IntroductionAbiotic stress is a global agricultural issue that limits plant growth and yield. Amongst abiotic stresses, salt stress leads to significant crop losses worldwide (Greenway and Munns, 1980). Although natural salts are present in soil, their increased concentration affects plant growth adversely. Rao et al. (2008) reported that salinity affects about 932 million hectares of land globally. In plant cells under salt stress, Na + and Clions accumulate in cytoplasm and lower the external water potential, resulting in turgor loss (Binzel et al., 1988). It creates an imbalance of cellular ions that results in ion toxicity, or osmotic stress, followed by significant oxidative stress (Gosset et al., 1996;Goemez et al., 1999;Hasegawa et al., 2000). Together, these factors lead to decreased plant growth, development, and survival. Elevated amounts of reactive oxygen species (ROS) such as superoxide (O 2•ˉ) , hydrogen peroxide (H 2 O 2 ), and hydroxyl (OH • ) radicals can critically disturb cellular homeostasis and standard metabolism through oxidative damage to protein, lipids, and nucleic acid (Baxter et al., 2007).Plants elicit a molecular response to prevent oxidative damage due to ROS production and adjust to the oxidative stress (Baxter et al., 2007;Demirkaya, 2014;Yaycılı and Alikamanoğlu, 2012). They have developed a multifaceted antioxidant defense with enzymatic molecules, including ascorbate peroxidase (APX, EC 1.11.1.11), glutathione reductase (GR, E.C. 1.6.4.2), and peroxidase (POD, EC 1.11.1.7). All these molecules play an important role in scavenging ROS formed during oxidative damage (Erdal and Çakırlar, 2014;Petrić et al., 2014).Recently, the role of heme oxygenase (HO, EC 1.14.99.3) has been recognized among plant defenses as a catalyst for the oxidation of heme to biliverdin IXα (BV), CO, and

“…One of the three known mammalian isoforms, heme oxygenase-1 (HO-1), is induced in animal tissues by many factors including its own substrate heme, heavy metals, UV-A radiation among others (Tomaro & Batlle 2002). While earlier studies pointed to plant HO as a source of phytochrome chromophore , more recent works showed that HO synthesis increases in soybean plants subjected to oxidative stress conferring resistance to a subsequent insult (Noriega et al 2004;Balestrasse et al 2005). Moreover, we have recently demonstrated that ROS are involved in HO-1 upregulation in soybean leaves subjected to UV-B radiation (Yannarelli et al 2006 andSanta Cruz et al 2010).…”

Bilins are open‐chain tetrapyrroles with a wide range of visible and nearly visible‐light absorption and emission properties. The linear tetrapyrrole molecules function as chromophores of the light‐harvesting phycobiliproteins and phytochrome‐mediated light sensing in photosynthetic organisms. They are derived from the cyclic precursor haem. The initial step in bilin biosynthesis is the conversion of haem into biliverdin (BV IX α) catalysed by haem oxygenase, which is subsequently reduced to specific bilins by ferredoxin‐dependent bilin reductases (FDBRs). Bilins usually bound to apoproteins via single or double covalent bonds to form a macromolecular complex phycobilisomes. The attachment of apoproteins to bilin is an autocatalytic process, but bilin lyases are required for the specific attachment of bilin chromophores to phycobiliprotein apoproteins. Besides the biosynthesis, structure and functions of bilins, this article also aims to recapitulate and discuss the current progress in the field of bilins and to emphasise the emerging areas. Key Concepts Bilins are open‐chain tetrapyrrole non‐metallic colour compounds formed as a metabolic product of protoporphyrin IX. Biliverdin IX α is the common precursor of all naturally occurring bilins. Haem oxygenase (HO) and ferredoxin‐dependent bilin reductases (FDBRs) are the two key enzymes involved in the biosynthesis of bilins. Phycobiliproteins assemble with bilins to form phycobilisomes, which help in light harvesting and energy transfer. Bilin plays a significant role in various physiological processes, namely, photosynthesis, respiration, light perception, signalling, cell defence against oxidative stress, nitrate and sulfate assimilation and programmed cell death.
