Callus, Dedifferentiation, Totipotency, Somatic Embryogenesis: What These Terms Mean in the Era of Molecular Plant Biology?

Frontiers in Plant Science, 2019
Recent findings call for the critical overview of some incorrectly used plant cell and tissue culture terminology such as dedifferentiation, callus, totipotency, and somatic embryogenesis.

Techniques for RNA in vivo imaging in plants [PDF]

, 2014
Since the discovery of small RNAs and RNA silencing, RNA biology has taken a centre stage in cell and developmental biology. Small RNAs, but also mRNAs and other types of cellular and viral RNAs are processed at specific subcellular localizations.

TOR senses and regulates spermidine metabolism during seedling establishment and growth in maize and Arabidopsis

iScience, 2021
Summary: Spermidine (Spd) is a nitrogen sink and signaling molecule that plays pivotal roles in eukaryotic cell growth and must be finetuned to meet various energy demands. In eukaryotes, target of rapamycin (TOR) is a central nutrient sensor, especially

Detection of leaf structures in close-range hyperspectral images using morphological fusion

Geo-spatial Information Science, 2017
Close-range hyperspectral images are a promising source of information in plant biology, in particular, for in vivo study of physiological changes. In this study, we investigate how data fusion can improve the detection of leaf elements by combining ...

Regulation of hierarchical carbon substrate utilization, nitrogen fixation, and root colonization by the Hfq/Crc/CrcZY genes in Pseudomonas stutzeri

iScience, 2022
Summary: Bacteria of the genus Pseudomonas consume preferred carbon substrates in nearly reverse order to that of enterobacteria, and this process is controlled by RNA-binding translational repressors and regulatory ncRNA antagonists.

DNA Topoisomerase 1α Promotes Transcriptional Silencing of Transposable Elements through DNA Methylation and Histone Lysine 9 Dimethylation in Arabidopsis [PDF]

, 2014
RNA-directed DNA methylation (RdDM) and histone H3K9 dimethylation (H3K9me2) are related transcriptional silencing mechanisms that target transposable elements (TEs) and repeats to maintain genome stability in plants.

Plant Biology: Bending of Plant Organs [PDF]

Current Biology, 2020
Tissue folding allows for the development of complex three-dimensional morphologies necessary for various functions. A new study provides novel mechanistic insights linking plant cell wall and hormonal pathways involved in bending of plant tissue through regulation of differential growth.
