The common fig tree (Ficus carica L.) is a Mediterranean crop with problematic cultivar identification. The recovery and conservation of possible local varieties for ecological production requires the previous genetic characterization of the available germplasm. In this context, 42 lines corresponding to 12 local varieties and two caprifigs, in addition to 15 reference samples have been fingerp...

Pinus Jantho Forest (PJF) Nature Reserve has unique characteristics and distinctive ecosystem that plays an important role in the preservation of germplasm protection natural resources. The sustainability PJF is strongly determined by vegetation its constituents. Therefore, effort needed to help management properly, one which knowing diversity plants make up community Reserve. purpose this rese...

Poaceae (formerly known as Gramineae) is often considered to be the most important of all plant families to human economies. From evolutionary point of view, wheat is a young polyploid and its genetic configuration is a classical example of cereals phylogenic relationship. The genetic diversity of the elite germplasm have been used by plant breeders for numerous reasons such as germplasm manage...

PREMISE OF THE STUDY Assessing genetic distinctness or redundancy is an important part of plant germplasm characterization. We previously introduced a new marker-based approach using the average dissimilarity of an accession to assess genetic distinctness or redundancy. However, this approach has not been widely applied, largely due to the lack of software to integrate separate analyses involvi...

Since the 1960’s, attempts have been made to reduce alfalfa flower damage from Lygus bug feeding by developing resistant alfalfa varieties. Much of this work was conducted at New Mexico State University by Dr. B. A. Melton and his graduate students (Vering 1968, Knipe 1969, Arledge 1972, Auld 1973). In order to identify plants that could withstand damage from Lygus. bug feeding these workers de...

Introduction It is well known that cryopreserved semen could be used to regenerate commercial or research poultry lines; however, fertility rates from poultry semen frozen with current methods are not reliable enough for germ-line retrieval, especially from lines with low reproductive efficiency. As part of a long-term research plan to determine how and why poultry sperm lose functional compete...

MicroRNAs (miRNAs) play essential roles in plant development, but the roles in the in vitro plant development are unknown. Leaves of ponkan plantlets derived from mature embryos at in vitro culture conditions were used to sequence small RNA fraction via Solexa sequencing, and the miRNAs expression was analyzed. The results showed that there were 3,065,625 unique sequences in ponkan, of which 0....

Germination inhibitors, which inhibit the germination of seeds, spores and other plant reproductive material, are abundant in kingdom include phenols, cyanides, alkaloids, essential oils, amino acids, etc. These inhibitors can be classified as destructors retarders depending on whether they harm morphology, structure physiology seed. closely related to seed dormancy, exogenous used extend “dorm...
