Loss of Pathogenicity and Evidence of Horizontal Gene Transfer in Colletotrichum gloeosporioides From a Medicinal Plant. [PDF]
A Colletotrichum gloeosporioides strain from Huperzia serrata lacks key pathogenicity genes CgDN3 and cap20 and has fewer pelB, pnl and pg genes. pksIII, for synthesis of huperzine A, was probably acquired by the host plant from the fungus. ABSTRACT Colletotrichum gloeosporioides is a major agricultural pathogen of crops that has also been identified ...

This review summarizes the causative agent of tea anthracnose, infection strategies and pathogenicity of C. gloeosporioides, host–pathogen interactions, plant resistance mechanisms, and induced defence against Colletotrichum. Abstract The tea plant (Camellia sinensis) is susceptible to anthracnose disease that causes considerable crop loss and affects ...

Plant sizes and shapes above and belowground and their interactions with climate
Summary Although the above and belowground sizes and shapes of plants strongly influence plant competition, community structure, and plant–environment interactions, plant sizes and shapes remain poorly characterized across climate regimes. We investigated relationships among shoot and root system size and climate.

Alteration of plant species mixtures by virus infection: Managed pastures the forgotten dimension
This review seeks to highlight the major contribution made by past studies in managed pasture towards understanding the impacts of virus infection on the species balance in mixed plant species systems. Abstract What occurs when virus infection is spreading within a mixed plant species population?

Abstract The EFSA Plant Health Panel performed a pest categorisation of Colletotrichum aenigma, C. alienum, C. perseae, C. siamense and C. theobromicola, five clearly defined fungi of the C. gloeosporioides complex causing anthracnose. The pathogens are widely distributed in at least three continents. C. aenigma and C.

Summary Generalised dose–response curves are essential to understand how plants acclimate to atmospheric CO2. We carried out a meta‐analysis of 630 experiments in which C3 plants were experimentally grown at different [CO2] under relatively benign conditions, and derived dose–response curves for 85 phenotypic traits.

The parasitic weed genus Striga causes huge losses to crop production to subsistence farmers in sub‐Saharan Africa. Here, we report a multiyear, landscape‐scale monitoring project for Striga asiatica in the mid‐west of Madagascar. A range of cultural, climatic, and edaphic factors have been identified as driving abundance and distribution, which have ...

Predicting and managing plant invasions on offshore islands
Abstract Resources for biodiversity conservation are limited and it is therefore imperative that management actions that have the best chance of success are prioritized. Non‐native species (NNS) are one of the key problems facing biodiversity conservation, so understanding how NNS disperse and establish can inform more effective conservation planning ...

Commodity risk assessment of Persea americana from Israel
Abstract The EFSA Panel on Plant health was requested to prepare and deliver risk assessments for commodities listed in the relevant Implementing Acts as ‘High risk plants, plant products and other objects’ (Commission Implementing Regulation (EU) 2018/2019 establishing a provisional list of high risk plants, plant products or other objects, within the

Commodity risk assessment of <i>Petunia</i> spp. and <i>Calibrachoa</i> spp. unrooted cuttings from Uganda. [PDF]
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.
