Abstract:

Developmental patterning-such as longitudinal zonation of roots in growth domains, the transversal subdivision into layers of distinct cell types, and asymmetric growth during tropisms-is inherently multiscale and multiprocess. Consequently, computational models integrating these processes and scales are powerful tools to test whether our current understanding of involved players is both necessary and sufficient. Additionally, models help identify missing factors and reveal how the whole exceeds the sum of its parts. In this review, we discuss influential models that have advanced our understanding of root development and its adaptation to environmental conditions. We also highlight the potential for further integration of growth, mechanics, physiology, and physicochemical processes in these models. Such expansions are critical to advance the explanatory power of current models beyond genetic causes and identify the importance of cell size, nutrients, forces, pH, and ionic charge for developmental processes.

Water and Mineral Acquisition

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Primary and Secondary Growth in Roots and Shoots

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
