Abiotic stress–plant interactions: morphoanatomical features and physiological functions
(Academic Press (Elsevier), 2026) Deepti Srivastava, P. Smriti Rao, Sandeep Kumar Singh, Deepak Kumar, Md Shamim, Kumari Vandna, Md Abu Nayyer, Saba Siddiqui, Mohammed Haris Siddiqui
Abiotic stress, an environmental condition that inhibits plant development, has traditionally been the focus of scientists and agronomists due to the constantly rising human populations, threatening food security. The morphophysiological and anatomical traits of plants are adversely impacted by several abiotic factors such as salt, heavy metal stress, drought, flooding, and extreme temperatures, leading to substantial yield losses of food crops. Globally, up to 90% of arable land is susceptible to one or more of the stresses, resulting in yield losses of up to 70% in major cereal crops such as rice, wheat, and maize and is expected to be even serious due to climate change. Understanding the impact of abiotic stresses on the intricate relationships between abiotic stressors and plants, emphasizing the vital morphoanatomical traits and physiological processes, will be crucial for developing plants to endure and adjust to harsh environmental conditions. Here, valuable insights into various plant adaptation strategies, enabling the development of healthy agricultural systems under abiotic stress to fulfill human food demands, are discussed.
COMBATING BULK AND NANO METAL TOXICITY USING CYANOBACTERIA
(Aargon Press, New Delhi, 2021) Zairish Imran , Reena Vishvakarma
Heavy metal toxicity in the ecosystem is a major environmental concern which needs urgent preventive and combating measures. A very common organism found in the aquatic ecosystem is cyanobacterium that tends to accumulate the heavy metals in polluted water bodies. Cyanobacteria ingests the heavy metal ions and either detoxify or metabolize the beavy metals, thus reduce the toxicity from the environment as well as act as a bioindicator to assess the chemical risk to the ecosystem. Cyanobacteria are well adapted to environmental stress conditions and have a robust antioxidant mechanism to fight any reactive oxygen species (ROS) generated due to the biotic or abiotic stress that cause cytotoxicity and oxidative damage. Transcriptome and proteome study of cyanobacteria involved in combating heavy metal toxicity reveals that stress induced proteins are generated that help the organism to adapt to the stress condition. A better understanding of the mechanism employed by cyanobacteria to combat metal toxicity can be delineated through more detailed molecular level study.
