Cytochrome P450 proteins belong to one of the largest families enzyme in plants and play important roles plant growth development stress response. In our previous studies, a cytochrome gene, GhCYP94C1 (cytochrome 94C1), was functionally characterized as positive regulator seed germination, main root elongation early flowering. However, whether gene has other potential functions rem...

Mitogen-activated protein kinase (MAPK) cascades are rapidly activated upon plant recognition of invading pathogens. Here, we describe the use of virus-induced gene silencing (VIGS) to study the role of candidate plant MAP kinase kinase kinase (MAPKKK) homologs of human MEKK1 in pathogen-resistance pathways. We demonstrate that silencing expression of a tobacco MAPKKK, Nicotiana Protein Kinase ...

In the yeast two-hybrid screening of plant factors interacting with tobacco mosaic virus (TMV) RNA-dependent RNA polymerase (RdRp), we found a protein containing a RING finger motif in tobacco (Nicotiana tabacum) and designated it as TARF (TMV-associated RING finger protein). TARF is a homologue of a Lotus japonicus RING finger protein (LjnsRING) involved in the symbiotic interaction between L....

Recently, a large number of long noncoding RNAs (lncRNAs) have emerged as important regulators of many biological processes in animals and plants. However, how lncRNAs function during plant DNA virus infection is largely unknown. We performed strand-specific paired-end RNA sequencing of tomato samples infected with Tomato yellow leaf curl virus (TYLCV) with three biological replicates. Overall,...

Characterizing the molecular mechanism involved in nonhost disease resistance is important to understand the adaptations of plant-pathogen interactions. In this study, virus-induced gene silencing (VIGS)-based forward genetics screen was utilized to identify genes involved in nonhost resistance in Nicotiana benthamiana. Genes encoding ribosomal proteins, RPL12 and RPL19, were identified in the ...

Nucleolar proteins play important roles in plant cytology, growth, and development. Fibrillarin2 is a nucleolar protein of Nicotiana benthamiana (N. benthamiana). Its cDNA was amplified by RT-PCR and inserted into expression vector pEarley101 labeled with yellow fluorescent protein (YFP). The fusion protein was localized in the nucleolus and Cajal body of leaf epidermal cells of N. benthamiana....

The improvement of the agricultural and wine-making qualities of the grapevine (Vitis vinifera) is hampered by adherence to traditional varieties, the recalcitrance of this plant to genetic modifications, and public resistance to genetically modified organism (GMO) technologies. To address these challenges, we developed an RNA virus-based vector for the introduction of desired traits into grape...

Light is an important environmental signal that governs plant growth, development, and metabolism. Constitutive photomorphogenic 1 (COP1) a light signaling component plays vital role in responses. We isolated the COP1 gene (LoCOP1) from petals of Lilium ‘Siberia’ investigated its function. The LoCOP1 protein was found to be most similar Apostasia shenzhenica COP1. factor located nucleus played ...
