilization triggers the concomitant development of two closely
juxtaposed tissues, the embryo and the endosperm. Successful seed development and …

The cereal endosperm is a major factor determining seed size and shape. However, the
molecular mechanisms of endosperm development are not fully understood. Long …

Genomic imprinting is an epigenetic phenomenon leading to parentally biased gene
expression. Throughout the years, extensive efforts have been made to characterize the …

Apomixis is a form of reproduction leading to clonal seeds and offspring that are genetically
identical to the maternal plant. While apomixis naturally occurs in hundreds of plant species …

The angiosperm seed is composed of three genetically distinct tissues: the diploid embryo
that originates from the fertilized egg cell, the triploid endosperm that is produced from the …

In flowering plants, seed development is initiated by the fusion of the maternal egg and
central cells with two paternal sperm cells, leading to the formation of embryo and …
