Plant Signalling

Plant signalling is the way plants communicate with their environment and with other plants. It involves the transmission of messages through hormones and other chemical signals to control growth, development, and responses to environmental changes. Hormones play a major role in plant signalling, and they can be found in both plant tissues and in the environment. Auxins, gibberellins, and cytokinins are the three main types of hormones involved in plant signalling, and they are responsible for a variety of processes, including root growth, phototropism, and flowering. Other chemical signals, such as calcium, ethylene, and nitric oxide, also play an important role in plant signalling. These signals are transmitted both within individual plants and between plants, allowing them to respond to and coordinate with their environment. Plant signalling is essential for the survival of plants, and it is also increasingly being studied for its potential applications in agriculture and biotechnology.
