Here, we describe two members of the Arabidopsis (Arabidopsis thaliana) Yellow Stripe-Like (YSL) family, AtYSL1 and AtYSL3. The YSL1 and YSL3 proteins are members of the oligopeptide transporter family and are predicted to be integral membrane proteins. YSL1 and YSL3 are similar to the maize (Zea mays) YS1 phytosiderophore transporter (ZmYS1) and the AtYSL2 iron (Fe)-nicotianamine transporter, ...

cDNA clones for ascorbate oxidase were isolated from a cDNA library made from cucumber (Cucumis sativus) fruit mRNA. The library was screened with synthetic oligonucleotides that encode the NH2-terminal sequence of this enzyme. Nucleotide sequence analysis of the cloned cDNA inserts revealed a 1761-base-pair open reading frame that encoded an NH2-terminal signal peptide of 33 amino acids and a ...

PREMISE OF THE STUDY Herbarium specimens may provide a record of past environmental conditions, including heavy metal pollution. To explore this potential, we compared concentrations of copper, lead, and zinc in historical and new collections from four sites in Rhode Island, USA. METHODS We compared historical specimens (1846 to 1916) to congener specimens collected in 2015 at three former in...

miR408 is highly conserved among different plant species and targets transcripts encoding copper-binding proteins. The function of miR408 in reproductive development remains largely unclear despite it being known to play important roles during vegetative development in Arabidopsis. Here, we show that transgenic Arabidopsis plants overexpressing MIR408 have altered morphology including significa...

BACKGROUND Thlaspi caerulescens is a natural selected heavy metal hyperaccumulator that can not only tolerate but also accumulate extremely high levels of heavy metals in the shoots. Thus, to identify the transportors involved in metal long-distance transportation is very important for understanding the mechanism of heavy metal accumulation in this hyperaccumulator. METHODOLOGY/PRINCIPAL FIND...

Almond red leaf blotch is the most important fungal disease that is caused by the fungus Polystigma amygdalinum. Symptoms depending on the cultivar almond trees can be seen almost all year. In this study the effect of 5 fungicides (Copper oxychloride  2000 µg/ml, Bordofix 2000 µg/ml, Mancozeb 200 µg/ml, Bordo Compound 10000 µg/ml, Triforin 300 µg/ml with rep.control) was examined in a randomize...
