Intermediate fertile Triticum aestivum （＋）Agropyron elongatum somatic hybrids are generated by low doses of UV irradiation

We report the production and characterization of somatic hybrids between Triticum aestivum L. and Agropyron elongatum (Host) Nevishi (the synonym is Thinopyrum ponticum). Asymmetric protoplast fusion was performed between Agropyron elongatum protoplasts irradiated with a low UV dose and protoplasts of wheat taken from nonregenerable suspension cultures. More than 40 green plantlets were obtained from 15 regenerated clones and one of them produced seeds. The phenotypes of the hybrid plants and seeds were intermediate between wheat and Agropyron elongatum. All of the regenerated calli and plants were verified as intergeneric hybrids on the basis of morphological observation and analysis of isozyme, cytological, 5SrDNA spacer sequences and random amplified polymorphic DNA (RAPD). RFLP analysis of the mitochondrial genome revealed evidence of random segregation and recombination of mtDNA.     

雀稗属花粉形态及其多萌发孔现象

在广东广泛收集禾本科雀稗属的基础上,观察了雀稗属（Paspalum)9个种及其类群的花粉形态。其花粉一般为球型,平均直径在34－50um之间,花粉表面纹饰一般为疣状突起或皱波状。在四倍体的台湾雀稗（P.formosanum),双穗雀稗（P.paspaloides),雀稗（P.thunbergii),两耳草（P.conjugatum),圆果雀稗（P.orbiculare),长叶雀稗（P.longifolium)和一个十倍体的南雀稗（P.commersonii)的一个类群上发现了禾本科罕见的花粉多萌发孔现象。
