Mitochondrial Genomes of the Early Land Plant Lineage
Dong et al. BMC Genomics (2019) 20:953 https://doi.org/10.1186/s12864-019-6365-y RESEARCH ARTICLE Open Access Mitochondrial genomes of the early land plant lineage liverworts (Marchantiophyta): conserved genome structure, and ongoing low frequency recombination Shanshan Dong1,2, Chaoxian Zhao1,3, Shouzhou Zhang1, Li Zhang1, Hong Wu2, Huan Liu4, Ruiliang Zhu3, Yu Jia5, Bernard Goffinet6 and Yang Liu1,4* Abstract Background: In contrast to the highly labile mitochondrial (mt) genomes of vascular plants, the architecture and composition of mt genomes within the main lineages of bryophytes appear stable and invariant. The available mt genomes of 18 liverwort accessions representing nine genera and five orders are syntenous except for Gymnomitrion concinnatum whose genome is characterized by two rearrangements. Here, we expanded the number of assembled liverwort mt genomes to 47, broadening the sampling to 31 genera and 10 orders spanning much of the phylogenetic breadth of liverworts to further test whether the evolution of the liverwort mitogenome is overall static. Results: Liverwort mt genomes range in size from 147 Kb in Jungermanniales (clade B) to 185 Kb in Marchantiopsida, mainly due to the size variation of intergenic spacers and number of introns. All newly assembled liverwort mt genomes hold a conserved set of genes, but vary considerably in their intron content. The loss of introns in liverwort mt genomes might be explained by localized retroprocessing events. Liverwort mt genomes are strictly syntenous in genome structure with no structural variant detected in our newly assembled mt genomes. However, by screening the paired-end reads, we do find rare cases of recombination, which means multiple concurrent genome structures may exist in the vegetative tissues of liverworts. -
A Compendium to Marchantiophyta and Anthocerotophyta of Assam, India
Marchantiophyta and Anthocerotophyta of Assam 1 A Compendium to Marchantiophyta and Anthocerotophyta of Assam, India S. K. Singh and H. A. Barbhuiya Botanical Survey of India, Eastern Regional Centre, Lower New Colony, Laitumkhrah, Shillong – 793003, India Correspondences: [email protected] Abstract. A catalogue of 107 species of liverworts (Marchantiophyta) and 8 species of hornworts (Anthocerotophyta), recorded from Assam, India is presented. This includes three new records for India viz., Cololejeunea denticulata (Horik.) S. Hatt., C. inflata Steph., Plagiochila furcifolia Mitt., and three species viz., Cololejeunea desciscens Steph. Colura ari (Steph.) Steph., Lopholejeunea eulopha (Taylor) Schiffn. new to mainland. Twelve species are new record for Eastern Himalayan bryo-geographical territory, 20 species as new to Assam and seven species are endemic to Indian regions. Introduction Marchantiophyta and Anthocerotophyta traditionally known as liverworts and hornworts (Bryophytes) are integral part of any ecosystems and recognized as land dwellers in plant kingdom. They are first colonizer of terrestrial habits after Algae and come after Lichens in plant succession. The taxonomic studies on these groups of plant are far from complete particularly in Indian region. Assam lies in rain shadow of Himalayan ranges and forms part of East Himalayan Bryo- geographical Territory. As far as studies on Marchantiophyta and Anthocerotophyta of the region are concerned, it was initiated by William Griffith in first half of of the nineteenth century who’s work was published in the form of posthumous papers finally culminated into ‘Notulae ad Plantas Asiaticas’ (Griffith, 1849a) wherein he reported many species of cryptogams from earstwhile undivided Assam including ca.18 liverworts of present day Assam. -

The Classification, Distribution, Control and Economic Importance of Aquatic Plants
International Journal of Fisheries and Aquatic Sciences 1(2): 118-128, 2012 ISSN: 2049-8411 E-ISSN: 2049-842X © Maxwell Scientific Organization, 2012 Submitted: May 15, 2012 Accepted: June 23, 2012 Published: October 20, 2012 The Classification, Distribution, Control and Economic Importance of Aquatic Plants A.A. Oyedeji and J.F.N. Abowei Department of Biological Sciences, Faculty of Science, Niger Delta University, Wilberforce Island, Nigeria Abstract: The study reviews the classification, distribution, control and economic importance of aquatic plants to provide fish culturist information on some future challenges in culture fisheries management and practices. Aquatic plants have adapted to living in or on aquatic environments and constitute a problem in culture fisheries. They block navigational channels on the waterways and easily choke the propellers of boats. Many fish keepers keep aquatic plants in their tanks to control phytoplankton and moss by removing metabolites. Many species of aquatic plant are invasive species. However, some aquatic constitute the primary producers of aquatic ecosystems. They convert incident radiant energy of the sun to chemical energy in the presence of nutrients like phosphorous, nitrogen, iron, manganese, molybdenum and zinc. They are the foundation of the food web, in providing a nutritional base for zooplankton and subsequently to other invertebrates, shell fish and finfish. The productivity of any water body is determined by the amount of aquatic plants it contains as they are the major primary and secondary producers; hence, can be use as bio indicators. The study provides information on the meaning of aquatic plants, types of aquatic plants, characteristics of hydrophytes, adaptations, zonation, classification and control of aquatic weeds to provide the required information for fish culturists. -

We are active all over the world in a variety of ways, whether it be on a Plantahunter tour in Florida or Borneo or on our partner farm in Sri Lanka. Constant contact with good friends in Japan, China, Taiwan and India helps us to develop new plant products. But one or two long „forgotten“ plants are also regaining significance. Modern aquascaping in particular has significantly enhanced awareness of the needs of plants. These days, plant enthusiasts with underwater gardens no longer ask whether or not CO2 fertilisation is necessary. In addition to many new plants in pots, we have expanded our selection of in-vitro plants and established a separate product segment. In the new plant-it series there are now 22 attractive plants for various planting areas in the aquarium. The plant-it tubs are especially well suited for aquascaping. Their small size means you can insert the plants into the hardscape between stones and roots very easily. There are also new and exciting things to discover in the decorative range. The range of products for designing magical underwater landscapes is supplemented by Bonsai Palm, Scape Wood, Coco Cave, Scaper pads and much more. …..now have fun „gardening“ under water!
