Biological parameters of Bemisia tabaci (Gennadius) Biotype B (Hemiptera: Aleyrodidae) on Jatropha gossypiifolia, Commercial (Manihot esculenta) and wild cassava (Manihot flabellif... por Carabalí, A., Bellotti, Anthony C., Montoya Lerma, J.

“…Recent studies indicate that it is possible, however, for biotype B to gradually adapt to cassava using phylogenetically related hosts. Therefore, the possibility that some wild species of cassava constitute intermediate hosts in the adaptation process may lead to the establishment of biotype B on commercial varieties of Manihot esculenta. …”

Historical biogeography of five characidium fish species: dispersal from the amazon paleobasin to Southeastern South America por Poveda-Martínez, Daniel, Sosa, Chrystian C., Chacón-Vargas, Katherine, García Merchán, Víctor Hugo

“…The biogeographic history of five species of the genus was analyzed through nuclear RAG-2 and mitochondrial 16S genes and a time-calibrated phylogenetic analysis using three outgroup species. A biogeographical reconstruction was performed to estimate ancestral geographic ranges and infer the historical events that impacted the geographic distributions of Characidium species. …”

Genetic structure and diversity of Phakopsora pachyrhizi isolates from soyabean por Twizeyimana, M., Ojiambo, P.S., Haudenshield, J.S., Caetano‐Anollés, G., Pedley, K.F., Bandyopadhyay, Ranajit, Hartman, G.L.

“…Low population differentiation was indicated by the low FST values among populations, suggesting a wide dispersal of identical genotypes on a regional scale. Phylogenetic analysis indicated a strictly clonal structure of the populations and five main groups were observed, with group II accounting for 30% of the entire population. …”

Two nucleotide positions in the Citrus exocortis viroid RNA associated with symptom expression in Etrog citron but not in experimental herbaceous hosts por Murcia, Nubia, Bernad, Lucia, Durán-Vila, Núria, Serra, Pedro

“…A new CEVd strain (CEVdCOL), phylogenetically clustering with CEVd variants of Class A inducing severe symptoms in tomato, was identified in Colombia and shown to induce only extremely mild symptoms in Etrog citron indicator plants. …”

The GH3 family in plants: Genome wide analysis in rice and evolutionary history based on EST analysis por Terol, Javier, Domingo, Concha, Talón, Manuel

“…The data indicated that the members of the GH3 family progressively increased in the different plant divisions from Chlorophyta (0), Bryophyta (3), and Coniferophyta (4), to Magnoliophyta (7-19). Phylogenetic analyses showed a high degree of conservation between Arabidopsis and rice GH3 proteins and, in general, in the plant kingdom. …”

Molecular population genetics of Cucumber mosaic virus in California: Evidence for founder effects and reassortment por Lin, H. X., Rubio, Luis, Smythe, A. B., Falk, Bryce W.

“…Extremely low diversity and close evolutionary relationships among isolates in a subpopulation suggested that founder effects might play a role in shaping the genetic structure. Phylogenetic analysis indicated a naturally occurring reassortant between subgroup IA and IB isolates and potential reassortants between subgroup IA isolates, suggesting that genetic exchange by reassortment contributed to the evolution of the California CMV population. …”

Variability of the coat protein gene of Citrus psorosis virus in Campania, southern Italy por Alioto, D., Malfitano, M., Troisi, A., Peluso, A., Martin, Susana, Milne, R. G., Guerri, José, Moreno, Pedro

“…Diversity was slightly higher in region V than in region C. Phylogenetic analysis of the V and C regions of the CP showed that the Campania sources of CPsV were clearly separated from the CPsV-4 isolate from Florida. …”

Molecular characterization of the faecal fungal flora in healthy horses por Khajouei, Ehsan

“…The fungal internal transcribed regions (ITS) and the eukaryotic 18S rRNA genes, recovered from faecal samples of 16 Swedish Standardbred geldings, were used as phylogenetic marker genes in the analyses. Faecal samples were analyzed by TRFLP and two clone libraries were constructed, one library for the 18S gene and the other for the ITS gene from which later 44 random clones were sequenced. …”

Natural variation of OsLG3 controls drought stress tolerance in rice by inducing ros scavenging por Xiong, Haiyan, Yu, Jianping, Li, Jinjie, Wang, Xin, Liu, Pengli, Zhang, Hongliang, Zhao, Yan, Yin, Zhigang, Li, Yang, Guo, Yan, Fu, Binying, Wang, Wensheng, Li, Zhikang, Ali, Jauhar, Li, Zichao

“…Transgenic rice with enhanced OsLG3 expression exhibited improved tolerance to drought and that is most likely due to enhanced ROS scavenging efficiency. Phylogenetic analysis and pedigree records indicated that the tolerant allele of OsLG3 has potential to improve drought tolerance of japonica rice.ConclusionsCollectively, our work revealed that the natural variation of OsLG3 contributes to rice drought tolerance and the elite allele of OsLG3 is a promising genetic resource for the development of drought-tolerant and high-yield rice varieties.…”
