Consistency between molecular phylogeny and morphological classification of the Salix matsudana Koidz. complex (Salicaceae)

S. H. Du, Wang, Z. S., Li, Y. X., Wang, D. S., and Zhang, J. G., Consistency between molecular phylogeny and morphological classification of the Salix matsudana Koidz. complex (Salicaceae), vol. 14, pp. 8663-8671, 2015.

The morphological species concept is based on morpho­logical traits, which are often subject to subjectivity or artifact. Molecular evidence is needed to test the reliability of morphological classification of taxa that are controversial and to provide appropriate taxonomic de­limitation. In this study, we used 15 single-copy nuclear loci and 2 chlo­roplast fragments to verify the morphological classification of the Salix matsudana Koidz. complex using phylogenetic approaches.

Production and genetic characterization of interspecific hybrids among Crambe abyssinica, Crambe hispanica and Crambe kralikii

X. Z. Du, Huang, B. L., Guan, H., Li, Z. Y., and Huang, B. Q., Production and genetic characterization of interspecific hybrids among Crambe abyssinica, Crambe hispanica and Crambe kralikii, vol. 13, pp. 6995-7005, 2014.

In this paper, interspecific crosses among Crambe abyssinica, Crambe hispanica, and Crambe kralikii were reported. In the C. hispanica x C. abyssinica (H x A) cross, 118 F1 hybrids were produced without embryo rescue, while 5 F1 hybrids were obtained with embryo rescue, when C. hispanica was used as the female parent. In the reciprocal cross (A x H), 232 hybrids were obtained without embryo rescue. From more than 1000 C. kralikii flowers pollinated with pollen grains of C.

Genetic diversity of spineless Cereus jamacaru accessions using morphological and molecular markers

F. I. C. Oliveira, Bordallo, P. N., Castro, A. C. R., and Correia, D., Genetic diversity of spineless Cereus jamacaru accessions using morphological and molecular markers, vol. 12, pp. 4586-4594, 2013.

This is the first study to examine the genetic diversity of mandacaru cactus (Cereus jamacaru P. DC.). Plants of spineless mandacaru are commonly found in gardens and parks of urban areas in northeastern Brazil. In addition to exploring their ornamental potential, morphological, and genetic characterization may contribute to the development of plant materials that can be used as a source of macromolecules of potential economic interest.

Genetic characterization of pea (Pisum sativum) germplasm from Turkey using morphological and SSR markers

G. Sarıkamış, Yanmaz, R., Ermiş, S., Bakır, M., Bakır, M., and Yüksel, C., Genetic characterization of pea (Pisum sativum) germplasm from Turkey using morphological and SSR markers, vol. 9, pp. 591-600, 2010.

The need for the conservation of plant genetic resources has been widely accepted. Germplasm characterization and evaluation yield information for more efficient utilization of these valuable resources. The aim of the present study was to characterize the pea germplasm conserved at the Aegean Agricultural Research Institute of Turkey using morphological and simple sequence repeat (SSR)-based molecular approaches.

Unusual chromosome numbers in Paspalum L. (Poaceae: Paniceae) from Brazil

A. P. S. Peñaloza, Côrtes, A. L., Pozzobon, M. T., Santos, S., Rua, G. H., and Valls, J. F. M., Unusual chromosome numbers in Paspalum L. (Poaceae: Paniceae) from Brazil, vol. 7, pp. 399-406, 2008.

Somatic chromosome numbers were determined for 20 new germplasm accessions of Paspalum, belonging to 17 species collected in Brazil. Chromosome number is reported for the first time for P. reduncum (2n = 18), P. cinerascens (2n = 20), P. cordatum (2n = 20), P. filgueirasii (2n = 24), P. ammodes (2n = 36), P. bicilium (2n = 40), P. heterotrichon (2n = 40), and P. burmanii (2n = 48). New cytotypes were confirmed for two germplasm accessions of P. carinatum (2n = 30) and P.
