Glutamyl-tRNA reductase1 (HEMA1) and ferrochelatase1 (FC1) are both expressed in response to salt stress in the biosynthetic pathway of tetrapyrroles. Peanut (Arachis hypogaea L.) HEMA1 and FC1 were isolated by RT-PCR. The amino acid sequence encoded by the two genes showed high similarity with that
We have identified a transcript derived fragment (TDF) corresponding to SGT1 in a study of differential gene expression on the resistant wild peanut, Arachis diogoi, upon challenge from the late leaf spot pathogen, Phaeoisariopsis personata, and cloned its full-length cDNA followed by subsequent
Late embryogenesis abundant (LEA) proteins are a group of hydrophilic proteins, which accumulate in plants under varied stress conditions like drought, salinity, extreme temperatures and oxidative stress suggesting their role in the protection of plants against these stresses. A transcript derived
A gene from groundnut (Arachis hypogaea) coding for stilbene synthase was transferred together with a chimaeric kanamycin resistance gene. It was found to be rapidly expressed after induction with UV light and elicitor in tobacco cells (Nicotiana tabacum). Comparative studies of stilbene synthase
Zamia furfuracea (Zamiaceae) is native of coastal Mexico. It is a popular houseplant and easy to grow outdoors in warm climates. In November 2005, a plant of Z. furfuracea, originally from Texas, was received at the Division of Plant Industry in Gainesville, FL. The plant had numerous chlorotic
Polyamines play an important role in stress response. In the pathway of polyamines synthesis, S-adenosylmethionine decarboxylase (SAMDC) is one of the key enzymes. In this study, a full length cDNA of SAMDC (AhSAMDC) was isolated from peanut (Arachis hypogaea L.). Phylogenetic analysis revealed high
A virus disease of peanut (groundnut, Arachis hypogaea L.), characterized by necrosis of the stem and terminal leaflets followed by death, caused severe crop losses in Andhra Pradesh, India during the rainy season of the year 2000. The disease was referred to as peanut stem necrosis disease (PSND).
Fertile transgenic plants of peanut (Arachis hypogaea L.) cv. TMV-2 expressing tobacco chitinase and neomycin phosphotransferase (npt II) genes were generated using an Agrobacterium tumefaciens (LBA4404/pBI121-pBTex)-mediated transformation system. A tissue culture-independent method wherein embryo
The tropical armyworm, Spodoptera litura (F.) (Lepidoptera: Noctuidae), is an important pest of tobacco, Nicotiana tabacum L. (Solanales: Solanaceae), in South China that is becoming increasingly resistant to pesticides. Six potential trap crops were evaluated to control S. litura on tobacco. Castor
Safflower, Carthamus tinctorius L. (Asteraceae), is extensively cultivated in India, China, and other parts of Asia for edible oil, dyeing agent, and its medicinal value. In 2003, safflower entry (NARI-6) in the All-India Coordinated Research Project on Oilseeds (Safflower) grown in the experimental
Guizotia abyssinica (L.f.) Cass. (niger), an important oil seed crop grown in India, is used in foods, paints, soaps, and as an illuminant. During a survey conducted in 2004 to monitor Tobacco streak virus (TSV) in Helianthus annuus L. (sunflower) and Arachis hypogaea L. (groundnut), typical
Thripenema fuscum n. sp., a parasite of the tobacco thrips, Frankliniella fusca, is described and illustrated from material collected from peanut (Arachis hypogaea) in Marianna, Florida. Thripenema fuscura can be distinguished from all other previously described Thripenema spp. by the dorsal
Two different genes encoding class II chitinases from peanut (Arachis hypogaea L. cv. NC4), A.h.Chi2;1 and A.h.Chi2;2, have been cloned. In peanut cell suspension cultures, mRNA levels of A.h.Chi2;2 increased after ethylene or salicylate treatment and in the presence of conidia from Botrytis
The major cationic peanut (Arachis hypogaea) peroxidase, secreted into the extracellular space, is a glycoprotein with three N-linked glycans (polysaccharides) which are connected to the peptide backbone at Asn-60, Asn-144 and Asn-185. In this report, a C-terminal histidine-tagged cationic peanut
Mitogen-activated protein kinase cascade plays a very important role in plant signal transduction mechanism. A full length cDNA of 1,514 bp length, corresponding to a mitogen-activated protein kinase gene was cloned from peanut (Arachis hypogaea). Based on its high homology with Arabidopsis AtMPK3,
