Maternal Control

The interrelationship of the maternal and genetic control for seed weight, rate of tiller production, length of fifth leaf, and total adult plant production in a 5 × 5 diallel cross of Lolium perenne L. were studied by estimation of the phenotypic, environmental, genetic, and maternal correlations. Genetic and maternal components of increased seed size lead to a reduction in tillering, leaf size and final production indicating that large seeds are not generally advantageous to growth and development. Environmental factors which promoted tillering also increased leaf length. Maternal control showed a similar pattern. However, genetic control indicated that the faster the tillering, the shorter the leaves, thus emphasizing the possible danger of considering only a single factor in selecting for increased yield. Phenotypic correlations indicate that total production was determined largely by tiller production with environmental factors influencing leaf length and tiller production. Neither genetic nor maternal control of tiller number or leaf size at the seedling stage greatly influenced final production, indicating that selection for either of these characters separately would not likely influence yield. The controls for maternal and additive genetic effects were found to be different. Maternal effects were strong and extended well beyond the influence of seed size effects.

Maternal Control

Seed size is the result of complex molecular networks controlling the development of the seed coat (of maternal origin) and the two fertilization products, the embryo and the endosperm. In this study we characterized the role of Arabidopsis thaliana MADS-domain transcription factor SEEDSTICK (STK) in seed size control. STK is known to regulate the differentiation of the seed coat as well as the structural and mechanical properties of cell walls in developing seeds. In particular, we further characterized stk mutant seeds. Genetic evidence (reciprocal crosses) of the inheritance of the small-seed phenotype, together with the provided analysis of cell division activity (flow cytometry), demonstrate that STK acts in the earlier phases of seed development as a maternal activator of growth. Moreover, we describe a molecular mechanism underlying this activity by reporting how STK positively regulates cell cycle progression via directly activating the expression of E2Fa, a key regulator of the cell cycle. Altogether, our results unveil a new genetic network active in the maternal control of seed size in Arabidopsis.
