Researchers have sequenced the genome of the waterlily aphid, a unique aphid species that can thrive in both aquatic and terrestrial environments. This high-quality reference genome will help us understand aphid evolution, host plant adaptation, and develop pest control strategies.
Researchers used high-throughput sequencing to sequence and analyze cherry virus A (CVA) and little cherry virus 1 (LChV1) isolates found on interspecies hybrids in Russia. The study expands knowledge on the geographical distribution and genetic diversity of these economically important stone fruit viruses.
Scientists searched for genetic variations in translation initiation factors (eIF4E and eIFiso4E) in stone fruit trees to find alleles associated with resistance to the Plum pox virus (PPV). They identified new alleles in wild species that showed reduced susceptibility to PPV, potentially providing new sources of resistance.
Reactive oxygen species (ROS) are by-products of oxidation/reduction reactions that can damage higher plant cells through oxidative stress. This review discusses enzymatic antioxidants, including superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), as well as non-enzymatic defenses like ascorbic acid, glutathione, flavonoids, carotenoids, and tocopherols that protect against ROS. The study explores the role of ROS scavenging systems during seasonal changes and developmental events like fruit ripening and senescence that impact fruit quality and highlights Prunus and Citrus species due to their nutritional and antioxidant properties. These findings help to understand the importance of antioxidants in protecting plants and their potential health benefits for humans.
