The flowering plant Arabidopsis thaliana is an important model system for identifying genes and determining their functions. Here we report the analysis of the genomic sequence of Arabidopsis. The sequenced regions cover 115.4 megabases of the 125-megabase genome and extend into centromeric regions. The evolution of Arabidopsis involved a whole-genome duplication, followed by subsequent gene loss and extensive local gene duplications, giving rise to a dynamic genome enriched by lateral gene transfer from a cyanobacterial-like ancestor of the plastid. The genome contains 25,498 genes encoding proteins from 11,000 families, similar to the functional diversity of Drosophila and Caenorhabditis elegans - the other sequenced multicellular eukaryotes. Arabidopsis has many families of new proteins but also lacks several common protein families, indicating that the sets of common proteins have undergone differential expansion and contraction in the three multicellular eukaryotes. This is the first complete genome sequence of a plant and provides the foundations for more comprehensive comparison of conserved processes in all eukaryotes, identifying a wide range of plant-specific gene functions and establishing rapid systematic ways to identify genes for crop improvement.

The ability to recognize and repair abnormal DNA structures is common to all forms of life. Studies in a variety of species have identified an incredible diversity of DNA repair pathways. Documenting and characterizing the similarities and differences in repair between species has important value for understanding the origin and evolution of repair pathways as well as for improving our understanding of phenotypes affected by repair (e.g., mutation rates, lifespan, tumorigenesis, survival in extr...

Arabidopsis thaliana is a small flowering plant that serves as the major model system in plant molecular genetics'. The efforts of many scientists have produced genetic maps that provide extensive coverage of the genome (http://genome-www.stanford.edulArabidopsis/maps.html). Recently, detailed YAC, BAG, P1 and cosmid-based physical maps (that is, representations of genomic regions as sets of overlapping clones of corresponding libraries) have been established that extend over wide genomic areas ...

Cellulose, polymers of glucose organized into long fibrils, forms the bulk of the world's biomass. But the identity of the enzyme that makes this critical substance has been uncertain. In this week's issue, [ Arioli et al .][1] report the first confirmation that the gene CelA is indeed a cellulose synthase, and Carpita and Vergara, in their research commentary, explain why this result has been so long in coming and what we now know about how cellulose is made.

The fruit, which mediates the maturation and dispersal of seeds, is a complex structure unique to flowering plants. Seed dispersal in plants such as Arabidopsis occurs by a process called fruit dehiscence, or pod shatter. Few studies 1-3 have focused on identifying genes that regulate this process, in spite of the agronomic value of controlling seed dispersal in crop plants such as canola 4,5 . Here we show that the closely related SHATTERPROOF (SHP1) and SHATTERPROOF2 (SHP2) MADS-box genes are ...

Chromodomains are thought to mediate protein-protein interactions between chromatin components. We have detected a chromodomain embedded within the catalytic region of a predicted Arabidopsis DNA methyltransferase that is diverged from other eukaryotic enzymes. The 791 residue "chromomethylase" (CMT1) is encoded by a floral transcript that is spliced from 20 exons and is present at only approximately 1/10(-7) of total mRNA. Genomic sequencing reveals an ancient haplotype split at CMT1 between Co...

The genetic positions of the five Arabidopsis thaliana centromere regions have been identified by mapping size polymorphisms in the centromeric 180-bp repeat arrays. Structural and genetic analysis indicates that 180-bp repeat arrays of up to 1000 kb are found in the centromere region of each chromosome. The genetic behavior of the centromeric arrays suggests that recombination within the arrays is suppressed. These results indicate that the centromere regions of A. thaliana resemble human centr...

The discovery of cyanobacterial phytochrome histidine kinases, together with the evidence that phytochromes from higher plants display protein kinase activity, bind ATP analogs, and possess C-terminal domains similar to bacterial histidine kinases, has fueled the controversial hypothesis that the eukaryotic phytochrome family of photoreceptors are light-regulated enzymes. Here we demonstrate that purified recombinant phytochromes from a higher plant and a green alga exhibit serine/threonine kina...

The assembly of the higher plant cytoskeleton poses several fundamental ques- tions. Since different microtubule arrays are successively assembled during the cell cycle in the absence of centrosomes, we can ask how these arrays are assembled and spatially organized. Two hypotheses are under debate. Either multiple nucleation sites are responsible for the assembly and organization of microtubule arrays or microtubule nucleation takes place at one site, the nuclear surface. In the latter case, mic...

Many plant species have obtained the capability to resist freezing and/or low temperatures and have thus extended their geographical distribution into regions with cold climates. A number of studies have been carried out to try to determine how these plants acclimate to low temperatures and survive under freezing conditions, and the results of those studies have indicated that irreversible damage in the plasma membrane that occurs during freeze-induced dehydration is the primary cause of freezin...

Genetically determined self-incompatibility (SI) systems ensure high rates of out-crossing because they allow the pistil to recognise and reject genetically identical pollen. As such, SI systems are thought to be advantageous because populations with high levels of polymorphism have the genetic variability required for withstanding a wide range of environmental challenges. Nevertheless, SI has repeatedly been lost in plant lineages, and it has been noted that the most frequently travelled path i...

Abstract The aquatic ferns of the genus Azolla are nitrogen-fixing plants that have great potentials in agricultural production and environmental conservation. Azolla in many aspects is qualified to serve as a model organism for genomic studies because of its importance in agriculture, its unique position in plant evolution, its symbiotic relationship with the N 2 -fixing cyanobacterium, Anabaena azollae , and its moderate-sized genome. The goals of this genome project are not only to understand...

Elucidation of the roles of circadian associated factors requires a better understanding of the molecular mechanisms of circadian rhythms, control of flowering time through photoperiodic pathways, and photosensory signal transduction. In Arabidopsis, the APRR1 quintet, APRRs 1, 3, 5, 7, and 9, are known as central oscillator genes. Other plants may share the molecular mechanism underlying the circadian rhythm. To identify and characterize these circadian response genes in Brassica crops whose ge...

Abstract Chitinase modifying proteins, cmps, are secreted fungal proteases that truncate specific plant class IV chitinases by cleaving peptide bonds in their amino termini. We recently identified a cmp from the Zea mays (maize) pathogen Fusarium verticillioides and found that it is a member of the fungalysin class of proteases. We also found that Alternaria brassicae , a pathogen of the mustard plant family Brassicaceae, secretes a protease with the same activity. To determine which pathogens o...
