Roles of NAC transcription factors in the regulation of biotic and abiotic stress responses in plants

open access: yesFrontiers in Microbiology, 2013
NAC transcription factors are one of the largest families of transcriptional regulators in plants, and members of the NAC gene family have been suggested to play important roles in the regulation of the transcriptional reprogramming associated with plant

Evidence to Suggest that Copulatory Vocalizations in Women Are Not a Reflexive Consequence of Orgasm [PDF]

open access: yes, 2011
The current studies were conducted in order to investigate the phenomenon of copulatory vocalizations and their relationship to orgasm in women. Data were collected from 71 sexually active heterosexual women (M age = 21.68 years ± .52) recruited from the

Large scale genomic analysis of 3067 SARS-CoV-2 genomes reveals a clonal geo-distribution and a rich genetic variations of hotspots mutations.

open access: yesPLoS ONE, 2020
In late December 2019, an emerging viral infection COVID-19 was identified in Wuhan, China, and became a global pandemic. Characterization of the genetic variants of SARS-CoV-2 is crucial in following and evaluating it spread across countries.

Molecular diversity and phylogentic analysis of Capsicum annuum varieties using the nrDNA ITS region

open access: yesScientia Horticulturae, 2014
Abstract The genus Capsicum with its special flavour has been cultivated as a vegetable crop and spread throughout the American, African and Asian tropics. Because the genus Capsicum has various species and varieties, the clear species discrimination is always a focal point of research.

Phylogenetic signal in amphibian sensitivity to copper sulfate relative to experimental temperature [PDF]

open access: yes, 2015
The release of large quantities of chemicals into the environment represents a major source of environmental disturbance. In recent years, the focus of ecotoxicology has shifted from describing the effects of chemical contaminants on individual species ...

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

open access: yes, 2010
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Bacillus subtilis JW1 enhances plant growth and nutrient uptake of Chinese cabbage through gibberellins secretion

open access: yesJournal of Applied Botany and Food Quality, 2019
In the present study, we have isolated rhizospheric bacteria JW1 from rice paddy in Andong, South Korea. The culture filtrate (CF) analysis of JW1 showed higher contents of gibberellins GA1, GA4, GA7, organic acids, fatty acids and tricalcium phosphates.

Co-evolution of male and female reproductive traits across the Bruchidae (Coleoptera) [PDF]

open access: yes, 2008
1. Despite the obvious importance of spermatozoa to individual reproductive success a general explanation of variation in spermatozoan form and function is still lacking. In species with internal fertilization, sperm not only have to interact with the
