Seasonal and diurnal changes of two leaf pathogens of Rubber (Hevea brasiliensis Muell. Arg.) in the air of Iyanomo, Nigeria

open access: yesActa Mycologica, 2014
Air spore concentrations of Drechslera hevea Petch and Colletotrichum gloesporoides Penz were studied in a rubber nursery, over a 12-months period, from March 1976 to February 1977, using both the exposed nutrient medium technique and Rotorod samplers ...

Expression of the HEV2.1 gene promoter in transgenic Hevea brasiliensis

open access: yes, 2008
Hevein is involved in the coagulation of rubber particles and is known to be highly expressed in latex cells from Hevea brasiliensis. As all HEVEIN genes are highly conserved in their transcribed region, a promoter functional analysis was carried out in ...

Genetic diversity of cultivated accessions and wild species of rubber tree using EST‑SSR markers

open access: yesPesquisa Agropecuária Brasileira, 2012
The objective of this work was to evaluate the efficiency of EST‑SSR markers in the assessment of the genetic diversity of rubber tree genotypes (Hevea brasiliensis) and to verify the transferability of these markers for wild species of Hevea. Forty‑five

Deciphering plant–pathogen interaction with single‐cell omics

open access: yesNew Plant Protection, EarlyView.
Recent advances in single‐cell omics have enabled the decoding of gene regulatory networks at the cellular resolution during pathogen challenge. This review summarizes the technological developments in plant single‐cell omics and highlights their unique advantages for dissecting nearly all stages of plant–pathogen interactions, including initial ...

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...
