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. -

This paper reports the recent developments in the applications of the freshwater rotifers {Brachionus calyciflorus), Artemia nauplii, decapsulatedArtemia cysts and on-grown Artemia in the freshwater ornamental fish culture. Results demonstrate that the rotifers are an ideal starter feed for dwarf gourami {Colisa lalia), a typical freshwater ornamental fish species with larvae that are too small to ingest Artemia nauplii or Moina at its first feeding. Compared with the conventional yolk food, the use of rotifers as a starter feed significantly improves the growth and survival of the gourami larvae (Days 2-12), and the beneficial effects are extended to the subsequent Artemia-feeding phase (Days 13-32). The freshwater rotifers and Artemia nauplii are also useful in raising Discus larvae in the absence of their parents, which would eliminate the risk of larvae being eaten by the parent fish. -

This has also reportedly affected the payments from China to our exporters. The shortage of containers adds to the worries of the exporters to ship out seafood cargo from India to different destinations anticipating New Year demand. The General Administration and Customs China (GACC) has demanded a virtual inspection of two seafood processing units in India during the month and accordingly, two units were presented for virtual inspection by the end of the month to GACC on their preparedness on food safety, especially in tackling the Covid-19 contamination through seafood cargo.
