Chloroplasts in plant cells show active glassy behavior under low light conditions [PDF]

, 2022
Plants have developed intricate mechanisms to adapt to changing light conditions. Besides photo- and helio- tropism -- the differential growth towards light and the diurnal motion with respect to sunlight -- chloroplast motion acts as a fast mechanism to change the intracellular structure of leaf cells.

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores

Applications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

An isoform of the plastid RNA polymerase-associated protein FSD3 negatively regulates chloroplast development

BMC Plant Biology, 2019
Background Plastid-encoded RNA polymerase (PEP) plays an essential role in chloroplast development by governing the expression of genes involved in photosynthesis. At least 12 PEP-associated proteins (PAPs), including FSD3/PAP4, regulate PEP activity and

Identification and Phenotypic Characterization of ZEBRA LEAF16 Encoding a β-Hydroxyacyl-ACP Dehydratase in Rice

Frontiers in Plant Science, 2018
The chloroplast is a self-independent organelle and contains its own transcription and translation systems. The establishment of genetic systems is vital for normal plant growth and development. We isolated a rice zebra leaf 16 (zl16) mutant derived from

The Diverse Modes of Oxygen Reactivity in Life & Chemistry

ChemSusChem, Volume 15, Issue 24, December 20, 2022., 2022
Breath of life: Oxygen is the quintessential molecule of life on our planet. Three molecular oxygen species dominate natural and artificial oxygenation reactions: the singlet and triplet spin states of dioxygen and ozone. This Review summarizes key applications of these molecular oxygen species in biology, medicine, technologies, and laboratories ...

A shared mucosal gut microbiota signature in primary sclerosing cholangitis before and after liver transplantation

Hepatology, EarlyView., 2022
In this study of the gut mucosal microbiota in primary sclerosing cholangitis (PSC), we found consistent microbiota features associated with PSC and recurrent PSC, PSC with inflammatory bowel disease and a persistent gut dysbiosis after liver transplantation Abstract Background and Aims Several characteristic features of the fecal microbiota have been ...

Characterization and Fine Mapping of a Yellow-Virescent Gene Regulating Chlorophyll Biosynthesis and Early Stage Chloroplast Development in Brassica napus

G3: Genes, Genomes, Genetics, 2020
Chlorophyll biosynthesis and chloroplast development are crucial to photosynthesis and plant growth, but their regulatory mechanism remains elusive in many crop species.

Planktonic microbial communities from microbialite‐bearing lakes sampled along a salinity‐alkalinity gradient

Limnology and Oceanography, Volume 67, Issue 12, Page 2718-2733, December 2022., 2022
Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.
