EXAMINATION OF NONSTERILE Preparation of Test Strains PRODUCTS: MICROBIAL Use standardized stable suspensions of test strains or prepare as stated below. Seed-lot culture maintenance techENUMERATION TESTS niques (seed-lot systems) are used so that the viable microorganisms used for inoculation are not more than five passages removed from the original master seed-lot. Grow each of the bacterial ...

SEED is a database system which supports the data engineering needs of a software engineering environment. It provides information structures that are not incorporated in conventional database systems, but are typical in the software engineering process. This paper describes two principal features of SEED: how to deal with vague and incomplete information without giving up consistency checking,...

This is the third in a series of four papers which we consider system interacting Fisher-Wright diffusions with seed-bank. Individuals carry type ♡ or ♢, live colonies, and are subject to resampling migration as long they active. Each colony has structured seed-bank into individuals can retreat become dormant, suspending their until active again. As geographic space labelling colonies countable...

Seed-caching rodents have long been seen as important actors in dispersal ecology. Here, we focus on the interactions with plants in a fire-disturbance community, specifically Arctostaphylos species (Ericaceae) in California chaparral. Although mutualistic relationships between caching rodents and plants are well studied, little is known how this type of relationship functions in a disturbance-...

Introduction The purpose of a seed train is the generation of an adequate number of cells for the inoculation of a production bioreactor. This is timeand cost-intensive: From volumes used for cell thawing or cell line maintenance the cell number has to be increased. The cells are usually run through many cultivation systems which become larger with each passage (e.g. T-flasks, roller bottles or...

A digital image of a plant seed can be regarded as a two-dimensional object which can be measured in size, shape and color density during the development stage of germination by computer image analysis technology. Seed changes its biological structure passing from a quiescent stage to a proliferating one, and any morphological variation can be associated with the corresponding variation of seed...

Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...
