Question

Asked 4th Feb, 2015

I would like to simulate a fungal infection of Altenaria sp. because unfortunatelly we can not grow plants with the fungus. Any ellicitor to do? What do you think about mechanical injury?

Thank you in advance

Dear Raquel,

you may try to simulate its growth as mass diffusion in porous media, and with first order reaction and a point source as a start. kk

Dear kheng,

Thank you very much for you fast aswer

Please can you specify a bit more. I don´t understand very well. Any publication??

Best

Dear Raquel,

I upload a paper on gas diffusion in porous media and a PPT on gas diffusion in liquid that lead to convection for your reference. You need to combine both concepts in one set up in FLUENT, and add reaction, but remove g force to stop convection. You can estimate the time steps from the spreading rate of Altenaria sp. kk

GLMM for negative values response variable?

I have been trying to fit a glmm model with lme4 package with a dataset that results from a meta-analysis, so it has several negative values at the response variable (yi).

The data are not normally distributed:

The code I am using to run this and include ID effect as a random factor is below.

res.glmer <- glmer(yi ~ 1 + (1 |ID), data=ex_dataset, family=" ")

glmer function does not seem to handle negative values and I also don´t really know what family to indicate to the model.

Any ideas of how to make this analysis?

Rust fungi like Puccinia graminis f. sp. tritici are known to change their cell wall properties upon entering the plant tissue. Immunohistochemistry revealed the cellular localization of two class III chitin synthase isoforms in rust mycelia developing on and in the host plant. Isoform IIIa is restricted to fungal infection structures growing on th...
