  • Hibiscus cannabinus, Cassia fistula and Abutilon indicum are medicinally important plants in India. Tissue culture studies have done for efficient propagation and for crop improvement in these three plants. Various explants were tried for callus induction, somatic embryogenesis and organagenesis with manipulation in culture media. Calli and somatic embryos were induced from hypocotyl explants in Hibiscus cannabinus, while in Cassia fistula and Abutilon indicum it could be obtained from leaf explants.

  • Light exerts two primary roles in plant growth and development. Plants acquire all biochemical energy required for growth and propagation solely from light energy via photosynthesis. In addition, light serves as a medium through which plants recognize environmental fluctuations, such as photoperiod and presence of neighboring animals and plants. Plants therefore constantly monitor the direction, intensity, duration, and wavelength of environmental light and integrate these light signals into the intrinsic regulatory programs to achieve an optimized growth in a given light condition. Although light regulates all aspects of plant growth and developmental aspects, the molecular mechanisms and signaling cascades involved have not been well established until recently. However, recent advances in genetic tools and plant transformation techniques greatly facilitated the elucidation of molecular events in plant photomorphogenesis. This mini-review summarizes the gist of recent findings in deetiolation and suppression of shade avoidance response as classic examples of the phytochrome-mediated photomorphogenesis.
