Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Effects of chilling on the expression of ethylene biosynthetic genes in Passe-Crassane pear (Pyrus communis L.) fruits [PDF]

open access: yes, 1997
Passe-Crassane pears require a 3-month chilling treatment at 0 C to be able to produce ethylene and ripen autonomously after subsequent rewarming. The chilling treatment strongly stimulated ACC oxidase activity, and to a lesser extent ACC synthase ...

Analysis of perceived competitive forces influencing tree tomato value chains in Rwanda

open access: yesAfrican Journal of Food, Agriculture, Nutrition and Development
The globalization of economies has added many new challenges to global agriculture. Agriculture not only needs to compete in foreign markets but also in domestic markets. The production and export of tree tomatoes remain extremely weak in Rwanda despite horticulture sector-specific economic policies in favour of the production and export of ...

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Identification of colletotrichum species causing anthracnose on tahiti lime, tree tomato and mango

open access: yes, 2009
In Colombia, citrus, tree tomato and mango crops are likely to suffer considerable losses from anthracnose caused by several Colletotrichum species, which were identified by the present study on infected organs of the three fruit crops, sampled in different regions of the country.

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

open access: yesPest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.
