Gene families from the Arabidopsis thaliana pollen coat proteome.
The pollen extracellular matrix contains proteins mediating species specificity and components needed for efficient pollination. We identified all proteins >10 kilodaltons in the Arabidopsis pollen coating and showed that most of the corresponding genes reside in two genomic clusters. One cluster encodes six lipases, whereas the other contains six lipid-binding oleosin genes, including GRP17, a...
متن کاملPhylogenetic analysis of two Iranian grapevine virus A isolates using coat protein gene sequence
Symptomatic grapevine samples were collected from vineyards in Zanjan province to detect Grapevine virus A. Total RNA was extracted from symptomatic leaf samples and subjected to cDNA synthesis using random hexamer primers. Then, a DNA fragment around 800 bp including the complete coat protein (CP) gene was amplified from nine out of 57 samples by polymerase chain reaction (PCR) using specific ...
متن کاملCharacterization of Coat Protein Gene of Cucumber Mosaic Virus Isolates in Iran
Background: Cucumber mosaic virus (CMV) from the Bromoviridae family, is one of the most widespread plant viruses in the world. Objectives: In the present study tomato fields in Guilan, Isfahan, Khorasan Razavi, Khuzestan and Tehran provinces were surveyed to determine the presence of CMV subgroups during 2011-2012. Materials and Methods: Out of 305 symptomatic leaf samples ...
متن کاملA pollen coat protein, SP11/SCR, determines the pollen S-specificity in the self-incompatibility of Brassica species.
Many flowering plants have evolved self-incompatibility (SI) systems to prevent inbreeding. In the Brassicaceae, SI is genetically controlled by a single polymorphic locus, termed the S-locus. Pollen rejection occurs when stigma and pollen share the same S-haplotype. Recognition of S-haplotype specificity has recently been shown to involve at least two S-locus genes, S-receptor kinase (SRK) and...
متن کاملNucleotide sequence of the bean leafroll luteovirus coat protein gene.
Purified BLRV RNA was converted to cDNA and cloned into pT7T3 19U phagemid. The nucleotide sequence of a putative bean leafroll luteovirus coat protein gene was determined from the clones pBL9, pBL29 and pBL32 by the chain termination method (1). Sequence analysis reveals a 588 bp open reading frame and an internal 426 bp ORF (Fig. 1). The large ORF is equivalent to a protein of Mr 21.98 kDa, t...
