13. Diversidade em quatro áreas de campos rupestres na Chapada Diamantina, Bahia, Brasil: espécies distintas, mas riquezas similares
ABSTRACT This study aims at detecting patterns of diversity on 'campos rupestres', providing useful information to conservation strategies. Four sites in the Chapada Diamantina´s summits were studied, including two kinds of open physiognomies, one more grassy and homogenous (continuous habitat) and the other more shrubby and heterogeneous (insular habitat).

14. In silico survey of resistance (R) genes in Eucalyptus transcriptome
A major goal of plant genome research is to recognize genes responsible for important traits. Resistance genes are among the most important gene classes for plant breeding purposes being responsible for the specific immune response including pathogen recognition, and activation of plant defence mechanisms. These genes are quite abundant in higher plants, wit

15. PolinizaÃÃo e fenologia reprodutiva de Byrsonima gardnerana A. Juss. (Malpighiaceae) em Ãrea de Caatinga/Nordeste do Brasil
The flowers, which offer onlu oil as floral reward for their pollinators or pollen added to oil, are agrouped in nine families (Iridaceea e Orchidaceae â Monocots; Cucurbitaceae, Primulaceae, Krameriaceae, Malpighiaceae, Solanaceae, Calceolariaceae e Plantaginaceae - Eudicots), 79 genera and about 2.400 species, and are widespread for the entire world.

16. The leaves of green plants as well as a cyanobacterium, a red alga, and fungi contain insulin-like antigens
We report the detection of insulin-like antigens in a large range of species utilizing a modified ELISA plate assay and Western blotting. We tested the leaves or aerial parts of species of Rhodophyta (red alga), Bryophyta (mosses), Psilophyta (whisk ferns), Lycopodophyta (club mosses), Sphenopsida (horsetails), gymnosperms, and angiosperms, including monocot

17. Scanning electron microscope studies of Agrobacterium tumefaciens attachment to Zea mays, Gladiolus sp., and Triticum aestivum.
Scanning electron microscope studies demonstrated that cells of Agrobacterium tumefaciens strains attach to cells on the cut surfaces of corn and wheat seedlings and to gladiolus disks. Bacterial cells attached to these monocots in the same manner as they attached to the dicots tested. Of the strains tested, A66 and T37 covered more of the cut surfaces of th

18. The Structure of Plant Cell Walls: VI. A Survey of the Walls of Suspension-cultured Monocots 1
The primary cell walls of six suspension-cultured monocots and of a single suspension-cultured gymnosperm have been investigated with the following results: (a) the compositions of all six monocot cell walls are remarkably similar, despite the fact that the cell cultures were derived from diverse tissues; (b) the cell walls of suspension-cultured monocots di

19. A Survey of the Pectic Content of Nonlignified Monocot Cell Walls
The primary cell walls of graminaceous monocots were known to have a low content of pectin compared to those of dicots, but it was uncertain how widespread this feature was within the monocots as a whole. Nonlignified cell walls were therefore prepared from 33 monocot species for determination of their pectin content. It was not possible to solubilize intact

22. Evaluation of Monocot and Eudicot Divergence Using the Sugarcane Transcriptome1[w]
Over 40,000 sugarcane (Saccharum officinarum) consensus sequences assembled from 237,954 expressed sequence tags were compared with the protein and DNA sequences from other angiosperms, including the genomes of Arabidopsis and rice (Oryza sativa). Approximately two-thirds of the sugarcane transcriptome have similar sequences in Arabidopsis. These sequences m

23. Plant intron sequences: evidence for distinct groups of introns.
In vivo and in vitro RNA splicing experiments have demonstrated that the intron splicing machineries are not interchangeable in all organisms. These differences have prevented the efficient in vivo expression of monocot genes containing introns in dicot plants and the in vitro excision of some plant introns in HeLa cell in vitro splicing extracts. We have an

24. Araceae from the Early Cretaceous of Portugal: Evidence on the emergence of monocotyledons
A new species (Mayoa portugallica genus novum species novum) of highly characteristic inaperturate, striate fossil pollen is described from the Early Cretaceous (Barremian–Aptian) of Torres Vedras in the Western Portuguese Basin. Based on comparison with extant taxa, Mayoa is assigned to the tribe Spathiphylleae (subfamily Monsteroideae) of the extant mono
