Melatonin synthesis genes N-acetylserotonin methyltransferases evolved into caffeic acid O-methyltransferases and both assisted in plant terrestrialization.

J Pineal Res 2021 Apr 12:e12737. Epub 2021 Apr 12.

Department of Cell Systems and Anatomy, UT Health, Long School of Medicine, San Antonio, TX, USA.

Terrestrialization is one of the most momentous events in the history of plant life, which led to the subsequent evolution of plant diversity. The transition species, in this process, had to acquire a range of adaptive mechanisms to cope with the harsh features of terrestrial environments compared to that of an aquatic habitat. As an ancient antioxidant, a leading regulator of ROS signaling or homeostasis, and a presumed plant master regulator, melatonin likely assisted plants transition to land and their adaption to terrestrial ecosystems.

Identification and biochemical characterisation of tyrosine aminotransferase from Anthoceros agrestis unveils the conceivable entry point into rosmarinic acid biosynthesis in hornworts.

Planta 2021 Apr 12;253(5):98. Epub 2021 Apr 12.

Philipps-Universität Marburg, Institut für Pharmazeutische Biologie und Biotechnologie, Robert-Koch-Str. 4, 35037, Marburg, Germany.

Main Conclusion: Tyrosine aminotransferase (AaTAT) from the hornwort Anthoceros agrestis Paton (Anthocerotaceae) was amplified and expressed in E. coli. The active enzyme is able to accept a wide range of substrates with distinct preference for L-tyrosine, therefore, possibly catalysing the initial step in rosmarinic acid biosynthesis. Read More

Front Plant Sci 2021 26;12:644389. Epub 2021 Mar 26.

Key Laboratory of Forest Silviculture and Conservation of the Ministry of Education, The College of Forestry, Beijing Forestry University, Beijing, China.

Abel. is an important woody oil species; however, the shortage of rapid and industrialized seedling culture is a large constraint on the development of the tea oil industry. Somatic embryogenesis (SE) is one of the main powerful biotechnological tools for plant mass regeneration, but the largely unknown SE in limits the scale production of clonal plants. Read More

Liverwort flora of Ayan - a gained link between subarctic and hemiboreal floras in West Okhotiya (Pacific Russia).

Biodivers Data J 2021 1;9:e65199. Epub 2021 Apr 1.

Team of National Ecosystem Survey, National Institute of Ecology, Seocheon, South Korea Team of National Ecosystem Survey, National Institute of Ecology Seocheon South Korea.

The liverwort flora of Ayan was first investigated one hundred and fifty years after the first exploration of vascular plants. A number of factors has determined the relatively high taxonomic diversity of liverworts in this hemiarctic flora of small-sized area: 118 species and one subspecies were revealed. These data are new not only for the studied area, but also for the huge land adjacent to the western coast of the Sea of Okhotsk. Read More

Evolution of the Unfolded Protein Response in Plants.

Stephen H Howell

Plant Cell Environ 2021 Apr 10. Epub 2021 Apr 10.

Plant Sciences Institute and Genetics, Development and Cell Biology Department, Iowa State University, Ames, Iowa, US.

The Unfolded Protein Response (UPR) in plants is elicited by endoplasmic reticulum stress which can be brought about by adverse environmental conditions. The response is mediated by a conserved signaling network composed of two branches - one branch involving INOSITOL REQUIRING ENZYME1- BASIC LEUCINE ZIPPER60 (IRE1-bZIP60) signaling pathway and another branch involving the membrane transcription factors, bZIP17 and - 28. The UPR has been reported in Chlamydomonas reinhardtii, a unicellular green alga, which lacks some canonical UPR signaling components found in vascular plants, raising the question whether C.

HAG1 and SWI3A/B control of male germ line development in P. patens suggests conservation of epigenetic reproductive control across land plants.

Plant Reprod 2021 Apr 11. Epub 2021 Apr 11.

Plant Cell Biology, Department of Biology, University of Marburg, Marburg, Germany.

Key Message: Bryophytes as models to study the male germ line: loss-of-function mutants of epigenetic regulators HAG1 and SWI3a/b demonstrate conserved function in sexual reproduction. With the water-to-land transition, land plants evolved a peculiar haplodiplontic life cycle in which both the haploid gametophyte and the diploid sporophyte are multicellular. The switch between these phases was coined alternation of generations. Read More

The benzoate plant metabolite ethyl gallate prevents cellular- and vascular-lipid accumulation in experimental models of atherosclerosis.

Biochem Biophys Res Commun 2021 Apr 8;556:65-71. Epub 2021 Apr 8.

School of Chemistry and Chemical Engineering, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250353, China. Electronic address:

Ethyl gallate (EG) is a well-known constituent of medicinal plants, but its effects on atherosclerosis development are not clear. In the present study, the anti-atherosclerosis effects of EG and the underlying mechanisms were explored using macrophage cultures, zebrafish and apolipoprotein (apo) E deficient mice. Treatment of macrophages with EG (20 μM) enhanced cellular cholesterol efflux to HDL, and reduced net lipid accumulation in response to oxidized LDL. Read More

Acropetally developing vascular bundles coexisting with basipetally developing and basally blindly ended vascular bundles in scapes of Eriocaulon taquetii (Eriocaulaceae, monocotyledons).

J Plant Res 2021 Apr 9. Epub 2021 Apr 9.

, Karabe 4-26-38, Narita, 286-0036, Japan.

In various monocotyledons, there are basally blindly ended stem vascular bundles, which never connect to the vascular bundles of roots. These blindly ended vascular bundles seem to be unsuitable for transferring water in terrestrial plants. In the present study, we aim to clarify the trace of the blindly ended stem vascular bundles in whole plants, and consider the evolutional process for holding such vascular bundles in the stem.

Ancient noeggerathialean reveals the seed plant sister group diversified alongside the primary seed plant radiation.

Proc Natl Acad Sci U S A 2021 Mar 8;118(11). Epub 2021 Mar 8.

Indiana Geological and Water Survey, Bloomington, IN 47404;

Noeggerathiales are enigmatic plants that existed during Carboniferous and Permian times, ∼323 to 252 Mya. Although their morphology, diversity, and distribution are well known, their systematic affinity remained enigmatic because their anatomy was unknown. Here, we report from a 298-My-old volcanic ash deposit, an in situ, complete, anatomically preserved noeggerathialean. Read More

J Plant Res 2021 Apr 8. Epub 2021 Apr 8.

Institute of Experimental Biology, University of Wroclaw, Kanonia Str. 6/8, 50-328, Wrocław, Poland.

Phyllotactic diversity and developmental transitions between phyllotactic patterns are not fully understood. The plants studied so far, such as Magnolia, Torreya or Abies, are not suitable for experimental work, and the most popular model plant, Arabidopsis thaliana, does not show sufficient phyllotactic variability. It has been found that in common verbena (Verbena officinalis L. Read More
