جُمعت عينات من نبات القبّار Capparis spinosa من (6) مناطق توزعت في محافظتي حلب و اللاذقية. تمت دراسة التباينات باستخدام تقانة الـ AFLP بهدف تحديد الهوية الوراثية للطرز المدروسة باستخدام (3) بادئات أظهرت مكاثرة للـDNA ، و حُسب معامل الاختلاف و معامل التنوّع الوراثي، و أنشئت شجرة القرابة الوراثية، و أُجري تحليل المكونات الأساسية (A.C.P.)، و حُسبت F– الإحصائية، فأظهرت هذه الدراسة النتائج التالية:
- تأكيد وجود عدد معين من الألليلات (الحزم) التخصصية أو المميزة Discriminate خاصة بكل محافظة،
- دلّ هذا على وجود عزل وراثي و تكاثري محدد وعائق للتدفق المورثي gene flow بين المحافظتين.
- تميّزت اللاذقية بمعدّل تغايرية (0.486) أعلى بقليل من حلب (0.481)، و متوسط معامل التنوّع الوراثي على مستوى البادئات و الأفراد (0.677) في حلب أعلى بقليل من اللاذقية (0.653)، و مستوى المجتمعات المختلفة متقاربة جدا" (0.759) في حلب (0.760 ) في اللاذقية, يُفسّر ذلك وفق ظاهرتي الألليلات الصامتة و التخصصيّة التي تُعزى لحدوث الطفرة بالحذف، و أيضاً لتأثيرات اصطفائية مختلفة و لنظم التكاثر في المحافظتين.
- أكبر قيمة للبعد الوراثي في حلب (0.381) بين (الضاحية و الشيخ سعيد)، و أكبر قيمة للبعد الوراثي في اللاذقية (0.38) بين (العمرونية و جبلة)، بينما أكبر قيمة تشابه (0.637) بين (الشيخ سعيد و تركمان بارح) في حلب، و (0.675) بين (وطى ديرزينون و جبلة) في اللاذقية، و تباين متدرج بين هذه القيم المحسوبة.
- أظهرت دراسة F- الإحصائية تأثير عامل القرابة في بعض المجتمعات و برز ذلك أكثر أهمية و أكبر نسبياً في حلب منه في اللاذقية, يدّل ذلك على أن نظام التكاثر أكثر انغلاقاً في حلب و يُعزى للتكاثر عن طريق الجوار أو التلقيح الذاتي، و هذا ما أظهر تباينا" وراثيا عالياً بين مجتمعاتها بالمقارنة مع مجتمعات اللاذقية.
- سمحت هذه الدراسة بتحديد بادئات يمكن استخدامها كمؤشرات جزيئية في برامج تحسين القبّار كنبات طبي و غذائي, و أظهرت هذه التقانة كفاءة عالية في دراسة علاقات القرابة بين المجتمعات في المحافظتين.
Samples of Capparis spinosa plant were collected from 6 sites in Aleppo and Lattakia
provinces. The genetic variations were studied using the AFLP technique in order to determine the
genotypes of the studied types using 3 primers, which showed amplification. Statistical analyses
were conducted using the dissimilarity coefficient and genetic diversity coefficient. The A.C.P. and
the statistical -F were calculated, and the similarity dendrogram was constructed. The results
showed the following:
The presence of a certain number of specific alleles (descriminates) for each province.
The presence of genetic and reproductive isolation deterrent to gene flow between the two
provinces.
The heterozygoty average was a little higher in Lattakia (0.486) than in Aleppo (0.481). The
mean of genetic diversity coefficient of primers and individuals was a little higher in Aleppo
(0.677) than in Lattakia (0.653). The population mean was very close: (0.759) in Aleppo and
(0.760) in Lattakia. This may be explained on the basis of silent and specific alleles due to deletion
mutations, different selective effects as well as the reproduction system in the two cities.
The greatest genetic distance in Aleppo was (0.381) noted between (Al Dahea and Al Shekh
saaed), and in Lattakia (0.38) noted between (Al Amroniah and Jabla). However, the greatest
genetic similarity in Aleppo was (0.637) noted between (Al Shekh Saaed and Turkman Bareh), and
in Lattakia (0.675) noted between (Wata Deirzenon and Jabla). The variation between these values
was graduated.
The study of statistical –F showed the effect of the similarity factor in some populations.
This was more significant in Aleppo than in Lattakia, which indicates that the reproduction system
is more closed in Aleppo, and this refers as well to inbreeding or self pollination which showed
high genetic variations in these populations when compared with Lattakia.
The results of this study helped in determining primers that can be used as molecular
markers in a breeding program for Capparis spinosa as a medicinal plant. This technique showed
high efficiency in studying the similarity relationships between these two cities.
