“…This line of research may eventually be used to increase rubber production through genetic modification. Moreover, some molecules derived from acetyl-CoA (like polyester polyhydroxybutyrate) have a high industrial value in the pharmaceutical and chemical industries (Mazur et al, 2009;Xing et al, 2014), and controlling carbon flux through acetyl-CoA is an important topic for many biotechnology applications (Balcke et al, 2017). This study shows that there is a close relationship between ROS balance, fatty acid metabolism, and tapetum PCD, which lays a theoretical foundation for further research on the complex tapetum development process.…”

In flowering plants, the tapetum cells in anthers undergo programmed cell death (PCD) at the late meiotic stage, providing nutrients for further development of microspores, including the formation of the pollen wall. However, the molecular basis of tapetum PCD remains elusive. Here we report a tapetum PCD-related mutant in rice (Oryza sativa), earlier degraded tapetum 1 (edt1), that shows complete pollen abortion associated with earlier-than-programmed tapetum cell death. EDT1 encodes a subunit of ATP-citrate lyase (ACL), and is specifically expressed in the tapetum of anthers. EDT1 localized in both the nucleus and the cytoplasm as observed in rice protoplast transient assays. We demonstrated that the A and B subunits of ACL interacted with each other and might function as a heteromultimer in the cytoplasm. EDT1 catalyzes the critical steps in cytosolic acetyl-CoA synthesis. Our data indicated a decrease in ATP level, energy charge, and fatty acid content in mutant edt1 anthers. In addition, the genes encoding secretory proteases or lipid transporters, and the transcription factors known to regulate PCD, were downregulated. Our results demonstrate that the timing of tapetum PCD must be tightly regulated for successful pollen development, and that EDT1 is involved in the tapetum PCD process. This study furthers our understanding of the molecular basis of pollen fertility and fecundity in rice and may also be relevant to other flowering plants.

“…The use of PHA as a constituent in conventional synthetic plastic has been compromised because of its current high production cost (Bucci et al 2005;Chen et al 2001), stimulating the search for cheap carbon sources and nutritional supplements in order to lower costs (Albuquerque et al 2007;Mazur et al 2009). In this study, we selected different industrial wastes as media to minimize PHA production cost, and report a novel approach for small-scale PHA production.…”

“…According to Mazur et al (2009), bacteria from this genus are able to use biodiesel as a carbon source and are also known to produce a high content of extracellular polymeric material (EPS). These bacteria have been found in biodiesel produced from different raw materials (cottonseed oil and soybean oil).…”
