“…However, the pollen-speci®c proteins have characteristic changes in otherwise conserved amino acids in the kinase domain that are not found in SERK genes (Muschietti et al 1998), and lack other SERK-speci®c features (ZIP, SPP, C). Five LRRs are also found in the closest overall relative of SERK genes, a sorghum protein with high expression levels in mesophyll cells (Annen and Stockhaus 1999). However, again two SERK-speci®c features (SPP, C) are missing, while the number of leucine residues in the putative ZIP domain is reduced from four to three.…”

Genes encoding two novel members of the leucine-rich repeat receptor-like kinase (LRR-RLK) superfamily have been isolated from maize (Zea mays L.). These genes have been named ZmSERK1 and ZmSERK2 since features such as a putative leucine zipper (ZIP) and five leucine rich repeats in the extracellular domain, a proline-rich region (SPP) just upstream of the transmembrane domain and a C-terminal extension (C) after the kinase domain identify them as members of the SERK (somatic embryogenesis receptor-like kinase) family. ZmSERK1 and ZmSERK2 are single-copy genes and show 79% identity among each other in their nucleotide sequences. They share a conserved intron/exon structure with other members of the SERK family. In the maize genome, ZmSERK1 maps to position 76.9 on chromosome arm 10L and ZmSERK2 to position 143.5 on chromosome arm 5L, in regions generally not involved in duplications. ZmSERK1 is preferentially expressed in male and female reproductive tissues with strongest expression in microspores. In contrast, ZmSERK2 expression is relatively uniform in all tissues investigated. Both genes are expressed in embryogenic and non-embryogenic callus cultures.

“…The receptor kinase associated with cotton fiber development has recently been cloned (Li et al 2005). The receptor kinases HAESA and SbRLK1 have been described in different systems (Annen and Stockhaus 1999;Jinn et al 2000). The Arabidopsis CLAVATA2 gene encodes a receptor-like protein required for the stability of the CLAVATA1 receptor-like kinase (Jeong et al 1999).…”

Evidence for the presence of non-receptor protein tyrosine kinases in algal cells

Two orders of green alga (Cladophorales and Charales) were investigated for the presence of protein tyrosine kinase activity. Proteins of 70 and 85 kDa were found to be tyrosine phosphorylated in Cladophora fracta, with an additional phosphorylated band evident at the 120-kDa region in Chara vulgaris, suggestive of the presence of putative tyrosine kinase activity in these algal species. A 70-kDa protein was immunoprecipitated from both species using a polyclonal antibody against non-receptor protein tyrosine kinase Syk. The protein was found to be phosphorylated on tyrosine, which was prevented upon pretreatment of algal cells with piceatannol. The extent of phosphorylation directly correlated with algal growth, suggesting a link between Syk kinase activity and growth signaling. These observations supported the presence of Syk-like kinase in the green algal species, which could have critical role in the algal growth and development.

“…However, studies of ERECTA gene family other than Arabidopsis plants are still limited. Involvement of an ER homolog in Sorghum bicolor, SbRLK1 in the regulation of specific processes in the mesophyll cells was reported [19]. In Zea mays, ERECTA genes play a role in controlling plant growth, organ size and yield of plants [20].…”

Modification of soybean growth and abiotic stress tolerance by expression of truncated ERECTA protein from Arabidopsis thaliana

ERECTA gene family encodes leucine-rich repeat receptor-like kinases that control major aspects of plant development such as elongation of aboveground organs, leaf initiation, development of flowers, and epidermis differentiation. To clarify the importance of ERECTA signaling for the development of soybean (Glycine max), we expressed the dominant-negative ERECTA gene from Arabidopsis thaliana that is truncated in the kinase domain (AtΔKinase). Expression of AtΔKinase in soybean resulted in the short stature, reduced number of leaves, reduced leaf surface area and enhanced branching in the transgenic plants. The transgenic AtΔKinase soybean plants exhibited increased tolerance to water deficit stress due to the reduction of total leaf area and reduced transpiration compared to the wild-type plants. Production of seeds in AtΔKinase lines was higher compared to wild type at regular conditions of cultivation and after exposure to drought stress. Transgenic seedlings expressing AtΔKinase were also able to withstand salt stress better than the wild-type. Established results demonstrated the significance of native soybean genes (GmER and GmERL) in development and stress response of soybean, and suggested that the truncated ERECTA gene of Arabidopsis thaliana can be used to manipulate the growth and stress response of different crop species.
