Olive tree (Olea europaea) pollen is a main cause of allergy in Mediterranean areas and North America. A novel allergen, Ole e 11, has been detected by proteomic techniques. Protein bands binding IgE from allergic sera were excised from a 2D electrophoresis gel and analysed by Edman degradation and
Tapiscia sinensis (Tapisciaceae) has been proven to be a functional androdioecious species with both male and hermaphroditic individuals, and pollen viability of male is far higher than that of hermaphrodites. To better understand the causes of the low pollen viability in hermaphroditic flowers,
Mlo gene encodes a plant-specific seven-transmembrane domain protein involved in a variety of cellular processes. In this study, a novel Mlo gene from rubber tree (Hevea brasiliensis), designated HbMlo1, was cloned by RT-PCR in rubber tree. The ORF of HbMlo1 was 1551bp in length, encoding a putative
Machilus yunnanensis Lecomte is an important Chinese timber species in the family Lauraceae, subclass Magnoliidae. To understand the genetic and molecular basis of flowering in M. yunnanensis, we applied RNA-seq for transcriptome analysis of young and mature flowers and compared these with the
cgMT1 is a metallothionein (MT)-like gene that was isolated from a cDNA library of young nitrogen-fixing nodules resulting from the symbiotic interaction between Frankia spp. and the actinorhizal tree Casuarina glauca. cgMT1 is highly transcribed in the lateral roots and nitrogen-fixing cells of
Cultured guard cell protoplasts (GCP) of tree tobacco (Nicotiana glauca) comprise a novel system for investigating the cell signaling mechanisms that lead to acquired thermotolerance and thermoinhibition. At 32 degrees C in a medium containing an auxin (1-naphthaleneacetic acid [NAA]) and a
Mildew resistance locus O (Mlo) gene was first found in barley as a powdery mildew susceptibility gene, and recessive mlo alleles confer durable resistance to barley powdery mildew. To identify candidate Mlo susceptibility genes in rubber tree, HbMlo12 was cloned from
Allocasuarina verticillata is an actinorhizal tree that lives in symbiotic association with a nitrogen fixing actinomycete called Frankia. In the search for promoters that drive strong constitutive expression in this tropical tree, we studied the organ specificity of four different constitutive
Arabidopsis thaliana SAG12, a senescence-specific gene encoding a cysteine protease, is widely used as a molecular marker for the study of leaf senescence. To date, its potential orthologues have been isolated from several plant species such as Brassica napus and Nicotiana tabacum. However, little
Our previous studies indicated that high light induced significant photoinhibition of photosystem I (PSI) in the shade-establishing tree species Psychotria henryi. However, the underlying mechanism has not been fully clarified. In the present study, in order to investigate the mechanism of PSI
Community-level mass flowering, known as general flowering, which occurs in South-East Asia at supra-annual irregular intervals, is considered a particularly spectacular phenomenon in tropical ecology. Recent studies have proposed several proximate factors inducing general flowering, such as drought
Eucalyptus camaldulensis is a tree species in the Myrtaceae that exhibits extremely high resistance to aluminum (Al). To explore a novel mechanism of Al resistance in plants, we examined the Al-binding ligands in roots and their role in Al resistance of E. camaldulensis. We identified a novel type
In plants, brassinosteroid biosynthesis and metabolism genes affect endogenous brassinosteroid metabolic processes as well as stem and root growth. However, there is little information available regarding these genes in apple. In this study, 22 brassinosteroid biosynthesis and metabolism genes were
BACKGROUND
Members of major intrinsic proteins (MIPs) include water-conducting aquaporins and glycerol-transporting aquaglyceroporins. MIPs play important role in plant-water relations. The model plants Arabidopsis thaliana, rice and maize contain more than 30 MIPs and based on phylogenetic analysis
