Cell walls are highly dynamic structures that provide mechanical support for plant cells
during growth, development and adaptation to a changing environment. Thus, it is important …

Plants produce organs of various shapes and sizes. While much has been learned about
genetic regulation of organogenesis, the integration of mechanics in the process is also …

Positional information is essential for coordinating the development of multicellular
organisms. In plants, positional information provided by the hormone auxin regulates …

As scientists, we are at least as excited about the open questions—the things we do not
know—as the discoveries. Here, we asked 15 experts to describe the most compelling open …

Substantial diversity exists for both the size and shape of the leaf, the main photosynthetic
organ of flowering plants. The two major forms of leaf are simple leaves, in which the leaf …

The root system is a major determinant of a plant's access to water and nutrients. The
architecture of the root system to a large extent depends on the repeated formation of new …

Brassinosteroids (BRs) participate in the regulation of plant growth and development
through BRI1-EMS-SUPPRESSOR1 (BES1)/BRASSINAZOLE-RESISTANT1 (BZR1) family …

Distinct from animals, plants maintain organogenesis from specialized tissues termed
meristems throughout life. In the shoot apex, the shoot apical meristem (SAM) produces all …

Morphogenesis is a highly controlled biological process that is crucial for organisms to
develop cells and organs of a particular shape. Plants have the remarkable ability to adapt …

Plants continuously produce lateral organs from the shoot apex such as leaves and flowers,
providing an excellent opportunity to study their development. The plant hormone auxin …
