The study presented here was conducted to assess the impacts of various water conditions on the functional aspects and genetic diversity of oak species. We compared four Quercus species [Quercus petraea ssp. iberica (Stev.), Q. macranthera ssp. macranthera (K.Koch) Menitsky, Q. castaneifolia C.A.Mey., Q. robur ssp. pedunculiflora (K.Koch) Menitsky] in different sites of Azerbaijan. Thus, five functional traits (relative water content (RWC), water content (WC), leaf mass per unit area (LMA), specific leaf area (SLA), and succulence (S) related to drought tolerance were measured. Then, cluster analysis based on these functional traits was conducted, and the Euclidean genetic distance index was determined. As the temperature increases and the amount of precipitation decreases, plants are exposed to drought stress, which is accompanied by a decrease in RWC, WC, SLA and S. In contrast, an increase in LMA was observed. This response of the plant to changing environmental conditions reflects the activation of a protective mechanism; the plant is fighting for survival. The conducted analyses reveal significant genetic diversity among oak genotypes, which is formed under the influence of ecological adaptation, geographical distribution, and evolutionary processes.

There are two types of this disease: X-linked AGM (XLA) and autosomal forms. X-linked agammaglobulinemia results from a mutation in the gene for Bruton’s tyrosine kinase (BTK), found on the X chromosome. Mutations in BTK result in lack of mature B-cells and immunoglobulins of all classes. There are 8 types of autosomal forms which are reflected in different defective genes. 7-year-old male patient at the age of 1 - 6, was encountered the recurrent broncho-pulmonary and gastro-intestinal infections, furunculosis and recurrent otitis. Also, because of the strain, pain and swelling on the 4th finger of the right hand it was suspected that the patient had rheumatoid arthritis. On immunological investigation, we have found out of absent of B lymphocyte. Level of IgG was 10 times less; IgA, IgM and IgE levels were 3 to 8 times less than the norm. Quantity of T-lymphocytes: absolute number of CD4+ lymphocytes increased, CD3+ and CD8+ lymphocytes were also high. Phagocyte activity in NBT, absolute number of NK cells and IRI index were 2 times lower than the norm. Genetically analysis has discovered the presence of abnormal homozygous BLNK gene.
