The farnesyltransferase α-subunit (FTA) may be involved in the regulation of defence responses against pathogens plants. In this study, gene was amplified from Catharanthus roseus (CrFTA gene). cDNA found to 1 403 bp long, and encodes a putative protein 331 amino acids that contains conserved PPTA motif. phylogenetic analysis showed sequence CrFTA is most similar Coffea canephora. qRT-PCR assay...

In the last years, studies on captive greater flamingos have increased. Research on zoo animals is important to improve the knowledge on these species and to improve their ex-situ and in-situ conservation. The aim of the present study was to investigate the parental behaviour of a captive colony of greater flamingo hosted at Parco Natura Viva, an Italian zoological garden, to improve the knowle...

Substrate stratification is a new research area in which multiple substrates, or the same substrate with differing physical properties, are layered within container to accomplish production goal, such as decreasing water use, nutrient leaching, potentially reducing weed growth. Previous using pine ( Pinus sp.) bark screened ?1/2 3/4 inch reduced growth of bittercress Cardamine flexuosa ) by 80%...
