Quinoa (Chenopodium quinoa) is an important crop for the future challenges of food and nutrient security. Deep characterization of quinoa diversity is needed to support the agronomic improvement and adaptation of quinoa as its worldwide cultivation expands. In this study, we report the construction of chromosome-scale genome assemblies of eight quinoa accessions covering the range of phenotypic and genetic diversity of both lowland and highland quinoas.

Article Synopsis
  • Penstemons are flowering plants native to the Rocky Mountains, often used in urban landscaping, but elite varieties struggle with abiotic stresses like drought and salinity.
  • Firecracker penstemon (Penstemon eatonii) is more resilient to these stresses and can hybridize with other penstemon species, offering a way to create more tolerant cultivars.
  • Researchers sequenced the genome of a firecracker penstemon from Utah and additional accessions, creating the most complete penstemon genome assembly so far.

Article Synopsis
  • - The study analyzed smoking trends in Australia from 1910 to 2005, focusing on initiation and cessation rates among different age groups and genders to assess the impact of historical tobacco control policies.
  • - Among nearly 30,000 participants, 56.8% reported having smoked, with young males showing consistently high initiation rates from 1910-1999, while young females saw a significant rise in smoking in the 1960s and 1970s.
  • - The results revealed that while smoking cessation rates increased overall for ages 36-50, they plateaued for females and decreased for males post-1990, highlighting the varying effectiveness of tobacco control measures, particularly among younger individuals.
