Alternative Rooting Methods for Medicinal Cannabis Cultivation in Denmark-Preliminary Results.

L. is typically propagated through micropropagation or vegetative cuttings, but the use of root-inducing hormones, such as indole-3-butyric acid (IBA), is not allowed for growing medicinal cannabis in Denmark. This study examined alternative rooting treatments, including inoculation, water-only as well as IBA treatments, in eight cannabis cultivars.

Sequence of a complete chicken BG haplotype shows dynamic expansion and contraction of two gene lineages with particular expression patterns.

Many genes important in immunity are found as multigene families. The butyrophilin genes are members of the B7 family, playing diverse roles in co-regulation and perhaps in antigen presentation. In humans, a fixed number of butyrophilin genes are found in and around the major histocompatibility complex (MHC), and show striking association with particular autoimmune diseases.

Evolution of MHC class I in the order Crocodylia.

The major histocompatibility complex (MHC) is a dynamic genomic region with an essential role in the adaptive immunity of jawed vertebrates. The evolution of the MHC has been dominated by gene duplication and gene loss, commonly known as the birth-and-death process. Evolutionary studies of the MHC have mostly focused on model species.

Two mannose-binding lectin homologues and an MBL-associated serine protease are expressed in the gut epithelia of the urochordate species Ciona intestinalis.

The lectin complement pathway has important functions in vertebrate host defence and accumulating evidence of primordial complement components trace its emergence to invertebrate phyla. We introduce two putative mannose-binding lectin homologues (CioMBLs) from the urochordate species Ciona intestinalis. The CioMBLs display similarities with vertebrate MBLs and comprise a collagen-like region, alpha-helical coiled-coils and a carbohydrate recognition domain (CRD) with conserved residues involved in calcium and carbohydrate binding.

Structures of an MHC class I molecule from B21 chickens illustrate promiscuous peptide binding.

Little is known about the structure of major histocompatibility complex (MHC) molecules outside of mammals. Only one class I molecule in the chicken MHC is highly expressed, leading to strong genetic associations with infectious pathogens. Here, we report two structures of the MHC class I molecule BF2*2101 from the B21 haplotype, which is known to confer resistance to Marek's disease caused by an oncogenic herpesvirus.
