Salt tolerance at germination and seedling growth stages was investigated. GWAS revealed nine genomic regions with pleiotropic effects on salt tolerance. Salt tolerant genotypes were identified for future breeding program.
View Article and Find Full Text PDFTitanium dioxide nanoparticle (nTiO2) is one of the most produced nanoparticles worldwide. Its mechanism on crop development and performance is unclear as it is hard to predict their toxicity or benefit. Therefore, understanding the genetics of crop development under nTiO2 is a prerequisite for their applications in agriculture and crop improvement.

- - The study investigates factors affecting post-transplant survival in pediatric liver transplant (PLT) patients over time, focusing on data from 2000 to 2019 at a single transplant unit.
- - Key findings reveal that recipient age, weight, height, and transplant category significantly influence patient survival, with invasive ventilation noted as a critical factor for those transplanted after 2005.
- - The research highlights that technical advancements and learning curves have positively impacted patient outcomes, suggesting a revision of the belief that smaller candidates have worse survival rates.
Drought stress can occur at any growth stage and can affect crop productivity, which can result in large yield losses all over the world. In this respect, understanding the genetic architecture of agronomic traits under drought stress is essential for increasing crop yield potential and harvest. Barley is considered the most abiotic stress-tolerant cereal, particularly with respect to drought.

- Toxins like (-)-botryodiplodin can create areas of dead tissue on soybean roots, which may help fungi infect the plants more easily.
- Laboratory tests showed that (-)-botryodiplodin from both natural and synthesized sources caused similar harmful effects on soybean leaf discs, indicating its role in plant toxicity.
- Additionally, experiments with soybean seedlings demonstrated that (-)-botryodiplodin negatively impacted root growth and structure, supporting its potential to promote fungal infection in healthy roots.
Article Synopsis
- Drought significantly impacts seed germination and plant growth, presenting a challenge to crop productivity, particularly in barley, which is known for its resilience to abiotic stresses.
- A study examined 218 barley accessions under drought stress using PEG, revealing that stress reduced germination and seedling traits and identified several genomic regions linked to these traits through genome-wide association scanning (GWAS).
- The research found 338 single nucleotide polymorphisms (SNPs) related to drought tolerance and identified quantitative trait loci (QTL) on specific chromosomes, highlighting the role of specific genes in managing drought stress during seed germination.
The response of L. seedlings subjected to salinity was investigated through the observation of germination at the 4th, 6th and 8th days under normal and two salinity levels (150 and 200 mM NaCl). Genetic response of .

The effects of carbon, Fe2O3 and Na2SO4 contents on the amber color of glass with composition (wt%) 64.3 SiO2, 25.7 CaO, 10 Na2O were studied.
View Article and Find Full Text PDFThree strains of filamentous Cyanobacteria were used to study their growth and utilization of organophosphorus pesticide malathion. A sharp decrease in the growth of the algal strains was observed by increasing the concentration of malathion. Amongst them Nostoc muscorum tolerated different concentrations and was recorded as the highest efficient strain for biodegradation (91%) of this compound.
