Growers race to save orange from spreading disease

37By Heather Smith

MSN News – Increasingly, orange growers have come to believe that genetic engineering holds the only hope for developing a tree that is resistant to an incurable citrus disease.

 Guy Davies, an inspector for the Florida Division of Plant Industry, checks an orange tree for the insect Asian citrus psyllid that carries the bacterium causing disease, “citrus greening” or huanglongbing, from tree to tree on May 13, 2013 in Fort Pierce, Florida.

Botanical Institute discovers seven species of fungi in Paranapiacaba

2By Noêmia Lopes
Agência FAPESP – Conservative estimates put the total number of fungal species in the world at 1.5 million. Although many remain unknown, new studies in the field of mycology are increasing the knowledge on this kingdom every year. Researchers from the São Paulo Environment Secretariat’s Botanical Institute (IBt/SP) have been contributing to these efforts and have just discovered seven new species on the Paranapiacaba Biological Reserve (RBP) in Greater São Paulo.

Experiment in Amazonia becomes global model for research

17By Frances Jones
Agência FAPESP – A scientific project begun 35 years ago in the heart of the Amazon Forest is bearing fruit around the globe. A million-dollar experiment developed by an international team on the island of Borneo in Asia is the most recent study to replicate and expand upon the Dynamic Biological Project on Forest Fragments (PDBFF), the result of cooperation between the National Institute of Amazon Research (Inpa) and the Smithsonian Institution.

The banana (Musa acuminata) genome and the evolution of monocotyledonous plants

Angélique D’Hont et al.
Nature – Bananas (Musa spp.), including dessert and cooking types, are giant perennial monocotyledonous herbs of the order Zingiberales, a sister group to the well-studied Poales, which include cereals. Bananas are vital for food security in many tropical and subtropical countries and the most popular fruit in industrialized countries. The Musa domestication process started some 7,000 years ago in Southeast Asia. It involved hybridizations between diverse species and subspecies, fostered by human migrations2, and selection of diploid and triploid seedless, parthenocarpic hybrids thereafter widely dispersed by vegetative propagation. Half of the current production relies on somaclones derived from a single triploid genotype (Cavendish)… >>Keep reading<<

Extreme climate change linked to early animal evolution

Science News – An international team of scientists, including geochemistries from the University of California, Riverside, has uncovered new evidence linking extreme climate change, oxygen rise, and early animal evolution. A dramatic rise in atmospheric oxygen levels has long been speculated as the trigger for early animal evolution. While the direct cause-and-effect relationships between animal and environmental evolution remain topics of intense debate, all this research has been hampered by the lack of direct evidence for an oxygen increase coincident with the appearance of the earliest animals — until now.

Semi-Dwarf’ Trees May Enable a Green Revolution for Some Forest Crops

Science Daily – The same “green revolution” concepts that have revolutionized crop agriculture and helped to feed billions of people around the world may now offer similar potential in forestry, scientists say, with benefits for wood, biomass production, drought stress and even greenhouse gas mitigation.
