Extensive genetic variations of low-molecular-weight glutenin subunits (LMW-GS) and their coding genes were found in the wild diploid A- and D-genome donors of common wheat. In this study, we reported the isolation and characterization of 8 novel LMW-GS genes from Ae.longissima Schweinf. & Muschl., a species of the section Sitopsis of the genus Aegilops, which is closely related to the В genome of common wheat. Based on the N-terminal domain sequences, the 8 genes were divided into 3 groups. A consensus alignment of the extremely conserved domains with known gene groups and the subsequent cluster analysis showed that 2 out of the 3 groups of LMW-GS genes were closely related to those from the В genome, and the remaining was related to those from A and D genomes of wheat and Ae. tauschii. Using 3 sets of gene-group-specific primers, PCRs in diploid, tetraploid and hexaploid wheats and Ae. tauschii failed to obtain the expected products, indicating that the 3 groups of LMW-GS genes obtained in this study were new members of LMW-GS multi-gene famailies. These results suggested that the Sitopsis species of the genus Aegilops with novel gene variations could be used as valuable gene resources of LMW-GS. The 3 sets of group-specific primers could be utilized as molecular markers to investigate the introgression of novel alien LMW-GS genes from Ae. longissima into wheat.

Three low-molecular-weight glutenin subunit (LMW-GS) genes, designated LMW-Tdl, LMW-Td2 and LMW-Td3, were isolated from wild emmer wheat (Triticum dicoccoides), which is the tetraploid progenitor of common wheat (T. aestivum). The complete nucleotide sequence lengths of LMW-Td1, LMW-Td2 and LMW-Td3 are 858, 900 and 1062 bp, respectively. LMW-Td1 and LMW-Td3 can encode proteins with 284 and 352 amino acid residues, respectively, whereas LMW-Td2 is a putative pseudogene due to the presence of 3 inframe stop codons in its C-terminal domain. The deduced protein sequences of the 3 genes share the same typical polypeptide structures with known LMW-GS genes containing 8 cysteines in the mature protein domains. LMW-Td1 was clearly distinguished from all known LMW-GS genes, and considered as a novel LMW-GS gene. Two hydrophobic motifs (i.e. PIIIL and PVIIL) were observed in the repetitive domain of LMW-Td3. Sequence comparison indicates that sequences of the 3 LMW-GS genes from this study are strongly similar to known LMW-GS genes. Our phylogenetic analysis suggests that LMW-Td1 and LMW-Td2 are homologous with genes on chromosome 1A, and LMW-Tdl is closely related to genes on chromosome 1B.

Barley stripe mosaic virus (BSMV) is an established and extensively used virus-induced gene silencing (VIGS) vector for gene function analysis in monocots. However, the phenotypes generated by targeted gene silencing may be affected or masked by symptoms of BSMV infection. To better understand the potential effects of BSMV-VIGS in hulless barley (Hordeum vulgare var. nudum), the accumulation pattern of BSMV and its impacts on vegetative growth and water status were investigated. The results indicated that the vegetative growth of infected plants was significantly and continuously impacted by BSMV from 10 to 40 days post inoculation (dpi). When the accumulation of BSMV was extremely high (7 to 11 dpi), infected plants displayed twisted leaf tips with an increased water lose rate (WLR) and decreased water content (WC). Virus accumulation declined and stabilized after 25 dpi, at this stage, the WLR and WC were unaffected in the infected plants. The efficiency of VIGS was tested by the silencing of Phytoene desaturase (PDS). RT-qPCR indicated that BSMV-VIGS can be sustained with good efficiency for up to 40 dpi under an altered condition with lower temperature (22 ±1°C) and higher relative humidity (70 ±10%). It was concluded that 25 to 40 dpi was the appropriate time zone for drought-related gene analysis by BSMV-VIGS under such condition.
