Growth at the shoot apical meristem (SAM) is essential for shoot architecture construction. The phytohormones gibberellins (GA) play a pivotal role in coordinating plant growth, but their role in the SAM remains mostly unknown. Here, we developed a ratiometric GA signaling biosensor by engineering one of the DELLA proteins, to suppress its master regulatory function in GA transcriptional responses while preserving its degradation upon GA sensing.

Introduction: Fast and accurate diagnosis of acute stroke is crucial to timely initiate reperfusion therapies. Conventional high-field (HF) MRI yields the highest accuracy in discriminating early ischaemia from haemorrhages and mimics. Rapid access to HF-MRI is often limited by contraindications or unavailability.

Article Synopsis
  • - ANT3310 is a new drug being tested alongside meropenem (MEM) to treat serious infections caused by drug-resistant bacteria, specifically carbapenem-resistant Gram-negative pathogens.
  • - In tests with 905 clinical bacterial isolates, the combination of MEM and ANT3310 showed significantly better antibacterial activity, reducing MIC values for carbapenem-resistant Enterobacterales from over 32 µg/mL to much lower levels.
  • - The combination of MEM and ANT3310 effectively inhibited the growth of nearly all tested resistant strains and proved effective in mouse models of thigh and lung infections, showing promise as a treatment option compared to other existing drug combinations.

Pseudomonas aeruginosa is a common pathogen in cystic fibrosis (CF) patients and a major contributor to progressive lung damage. P. aeruginosa elastase (LasB), a key virulence factor, has been identified as a potential target for anti-virulence therapy.

The plant hormone gibberellin (GA) regulates multiple developmental processes. It accumulates in the root elongating endodermis, but how it moves into this cell file and the significance of this accumulation are unclear. Here we identify three NITRATE TRANSPORTER1/PEPTIDE TRANSPORTER (NPF) transporters required for GA and abscisic acid (ABA) translocation.
