Abstract The zinc finger homeodomain (ZF-HD) genes belong to the homeobox gene family, playing critical roles in flower development and stress response. Despite their importance, however, to date there has been no genome-wide identification and characterization of the ZF-HD genes that are probably involved in stress responses in maize. In this study, 24 ZF-HD genes were identified, and their chromosomal locations, protein properties, duplication patterns, structures, conserved motifs and expression patterns were investigated. The results revealed that the ZF-HD genes are unevenly distributed on nine chromosomes and that most of these genes lack introns. Six and two ZF-HD genes have undergone… More >

Abstract Dehydrins or Group 2 Late Embryogenesis Abundant (LEA) proteins play an important role in the response and adaptation to different types of abiotic stresses such as droughts, high salinity and low temperatures. Using PCR techniques, we identified three gene fragments that encoded dehydrin-like proteins in three cactispecies Opuntia ficus-indica (OpfiDHN-like), Leuchtenbergia principis (LepDHN-like) and Mammillaria bombycina (MabDHN-like). Bioinformatic sequence analysis showed an identity between 96 and 97% with the Opuntia streptacantha dehydrin 1 (OpsDHN1) gene, demonstrating that the amplified fragments corresponded to dehydrin-like gene sequences, and that the designed oligonucleotides were effective for similar gene amplification in different cacti genera.… More >
