Abstract:
... A procedure for protoplast isolation and plant regeneration of St. John's wort has been developed to utilize cell-to-cell variability for optimum production of valuable medicinal compounds. Calluses, induced from hypocotyl segments of St. John's wort seedlings, were used for protoplast isolation, induction of sustained cell division, and ultimately, plant regeneration. Callus-isolated protoplasts ...

Abstract:
... Uniola paniculata, commonly known as sea oats, is a C4 perennial grass capable of stabilizing sand dunes. It is most abundant along the Gulf of Mexico and southeastern Atlantic coastal regions of the United States. The species exhibits low seed set and low rates of germination and seedling emergence, and so extensive clonal reproduction is achieved through production of rhizomes, which may contrib ...

Abstract:
... The island of Madeira harbours highly differentiated Robertsonian (Rb) races of the house mouse (Mus musculus domesticus), carrying several unique Rb fusions. The reproductive and geographical isolation between these races is expected to restrict gene flow severely, and contribute to their genetic differentiation. In the present study, the chromosomal distribution and frequency of transcriptionall ...

Abstract:
... Adverse effects of gibberellin applications on pear trees after frost such as small fruit size, abnormal fruit shape and poor return bloom are often attributed both to the sole use of GA3 and its overdose. It is unclear whether protection against spring frosts before flower opening is more efficient when GA is applied directly after frost, i.e. before flower opening, or at full bloom or both. In A ...

Abstract:
... The New Word screwworm, Cochliomyia hominivorax (Coquerel 1858) (Diptera: Calliphoridae), is one of the most important insect pests of livestock in the Neotropical region. In this work, polymerase chain reaction-restriction fragment length polymorphism of mitochondrial DNA (mtDNA) was used to study the diversity and population structure of seven geographically distinct populations of C. hominivora ...

Abstract:
... Crinipellis perniciosa causes a serious disease of cacao known as witches' broom (WB). Heritable resistance to witches' broom has been used in cacao improvement programs. 'SCA6' and 'SCA12' are highly resistant and are the most commonly used parents in the breeding schemes. However, SCA hybrids are not resistant to witches' broom in all production areas. Presumably, different populations of C. per ...

Twenty-one Citrus tristeza virus (CTV) isolates from India were characterized, using genotype-specific multiple molecular markers (MMM) from the 54′-terminal region and two other overlapping primer pairs (CN487/489 and CN488/491) from ORF1a (697–1484 nucleotides (nt)). The 5′-terminal genotype-specific primer pairs amplified about 500 bases from the 5′-end of the CTV genomic RNA (gRNA). With the t ...
