The B Genes and their Phenotypic Expression in Cucurbita: an Overview

Cucurbit Genetics Cooperative Report 19:73-77 (article 27) 1996 Oved Shifriss 21 Walter Avenue, Highland Park, NJ 08904 The B genes are nuclear mutants, and each B gene conditions precocious depletion of chlorophyll. In fruits, these genes can be expressed in all known genetic backgrounds. But in some backgrounds they can also be expressed in one […]

Control of Chlorophyll During Plant Development: Hypothesis

Cucurbit Genetics Cooperative Report 12:82-83 (article 34) 1989 Oved Shifriss 21 Walter Avenue, Highland Park, NJ 08904 The term “control” in the title pertains to a series of steps that transforms proplastids into chloroplasts, the organelles of chlorophyll synthesis. These steps occur in competent cells that are exposed to light. According to present hypothesis there […]

Relationship between Gene B and Gene Ses-B in Cucurbita pepo L.

Cucurbit Genetics Cooperative Report 12:79-81 (article 33) 1989 Oved Shifriss 21 Walter Avenue, Highland Park, NJ 08904 Gene B conditions precocious depletion of chlorophyll. And the loss of chlorophyll is often associated with precocious yellow pigmentation. The primary target of B is the fruit (2). But B can also affect other potentially photosynthetic organs, depending […]
