Understanding Plant Development

In this free online course, learn about the various approaches and techniques used to study plant development.

Publisher: NPTEL
This free online course introduces you to the development process of various tissues and organs from a single cell zygote in a complex multicellular plant. You will be taught about the various phases in the life cycle of an Angiosperm plant and the various developmental phases of plant architecture. The functional characterization process of the genes and the significance of gene interaction will be unveiled.

This free online course introduces you to a broad spectrum of processes in plant development. This includes the elaboration of a mature vegetative plant from the embryo to the mature plant. You will discover the development process of various tissues and organs from a single cell zygote in a complex multicellular plant. This incorporates how the different organs of a plant are developed during various phases of their life cycle, particularly of an Angiosperm plant and how the process of pollination results in the double fertilization and formation of seeds. The characteristic features of plant growth, where the meristematic activities are positioned, and how they are maintained and coordinated during the process of plant growth and development, will be uncovered. This encompasses how the primary, secondary and lateral growths and developmental processes together ensure proper plant architecture. You will discover the evolving developmental pattern of plants that are continuous, responsive to environmental cues, and regenerative. Alongside this, the process of attaining the developmental features by the exchange of the information between the cells that are local as well as long-range, are also discussed.

Next, the course goes on to explain how the cell fate in the developing region is more dependent on the positional cues compared to the lineage information. The Forward Genetics Approach for determining the genetic basis responsible for a phenotype will be introduced. Can you imagine being able to differentiate ways of generating and identifying a particular developmental mutant with a defect or with a phenotype? The process of analyzing the inheritance pattern, mapping the genetic locus and validating the association of a genotype and phenotype are resolved. You will notice how the forward genetics-based approaches are being practised for analyzing development in the case of plants. You will be taught about the process of identifying single genes with putative developmental function, and genome-wide genes for developmental processes. This will include the method of identifying and isolating the gene of interest in studying its developmental functions. Further, the process of studying the expression pattern for identifying the genes that are differentially expressed between two conditions or two organs are examined. You will investigate the means of analyzing the expression pattern of differential genes in different conditions.

Understanding the spatial and temporal expression pattern analysis of a gene in plants will complete this course. You will explore the techniques used for localization and detection of specific DNA and RNA sequences in cells and a gene trap strategy for the discovery of specific cell-type markers. This will involve the activation of genes within specific tissues of an organism at specific times during development. The approaches for investigating the gene function and its physiological significance by systematically knocking-out genes one by one through disrupting the function using insertional mutagenesis are underlined. Methods of generating dominant mutations in plant cells by random insertion of a T-DNA carrying constitutive enhancer elements will be explained. You will notice how two genes produce a phenotype in light of each mutation's individual effects by revealing the functional relationships between genes and pathways. Understanding Plant Development is an informative course, which will interest those studying plant sciences, botany, biotechnology, agriculture or those who have an interest in these topics.
