The Genetics and Genomics of the Brassicaceae provides a review of this important family (commonly termed the mustard family, or Cruciferae). The family contains several cultivated species, including radish, rocket, watercress, wasabi and horseradish, in addition to the vegetable and oil crops of the Brassica genus. There are numerous further species with great potential for exploitation in 21st century agriculture, particularly as sources of bioactive chemicals. These opportunities are reviewed, in the context of the Brassicaceae in agriculture. More detailed descriptions are provided of the genetics of the cultivated Brassica crops, including both the species producing most of the brassica vegetable crops (B. rapa and B. oleracea) and the principal species producing oilseed crops (B. napus and B. juncea). The Brassicaceae also include important “model” plant species. Most prominent is Arabidopsis thaliana, the first plant species to have its genome sequenced. Natural genetic variation is reviewed for A. thaliana, as are the genetics of the closely related A. lyrata and of the genus Capsella. Self incompatibility is widespread in the Brassicaceae, and this subject is reviewed. Interest arising from both the commercial value of crop species of the Brassicaceae and the importance of Arabidopsis thaliana as a model species, has led to the development of numerous resources to support research. These are reviewed, including germplasm and genomic library resources, and resources for reverse genetics, metabolomics, bioinformatics and transformation. Molecular studies of the genomes of species of the Brassicaceae revealed extensive genome duplication, indicative of multiple polyploidy events during evolution. In some species, such as Brassica napus, there is evidence of multiple rounds of polyploidy during its relatively recent evolution, thus the Brassicaceae represent an excellent model system for the study of the impacts of polyploidy and the subsequent process of diploidisation, whereby the genome stabilises. Sequence-level characterization of the genomes of Arabidopsis thaliana and Brassica rapa are presented, along with summaries of comparative studies conducted at both linkage map and sequence level, and analysis of the structural and functional evolution of resynthesised polyploids, along with a description of the phylogeny and karyotype evolution of the Brassicaceae. Finally, some perspectives of the editors are presented. These focus upon the Brassicaceae species as models for studying genome evolution following polyploidy, the impact of advances in genome sequencing technology, prospects for future transcriptome analysis and upcoming model systems.

The second monograph devoted to the work of the Theban Desert Road Survey presents the major rock inscriptions of the northwestern Theban Desert and the western hinterlands of Qamula. The material includes six larger sites and several smaller collections and individual inscriptions and images, sites discovered by the Theban Desert Road Survey over the course of approximately twelve field seasons. The major groupings of inscriptions, from south to north, are the rock shrine of Pahu and the inscriptions of Gebel Akhenaton, sites in the vicinity of the Wadi Himdaniya; a small but interesting collection of inscriptions near the Wadi Arqub Baghla, with two smaller, outlying sites; inscriptions of the Wadi Magar to the north, including the site of the great Predynastic tableau with its plethora of crocodiles, the associated vignette of Elephant-on-the-Gebel, along with the nearby Gebel Sutekh site, and smaller concentrations beyond; and finally the inscriptions of the area of the Matna el-Barqa. Highlights of the epigraphic material include new prayers to Amun and Hathor-one a genuine New Kingdom de profundis recording an appeal to Amun during a storm on the Nile-several important Predynastic and Protodynastic tableaux, and the only rock art depictions of Akhenaton in a true Amarna style.
