Chromosome Sleuthing Reveals Hidden Karyotype Diversity in Iran’s Carrot
2+ day, 10+ hour ago (802+ words) Deep in the mountains and arid plains of Iran, a quiet revolution in plant science is taking shape under the microscope. A new cytogenetic investigation has charted the chromosomes of thirty species spanning sixteen genera of Apioideae, the largest and…...
ATRX partners with 9-1-1 and CST to protect genome replication and
1+ week, 2+ day ago (838+ words) Every time a human cell divides, it must copy roughly six billion letters of DNA—a feat accomplished by molecular machines that race along the double helix at breakneck speed. But the replication machinery routinely encounters obstacles: tightly bound proteins,…...
How Design, Modeling, and Spatial Analysis Shape Genomic Selection
2+ week, 1+ day ago (71+ words) Plant breeders may be able to test far more crop varieties without sacrificing the accuracy of genomic predictions, according to a large simulation study spanning maize, sunflower and oat. The research found that partially replicated field designs—plots in which…...
Plant Cross-Incompatibility Limits Genome Exchange and Gene Pool
2+ week, 4+ day ago (878+ words) Crop wild relatives may hold the genetic tools needed to help agriculture withstand drought, heat, salinity, emerging diseases and increasingly unstable growing conditions. Yet the same evolutionary distance that preserved these valuable traits often prevents breeders from moving them into…...
Pepper Study Links Ultra-Long Centromere Haplotypes to Evolution and
2+ week, 4+ day ago (54+ words) Pepper plants may be hiding some of their most consequential genetic variation in regions long treated as difficult, repetitive stretches of DNA. A study published in Nature Ecology & Evolution reports that ultra-long haplotypes surrounding pepper centromeres can extend across tens…...
