[Pea (Pisum sativum) genes, participating in symbiosis with nitrogen-fixing bacteria. III. Study of the structure of the ENOD12 early nodulin gene for various types of peas using the polymerase chain reaction (PCR)]. / Geny gorokha (Pisum sativum), uchastvuiushchie v simbioze s azotfiksiruiushchimi bakteriami. II. Issledovanie struktury gena rannego nodulina ENOD12 dlia razlichnykh sortov gorokha s pomoshch'iu polimeraznoi tsepnoi reaktsii (PCR).

We have determined the length of early noduline gene ENOD12 in various varieties and lines of pea (Pisum sativum) using the polymerase chain reaction (PCR). It was demonstrated that promoter regions of ENOD12A and ENOD12B genes in line 2150 (Afghanistan) are longer than these in variety "Feltham first". The disparity is 14 bp. When studying these genes in 7 different lines and varieties of pea it was found that ENOD12A gene is more variable in size than the ENOD12B gene. We showed the possibility to analyze the heritage of ENOD12 gene's alleles by using the PCR method.
