  pages={1385 - 1389}
Rapid-cycling populations of six economically important species in the genus Brassica have unusual potential for resolving many problems in plant biology and for use in education. Rapid-cycling brassicas can produce up to ten generations of seed per year and serve as models for research in genetics, host-parasite relations, molecular biology, cell biology, plant biochemistry, population biology, and plant breeding. Brassicas are a highly diverse group of crop plants that have great economic…

Rapid-cycling Brassica populations were initially developed as a model for probing the genetic basis of plant disease, but have seen wide application in plant and crop physiology investigations and their extensive use in K-12 education and outreach.

Fast plants for finer science—an introduction to the biology of rapid-cycling Brassica campestris (rapa) L.

Rapid-cycling brassicas, originally developed for plant breeding research, promise to be of value in school and college teaching, and methods for circumventing the flower's self-incompatibility are reviewed.

Characterization of populations of rapid-cycling Brassica rapa L. selected for differential waterlogging tolerance

By challenging a heterogenous population of plants (rapid-cycling Brassica rapa L.) with waterlogging stress, plants which differed in their response to root zone hypoxia were selected and mass-pollinated and re-selected to produce the stable populations described.

Genetics of Brassica rapa L.

This chapter reviews the current use of available molecular marker technologies in B. rapa genetic analysis and breeding for important morphological, agronomic, quality, abiotic and disease resistance QTL/gene mapping and their utilization in marker-assisted breeding.


Recent progress in the development of a system for introducing exogenous DNA in Ceratopteris cells provides a foundation for future studies of the molecular basis of selected traits.

Genetic transformation in oilseed brassicas - A review

The work on regeneration and genetic transformation in the Brassica species will be reviewed and there is still a need for development of efficient transformation methods to overcome genotype dependency.

The Molecular Genetic Basis of Flowering Time Variation in Brassica Species

It has been difficult to obtain a comprehensive picture of the genetic control of morphological diversity in Brassica crops, but for this trait considerable progress in understanding has been made.

Selection and Characterization of Populations of Rapid-Cycling Brassica Rapa L. Differing in Their Response to Rootzone Hypoxia.

Challenging a heterogenous population of plants (rapidcycling Brassica rapa L.) with waterlogging, plants which differed in their response to rootzone hypoxia were selected and mass pollinated to produce the next generation.

Brassica biotechnology: Progress in cellular and molecular biology

The use of molecular markers in marker-assisted selection and breeding, transformation technology for the introduction of desirable traits, and a comparative analysis of these as well as their future prospects are important parts of the current research that is reviewed.

Turnip (Brassica rapa var. rapa L.) Breeding

The efficiency of traditional breeding programs; simple recurrent selection, mass selection and selfing with selection on improving growth, yield and root quality of the Egyptian turnip cultivar Balady have been achieved, and the high-efficiency of a selection-breeding program resulted in improving turnip yield and quality.




It was found by experiment that an effective method of inducing leaf initiation and reducing secondary embryogenesis was to transfer the secondary embryoids to a basal medium supplemented with 6-furfurylaminopurine (kinetin; 10-4 M), alone or in combination with low concentrations of indole-3-acetic acid.

High growth rate and regeneration capacity of hypocotyl protoplasts in some Brassicaceae

To obtain a high frequency of regeneration, rapidly growing calli were transferred to media having a high cytokinin:auxin ratio as early as possible, usually 3 weeks after protoplast isolation.

Influence of Preculture Variables on Microspore Embryo Production in Brassica napus ssp. oleifera cv. Duplo

The study confirmed that the different components of the final embryo yield are differentially affected by the four preculture variables tested and must be controlled if reproducible results are to be achieved.

Minimum-Tillage Forage Turnip and Rape Production on Hill Land as Influenced by Sod Suppression and Fertilizer1

The purpose of this research was to determine the feasibility of producing Brassica spp.

Arabidopsis thaliana and Plant Molecular Genetics

Arabidopsis thaliana is a small flowering plant with various properties that make it an excellent organism for experiments in molecular genetics. These properties include having a small nuclear

Nuclear DNA amounts in angiosperms

This paper contains a supplementary list of absolute DNA values, including estimates for 240 angiosperm species not listed by Bennett & Smith in 1976, as well as additional estimates for 41 species already listed by them.

Tripartite structure of the Brassica campestris mitochondrial genome

Physical mapping studies indicate a novel sequence arrangement, consisting of three circular chromosomes, for the mitochondrial genome of Brassica campestris, and postulated to interconvert with the master chromosome via a co-integration-resolution pathway mediated by reciprocal recombination within the 2-kb repeat.

Changes in the activity of acetyl-CoA carboxylase during rape-seed formation.

During the formation of rape-seeds, lipid accumulated in the cotyledons from 16 days after pollination, rising to a plateau after 28 days, preceded by a marked rise in acetyl-CoA carboxylase activity, which declined rapidly, correlating with the decline in rate of lipid formation.
