Flip the light switch for protein production

Protein synthesis, modification, and degradation are not only crucial for responding to environmental change, but they also represent significant energy costs for a plant. Energy homeostasis is highly affected by the presence of light. In young seedlings, light enhances translation during the dark-to-light transition, although we do not fully understand how this process is regulated. […]

Tailored protein stability for stress resilience in light and dark

Light influences essentially all aspects of plant growth and development. Furthermore, plants are likely to adjust their stress responses based on fluctuations in energy availability during the dark-light cycle. Lin et al investigated a hormone downstream component, ETHYLENE RESPONSE FACTOR 1 (ERF1), and discovered that its posttranslational modifications are coordinated by dark or light conditions. […]

Crossing the gap: Decrypting the genome facilitates gene identification in wild rice

Domesticated crops provide a reliable food source but generally have little genetic diversity to cope with environmental fluctuations. By decrypting the genome of wild species such as the wild rice Oryza rufipogon, we may identify additional genetic variation useful for breeding process. However, the genomic heterozygosity of wild species is very challenging to work with. […]

Translocation of a chloride channel from the Golgi to the plasma membrane helps plants adapt to salt stress

Plants adapt to salt stress by maintaining ion balance using ion transporters. While much is known about cation transporters, the role of anion transporters is less clear. Rajappa et al. focus on the chloride channel gene AtCLCf in Arabidopsis thaliana, controlled by the transcription factor WRKY9 under salt stress. Plants lacking AtCLCf are more sensitive […]

COP1 regulates salt tolerance via GIGANTEA degradation in roots

Global climate change affects weather patterns, and excess soil salinity harms plant growth. Previous studies have shown interaction between the circadian clock and salt responses. In normal conditions, the core circadian clock oscillator GIGANTEA (GI) sequesters the SOS2 kinase, part of the salt-overly sensitive (SOS) pathway. Salt stress triggers calcium signals that cause GI to […]

Coordinated wound responses in a regenerative animal-algal holobiont

Many animals such as corals and sea slugs host photosynthetic symbionts. Several studies have investigated how the host and symbiont coordinate their activities. This new study by Sarfati et al. explores how symbiotic green algae and their animal host, the flattened-worm Convolutriloba longifissura, respond to injury. When the animal is injured, the algae’s photosynthetic efficiency […]

A novel BZR/BES transcription factor controls the development of haploid reproductive organs in Marchantia polymorpha

Gametogenesis is essential for sexual reproduction. In bryophytes, lycophytes, and ferns, gametogenesis takes place in gametangia: antheridia for sperm production and archegonia for egg production. How these specialized reproductive organs develop at the molecular level remains unclear. Furuya et al. identified a unique BZR/BES transcription factor, MpBZR3, that regulates gametangium development in Marchantia polymorpha. Overexpression […]
