Developmental Biology - Root and Shoot Growth

In this free online course, learn about the developments of the root and shoot organs for mature plant growth.

Publisher: NPTEL
This free online course introduces you to the two distinct parts of the sessile nature of plants namely roots and shoots. You will be taught how the vascular tissues facilitate the transportation of water, minerals, and food throughout the plant. Further, the progression of the shoot system in plants through several discrete phases during its development and the developmental change in a plant's life cycle is also discussed.

This free online course introduces you to the process of initiation and development of the roots and shoot systems in plants. Discover the major steps that need to take place during the process of root development and how the establishment of the root apical meristem is dependent on the specification of a stem cell niche and the subsequent development of the quiescent centre at the presumptive root pole. The regulation of the transcription factors involved in root apical meristem and stem cell maintenance will be uncovered. Explore how asymmetric cell division, produces two daughter cells with different cellular fates and how the cortex-endodermis initial cell generates the two ground tissues. This will include the role of transcription factors in contributing to the sequential development of vascular tissues in plants. Investigate how the xylem and phloem tissues occur together in vascular bundles in all the organs of the plant and the role of vascular tissues in facilitating the transportation of water, minerals and food throughout the plant.

Next, the course goes on to explain the concept of root branching with an emphasis on lateral root development in plants. You will notice how auxin signalling regulates lateral root development through the transcriptional regulation of the key components involved in the developmental process. In addition to this, you will be taught how the shoot apical meristem generates above-ground aerial organs throughout the lifespan of higher plants. This will include the role of the shoot apical meristem in maintaining its meristematic property throughout the life of a plant. Unearth how organogenesis is the result of organ formation through dedifferentiation of differentiated cells and reorganization of cell division to create a particular organ. The process of deriving the lateral organs of the plants from the flanks of apical meristems and their inherent positional relationship will be brought to life. You will investigate how the leaves grow by distinct phases that are controlled by the gene regulatory networks including many transcription factors. 

Finally, you will learn about the developmental changes in a plant's life cycle that is marked by the floral transition. You will be taught how a photoreceptor may regulate flowering time in response to different photoperiods through its regulation of the circadian clock. You will come across different types of genes that participate in the specification of floral organ identity in plants. Would you like to learn how plant cells communicate to coordinate their activities in response to the changing conditions of light, dark, and temperature that guides their cycle of growth?  Would you like to understand how plasmodesmata interconnect cells and form an intercellular communication network within a plant body? This course explains these concepts and teaches you basic lab techniques that are used in the study of plant developmental biology. You will investigate the biological and physical methods of transforming explants to regenerate calluses. This Developmental Biology - Root and Shoot Growth, is an informative course, which will interest those studying plant Sciences, botany, biotechnology, agriculture or those who have an interest in these topics. Why wait? Sign up today and start learning about the fascinating science behind the growth of roots and shoots in the plant structure!
