On growth habits and forms: the utility of stem anatomy to define growth habits of Melastomataceae

Acta Botanica Mexicana, 2018
Background and Aims: The growth habit is a character commonly used in taxonomic descriptions of plants and one of the first to be taught to students of plant morphology. Defining growth habits has turned into a complex matter due to the proliferation of terms. By definition, some habits can be distinguished by plant stem anatomy, but there are actually

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Application of third-order nonlinear optical materials in complex crystalline chemical reactions of borates

Nonlinear Engineering, 2022
In order to explore the application of third-order nonlinear optical (NLO) materials in complex borate crystalline chemical reactions, the laser light source with limited wavelength range can be extended to ultraviolet (UV) and deep UV region by using ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Characterization of CcTFL1 Governing Plant Architecture in Pigeon pea (Cajanus cajan (L.) Millsp.)

Plants, 2023
Growth habits are among the essential adaptive traits acted upon by evolution during plant speciation. They have brought remarkable changes in the morphology and physiology of plants.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Diversity of metaxylem vessel elements in three Syagrus palms (Arecaceae) of different habits Diversidade dos elementos de vaso do metaxilema em três espécies de Syagrus (Arecaceae) de diferentes hábitos

Acta Botânica Brasílica, 2011
Vessel elements in Monocotyledons present morphological differences according to the organ where they occur. Usually such diff erences have been explained from an evolutionary perspective, with few data on how the vessel elements could be infl uenced by ...

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

FEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Allelic variations at the HvSNF2 and HvBM5 loci are associated with the heading date and growth habit of barley (Hordeum vulgare L.) under a semi-arid climate

Czech Journal of Genetics and Plant Breeding, 2021
The heading date and growth habit are key factors that regulate the transition from the vegetative to the reproductive stage in barley. In this study, we used PCR based markers to identify the allelic variations in the Vrn-H1 (HvMB5) and Vrn-H2 (HvSNF2 ...
