RNA-binding proteins (RBPs) are central components of gene regulatory networks. The differentiation of heterocysts in filamentous cyanobacteria is an example of cell differentiation in prokaryotes. Although multiple non-coding transcripts are involved in this process, no RBPs have been implicated thus far.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia, Universitat Autònoma de Barcelona, 08193, Bellaterra, Barcelona, Spain; Association for the Study and Conservation of Elasmobranchs and its Ecosystems (Catsharks), Barcelona, Spain.
Article Synopsis
- Plastic pollution is a significant threat to marine ecosystems, and recent research on the small-spotted catshark reveals that these sharks are using plastic debris for laying eggs when traditional substrates are lacking.
- This behavior change is influenced by factors like pollution, habitat degradation, and fishing pressure, indicating a concerning shift in their nesting habits due to environmental pressures.
- As plastic debris increases and natural habitats decline, understanding the impact on the catshark's fitness and survival is crucial, emphasizing the importance of protecting natural marine habitats.

, the putative wild ancestor of quinoa, is a source of traits that could improve the tolerance of crop quinoa to high temperatures. However, seeds of have physiological dormancy (PD), which is an obstacle for plant propagation and use in breeding programs. We studied the intraspecific variability in morpho-anatomical traits of embryo covering structures and their association with PD.

L. (plantain) increases herbage dry matter (DM) production and quality during warm and dry conditions due to its deep roots and drought tolerance and reduces nitrogen losses in grazing systems compared to traditional pastures. However, plantain density usually declines after the third growing season, mainly due to defoliation management.

September 2024
The New Zealand Institute for Plant and Food Research Limited, Auckland 1025, New Zealand.
Article Synopsis
- Mycoviruses are diverse viruses that can alter the characteristics of their fungal hosts, but there is a lack of detailed research on them.
- The proposed model focuses on a specific fungus known for its ease of study, wide distribution, and existing research resources, making it a prime candidate for exploring mycovirus interactions.
- By studying mycoviruses in this model, researchers aim to gain valuable insights that could benefit understanding of plant pathogens and enhance knowledge of virus-fungal interactions.
