To investigate the regulation of genes encoding CAB proteins in cotton (Gossypium hirsutum) and identify potentially useful promoters, we determined the structure and expression of two genes (Lhcbl*Z and Lhcb3*l) encoding type I and type 111 proteins of the LHCII subfamily (Table I). Northern analyses of the gene expression pattem in cotton demonstrated substantial LHCII transcript accumulation...

In this paper the current state of knowledge of the replication of cauliflower mosaic virus (CaMV) is reviewed and the DNA intermediates and enzymes involved in replication are discussed. Based on this information a model for the replication complex is developed. In this model it is suggested that replication complexes resemble virus particles and that, in their assembly, there are close intera...

trr14 is a novel protein important in trehalose (α-d-glucosyl-[1,1]-α-d-glucopyranoside) signaling in arabidopsis. in this research, we provided evidences to demonstrate that trr14 plays role in arabidopsis responses to salt and drought stress. the transgenic arabidopsis plants over-expressing trr14 under the control of camv 35s promoter were generated. transformed lines showed higher transcrip...

Scientific achievement in molecular biology and genetic engineering have made it possible to create new methods of selection k that are based on genome modification. Todays, more genetically modified plants being intensively tested the field, but their influence has not yet been fully studied environment, biodiversity, human health, animal body.

Developing transgenic resistance in monocotyledonous crops against pathogens remains a challenging area of research. Sugarcane mosaic virus (SCMV) is a serious pathogen of many monocotyledonous crops including sugarcane. The objective of present study was to analyze transgenic expression of hairpin RNA (hpRNA), targeting simultaneously CP (Coat Protein) and Hc-Pro (helper component-proteinase) ...

• An effective transformation method is described for Medicago truncatula A17, verifying its suitability as a model legume for functional genomics. • Media and culture methods are detailed that yielded an average frequency of 35% for recovery of transgenic shoots from cotyledonary node explants and 39% for root induction and regeneration of entire plants from 419 phosphinothricinresistant shoot...

Arundo donax L. is a promising biofuel feedstock in the Mediterranean region. Despite considerable interest in its genetic improvement, Arundo tissue culture and transformation remains arduous. The authors developed methodologies for cell- and tissue culture and genetic engineering in Arundo. A media screen was conducted, and a suspension culture was established using callus induced from stem a...

Abstract Diseases caused by bacteria are an important and widespread constraint, occurring in almost all crops, including vegetables, pulses, cereals, ornamentals, fruit forages. Although several strategies have been developed to obtain disease resistance plants using genetic engineering, few studies effectively demonstrated the control of bacterial diseases. It has previously reported that a g...
