Segregation in populations derived by crossing Sc. 260180, a yellow foliaged plant of Russian wild ryegrass (Elymus junceus Fisch.) and Sc. 25311, a normal green plant, showed the yellow foliage character carried by this population to be monogenic and recessive. The gene symbol y1 has been proposed for this character.

Segregation in populations derived by crossing heterozygous plants of Russian wild ryegrass (Elymus junceus Fisch.) (breeding line Sc. 25317) showed that the temperature-sensitive yellow foliage character carried by this population is monogenic and recessive. The temperature-sensitive plants were yellow when grown at about 10 C, but a normal green color when grown at higher temperatures. The gene symbol ty1 has been proposed for this character.

In tobacco mutants which contain ⅛ to 1/30 of the normal chlorophyll content per leaf area the content of yellow pigments (carotenoids) is also diminished but less in proportion to the chlorophyll content. The pale yellow-green mutant grows and matures provided that light intensity and temperature make up for the chlorophyll deficiency. In most green plants and algae light saturation of photosynthesis is reached between 5000 and 12,000 ergs/sec·cm2. The mutants continue to give higher photosynthetic rates until the incident intensity reaches 50,000 ergs/sec·cm2. While often unable to compensate their respiration at intensities at which the normal green plant approaches saturation, the pale yellow-green leaves are able to provide the mutant plant with two to three times the absolute amount of carbon dioxide assimilation per hour and leaf area at 50,000 ergs/sec·cm2 and 20° to 25°C. These observations are valid for red light λ > 600 mµ. In blue light λ < 575 mµ (below saturation levels) the mutants separate into two classes, one in which absorption by some carotenoid enhances the photosynthetic rate and the other in which the absorbing pigments are inactive and therefore depress the rate strongly. The unusual kinetics of photosynthesis in these chlorophyll-deficient tobacco mutants is reflected in the structure of their chloroplasts which we found to be of a kind thus far not described for healthy, normally growing, higher plants.

Segregation in population derived by crossing heterozygous progeny of Sc.260181, a variegated plant of Russian wild ryegrass, and Sc.25311, a normal plant, showed a 12 normal green:3 variegated:1 albino ratio indicating inheritance according to the dominant epistasis pattern for two factors.

A New Species

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.
