Phytochelatin synthase (PCS) is an enzyme involved in the synthesis of phytochelatins, cysteine-rich peptides which play a key role in heavy metal (HM) detoxification of plants. Mulberry (Morus L.), one of the most ecologically and economically important tree genera, has the potential to remediate

Fragaria (strawberry) and Rubus species (blackberry, wild blackberry, red raspberry and black raspberry) were thought to be infected with distinct isolates of Tobacco streak virus (TSV). Employing serology and nucleic acid hybridization it has been shown that these isolates form a cluster distinct

In 2006, primocane stunted growth and crumbly berry development were observed on 4-year-old Kiowa and Apache blackberry cultivars grown at the Chilton Research and Extension Center, Clanton, AL. Samples from affected plants were tested for virus infection by ELISA kits (Agdia, Inc., Elkhart, IN)

Heterotrimeric guanine-nucleotide-binding proteins (G-proteins) play key roles in responses to various abiotic stress responses and tolerance in plants. However, the detailed mechanisms behind these roles remain unclear. Mulberry (Morus alba L.) can adapt to adverse abiotic stress conditions;

Osmotin and osmotin-like proteins are stress proteins belonging to the plant PR-5 group of proteins induced in several plant species in response to various types of biotic and abiotic stresses. We report here the overexpression of tobacco osmotin in transgenic mulberry plants under the control of a

The dehydration responsive element binding (DREB) transcription factors have been reported to be involved in stress responses. Most studies have focused on DREB genes in subgroups A-1 and A-2 in herbaceous plants, but there have been few reports on the functions of DREBs from the A-3-A-6 subgroups

Desiccation tolerance is a complex phenomenon that depends on the regulated expression of numerous genes during dehydration and subsequent rehydration. Our previous study identified a chloroplast drought-induced stress protein (MaCDSP32) in mulberry, a thioredoxin (Trx) that is upregulated under

Mulberry crinkle leaf virus (MCLV) is a novel geminivirus recently identified from the woody plant mulberry (Morus alba L.). Little is known about the functions of the proteins encoded by the MCLV genome. Here, all the MCLV-encoded proteins were examined for the ability to suppress gene silencing by

The genus Morus consists of trees and shrubs, which are distributed in temperate and subtropical regions. Commonly known as mulberry, a few of the Morus species are valued for their foliage, which constitutes the chief feed for mulberry silkworms. Steroids and isoprenoid compounds present in the

In August of 2006, a new bacterial disease was noted in Hangzhou mulberry orchards of Zhejiang Province, China where bacterial wilt of mulberry caused by Ralstonia solanacearum was previously reported (3). In the summer, the disease caused severe wilt, especially on 1- or 2-year-old mulberry plants,

The Panel on Plant Health of EFSA conducted a pest categorisation of 17 viruses of Rubus L. that were previously classified as either non-EU or of undetermined standing in a previous opinion. These infectious agents belong to different genera and are heterogeneous in their biology. Blackberry

Following a request from the EU Commission, the Panel on Plant Health performed a pest categorisation of 17 viruses and viroids, herein called viruses, of Cydonia Mill., Malus Mill. and Pyrus L. determined as being either non-EU or of undetermined standing in a previous EFSA

Cryptococcus neofomans is an encapsulated yeast-like fungus that causes life-threatening infections, especially in immunosuppresive patients. C.neoformans infection is believed to be acquired via inhalation of aerosolized particles from the environment. Avian guano, decaying tree hollows and soil

Heterotrimeric guanine-nucleotide-binding proteins (G-proteins) consist of α, β and γ subunits and play important roles in response and tolerance to abiotic stresses in plants, but the function of the heterotrimeric G-protein β subunit in response to drought remains unclear. In the present study,
