High-throughput analyses of small substances in Nicotiana attenuata reveal that plants re-organize their metabolism to produce highly-specific defense metabolites after insect attack

Researchers have sequenced and analyzed the genome of a single-celled alga that belongs to the closest lineage to terrestrial plants and provides many clues to how aquatic plants first colonized land.
The effective management of plant diseases is of fundamental importance for forestry, food, and other plant-derived product productions, as well as for the sustainability of natural environments. Changing global climate patterns and the trade of planting materials across the borders are causing plant pathogens to rapidly move and evolve. That is plant pathogens, are changing their behavior, survival, reproduction, and mode of action in the host plants.
Over 80% of the world’s flowering plants must reproduce in order to produce new flowers, according to the U.S. Forest Service. This process involves the transfer of pollen between plants by wind, water or insects called pollinators — including bumblebees. In a new study, researchers discovered a spiny pollen that has evolved to attach to traveling bumblebees.
Researchers have discovered a new species of seaweed Calidia pseudolobata as well as four new genera of red algae from the warm waters of China. The research suggests there are many new species yet to be discovered – with potential implications for marine biodiversity and food security.
Scientists have identified five Romaine lettuce varieties that both brown less quickly after fresh-cut processing and are slower to deteriorate postharvest. They also are determining the genetic basis for deterioration.
The native guava is one of the first Australian plants to be pushed to the brink of extinction by a fungal plant disease which has spread rapidly across the globe, according to a new study.
Plant leaves exhibit a great diversity of forms that can be grouped into two types: simple leaves with a single blade and compound leaves with multiple units termed leaflets. A major question for plant developmental biologists is the molecular mechanism underlying diversity of compound leaf form during evolution.
A team of researchers has developed an innovative software program for the simulation of breeding programmes. The “Modular Breeding Program Simulator” (MoBPS) enables the simulation of highly complex breeding programmes in animal and plant breeding and is designed to assist breeders in their everyday decisions.
Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. In a new study, scientists have uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of agricultural applications.
