Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

The growth and yield of maize (Zea mays L.) and soyabeans (Glycine max. (L) Merrill) grown as intercrops : a thesis presented in partial fulfilment of the requirement for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]

open access: yes, 1986
The effect of plant population maize (Zea mays L.) cultivar (Pioneer 3901) and AMT and Matara cultivars of soyabeans (Glucine max (L) Merill) grown together in an intercropping system was studied.

Impact of Simulated Insect Defoliation and Timing of Injury on Cabbage Yield in Minnesota [PDF]

open access: yes, 2018
In 1992 and 1994, field studies were done to assess the tolerance of transplanted cabbage to simulated insect defoliation and to determine if the defoliation level and growth stage at which defoliation begins influences final yield.

Random Forests for Global and Regional Crop Yield Predictions

open access: yesPLoS ONE, 2016
Accurate predictions of crop yield are critical for developing effective agricultural and food policies at the regional and global scales. We evaluated a machine-learning method, Random Forests (RF), for its ability to predict crop yield responses to ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Investigation into the microscopic mechanism underlying formation damage induced by the reinjection of oil-bearing wastewater

open access: yesFrontiers in Earth Science
The reinjection of treated oilfield water into formations stands as one of the commonly employed methods in oilfield water injection development. However, certain treated waters contain a substantial number of suspended oil droplets, which can lead to ...

Influence of alleycropping microclimate on the performance of groundnut (Arachis hypogaea L.) and sesame (Sesamum indicum L.) in the semi-desert region of northern Sudan [PDF]

open access: yes, 2008
An alley cropping system was established at Hudieba Research Station (17.57’N and 33.8’ E) on a loamy sand soil of the semi-desert region of northern Sudan. The objective of this study was to investigate the influence of modified microclimate in 6-m wide

Locally holomorphic maps yield symplectic structures

open access: yes, 2005
For a smooth map $f:X^4\to\Sigma^2$ that is locally modeled by holomorphic maps, the domain is shown to admit a symplectic structure that is symplectic on some regular fiber, if and only if $f^*[\Sigma]\ne0$.

Genetic Diversity of Selected Upland Rice Genotypes (Oryza sativa L.) for Grain Yield and Related Traits [PDF]

open access: yes, 2018
Seventy-seven upland rice genotypes including popular cultivars in Nigeria and introduced varieties selected from across rice-growing regions of the world were evaluated under optimal upland ecology.
