Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

Natural population analysis

The Journal of Chemical Physics, 1985
A method of ‘‘natural population analysis’’ has been developed to calculate atomic charges and orbital populations of molecular wave functions in general atomic orbital basis sets. The natural analysis is an alternative to conventional Mulliken population analysis, and seems to exhibit improved numerical stability and to better describe the electron ...

Measurement of Natural Selection in Natural Populations

Nature, 1964
VAN VALEN1 has proposed a measure of natural selection intensity as an extension of Haldane's2 measure of intensity I and applied this to data on fossil horses. Van Valen's measure, at least in the example given, is actually a special case of Haldane's I.

Natural selection and population diversity

Journal of Biosocial Science, 1969
It is an observed fact that human populations differ in genetic composition. Some of the inherited diversity is due to combined effects of many genes. Although it would be interesting to know the magnitude and nature of the genetic contribution to some characters under polygenic control, such as intelligence or physique, environmental effects may be so

Population genetics and natural selection

Genetica, 1957
Genotypic differences are the raw material on which selection acts but not all kinds of genotypic differences are of equal importance in this connection. FISHER (1930) showed that whether or not mating occurs at random, the population genotypic variance for any quantitative character may be analyzed into a number of components and that one of these ...

Selection in Natural Populations

1990
The lectures focus on the development of selection component analyses based on population samples including mother-offspring combinations. The need for separation of selection into components is discussed and exemplified by experimental data. The genetic analysis of samples of both simple and complete mother-offspring combinations is developed for one ...

Natural polyelectron population analysis

International Journal of Quantum Chemistry, 1994
AbstractA method to perform a polyelectron population analysis of correlated molecular orbital wave functions on the basis of natural atomic orbitals (NAOs), as given by Weinhold, is presented. The method allows calculations of the probabilities of finding various types of electronic events occuring in some target AO positions, including the ...
