Genome structure of tobacco rattle virus strain PLB: further evidence on the occurrence of RNA recombination among tobraviruses.
Replicase-mediated resistance to alfalfa mosaic virus.
With the GGD, GVD, and DDD mutants, resistance was generally observed in plants with a relatively high expression level, indicating that the resistance is due to the mutant replicase rather than to an RNA-mediated cosuppression phenomenon.
Global COVID-19 lockdown highlights humans as both threats and custodians of the environment

No or only weak correlations were found between different in vitro characteristics such as plant growth, protoplast yield per gram plant material, plating efficiency and callus growth, which indicates the unpredictability of these characters.

A rich record of observational plant phenology data is used to evaluate how well gridded maps of the spring index models predict leaf and flowering onset dates in 19 species of ecologically important, broadly distributed deciduous trees and shrubs and the lilac and honeysuckle species used to construct the models.
Solenodon paradoxus (Soricomorpha: Solenodontidae)
S. paradoxus is 1 of 2 extant species in the genus Solenodon, and 2 subspecies are recognized; the species is one of few venomous mammals with venom delivery through a channel in a modified lower incisor.
Nature's Notebook and Extension: Engaging Citizen-Scientists and 4-H Youth to Observe a Changing Environment.
Extension, with its access to long-term volunteers, has the unique ability to teach citizen scientists about the connection between climate variability and the resulting effects on plants, animals,…
