| Abstract | Plastome is thought to be a very conservative part of plant genome but little is known about the evolution of plastome promoters. It was previously shown that one light-regulated promoter (LRPpsbD) is highly conserved in different flowering plant species and in black pine. We have undertaken search and demonstrated that gene ndhF is located in a plastome region that rarely underwent substantial rearrangements in terrestrial plants. However, alignment of sequences upstream ndhF suggests that promoters of this gene underwent comparatively rapid evolution in flowering plants. Probably, the ancestor of two basal Magnoliophyta branches (magnoliids and eudicotyledons) had the promoter P$_{A}$-ndhF, which was substituted with other promoters—P$_{B}$-ndhF and P$_{C}$-ndhF—in some phylogenetic lineages of dicots. We failed to reveal conservative sequences with potential promoters of −10/−35 type upstream ndhF genes of monocotyledonous plants, including nine representatives of the grass family (Poaceae). Multiple alignments of sequences from related taxa showed that the predicted ndhF promoters (A–C) underwent frequent mutations and these mutations are not only nucleotide substitutions but also small insertions and deletions. Thus, we can assume that at least some plastome promoters evolve rapidly. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
