Background: There are numerous systems and techniques to measure the growth of plant roots. However, phenotyping large numbers of plant roots for breeding and genetic analyses remains challenging. One major difficulty is to achieve high throughput and resolution at a reasonable cost per plant sample. Here we describe a cost-effective root phenotyping pipeline, on which we perform time and accuracy benchmarking to identify bottlenecks in such pipelines and strategies for their acceleration.
Results: Our root phenotyping pipeline was assembled with custom software and low cost material and equipment. Results show that sample preparation and handling of samples during screening are the most time consuming task in root phenotyping. Algorithms can be used to speed up the extraction of root traits from image data, but when applied to large numbers of images, there is a trade-off between time of processing the data and errors contained in the database.
Conclusions: Scaling-up root phenotyping to large numbers of genotypes will require not only automation of sample preparation and sample handling, but also efficient algorithms for error detection for more reliable replacement of manual interventions.

The stimulator of interferon genes (STING) pathway represents a promising target in cancer immunotherapy. However, the clinical translation of cyclic dinucleotide (CDN)-based STING agonists remains hindered by insufficient formation of functional CDN-STING complexes. This critical bottleneck arises from two interdependent barriers: inefficient cytosolic CDN delivery and tumor-specific STING silencing via DNA methyltransferase-mediated promoter hypermethylation.

Objectives: Loeys-Dietz syndrome comprises genetically discrete subtypes of varying clinical severity. This study integrates longitudinal Loeys-Dietz syndrome clinical outcomes after aortic root replacement with transcriptomic analysis of aortic smooth muscle cell dysregulation to investigate mechanisms governing this subtype-specific aortic vulnerability.
Methods: Single institutional experience with aortic root replacement for nondissected aneurysm in patients with Loeys-Dietz syndrome was reviewed for midterm survival and distal aortic events (subsequent aortic intervention, aneurysm, or dissection).

Inter-laboratory replicability is crucial yet challenging in microbiome research. Leveraging microbiomes to promote soil health and plant growth requires understanding underlying molecular mechanisms using reproducible experimental systems. In a global collaborative effort involving five laboratories, we aimed to help advance reproducibility in microbiome studies by testing our ability to replicate synthetic community assembly experiments.

This study aimed to characterize gingival thickness (GT) and determine correlations with other local phenotypic features. CBCT scans from adult subjects involving the maxillary anterior teeth were obtained to assess buccal GT at different apicocoronal levels, periodontal supracrestal tissue height (STH), the distance (CEJ-BC) from the cementoenamel junction (CEJ) to the alveolar bone crest (BC), and buccolingual tooth dimensions. A total of 100 subjects and 600 maxillary anterior teeth comprised the study sample.

Salt stress is one of the main abiotic stresses that affects plant growth and development, as well as crop yield. A large number of studies have reported that the WRKY gene family plays significant roles in the plant responses to salt stress, but the underlying mechanisms remain largely unknown, and research on WRKY proteins in sorghum is also limited. In this study, we identified the sorghum gene SbWRKY51, which encodes a group II WRKY transcription factor.
