“…Similarly to other chlorophyll mutants of rye the mode of inheritance of this feature was single-gene (NrLS- SON-EHLE 1913;BREWBAKER 1926;FIEDOROV eta/. 1971;HoPPE 1985;KuBICKA et al 1998;2000). On accoUnt of the fact that this type of chlorophyll change in rye had never been described in literature before, the gene determining the appearance of this feature was defined by the symbol tys after term transversal yellow stripes on leaves.…”

The lethal chlorophyll mutant is described in this work. It is characterized by irregular, transversal, yellow stripes of equal width on the leaf blade of seedlings. Those seedlings usually produced 2 leaves (though at times 3 or 4), however they did not propagate and some of them died out by the end of November. The way of inheritance of this trait was defined on the basis of segregation of plants with a normal green colour of leaves ( 4 91) and plants with yellow, transversal stripes on leaves (167) in the segregating population. The obtained segregation is close to the theoretical ratio 3: 1 which shows that the feature is determined by a recessive gene denoted by the •symbol tys (transversal, yellow stripes). The expression of gene tys was observed on the level of chloroplast ultrastructure in the shape of a reduction of the number of thylakoids and grana as well as lesser the net photosynthesis of intensity. Moreover, the tys gene caused a significant decrease of chlorophyll a and b content as well as a + b in leaves of the mutant in comparison with control. The chlorophyll mutant characterized above was first described in this work.

“…However, independently of the way the mutants were obtained the same genes were involved. For instance hs 1 and hs 2 mutants resulted from mutation of the same gene, marked as ync (KUBICKA et al 1998). Although these mutants were characterised by similar phenotypes, the expression of ync gene in hs 1 and hs 2 mutants was different on the level of chloroplast ultrastructure and chlorophyll (a and b] contents.…”

“…These changes are accompanied by disorganization of internal lamellar system in plastids. The bigger fragment of leaf changes colour the higher degree in plastid disorganization is seen (GABARA and KUBICKA 1991;KUBICKA et al 1986KUBICKA et al , 1998.…”

-Two groups of chlorophyll mutants of winter rye i.e. lethal and semilethal were compared in the present studies. Plants of the first group were characterized by pink orange or light violet colour of leaves at the seedlings stage. Plants with light green leaves, with yellow necrotic spots on leaves, or with white pattern and necrotic spots on leaves belonged to the second semilethal group. While plas-tids in pink and violet mutants were deprived of internal membrane organization in orange ones they had single thylakoids. In the second group of plants granal and intergranal thylakoids were present although the number of grana was reduced. The above changes in the plastid ultrastructure were accompanied by a lack of chlorophylls in pink, orange and light violet plants or strong reduction of both chlorophylls a and b in the remaining mutants. All the described features were inherited by single recessive genes.

Inbred lines from different varieties of cultivated plants characterized by a white yellow irregular pattern on the leaves obtained after selection in the inbred generation (S3) of winter rye (Secale cereale L.) were the object of the present studies. The feature of a white yellow irregular pattern in all lines was monomeric and recessive. This trait in L158b, wch, and zp was determined by the same recessive gene marked with the symbol wyv1, "white yellow virescent." The gene responsible for the appearance of the above feature in line L24 was nonallelic to the gene wyv1, therefore it was designated as the sequent gene of the same series--wyv2. The studied forms of plants were characterized by a diminution in the number of plastids and in chlorophyll (a plus b) content in mesophyll cells of leaves. Contrary to typical ultrastructure of chloroplasts in dark green plants (control), plastids in lines with the white yellow virescent pattern on the leaves showed variations in ultrastructure from numerous granal and intergranal thylakoids to a reduced number.
