Shade avoidance in Trifolium repens: costs and benefits of plasticity in petiole length and leaf size.
We tested whether the degree of shade-induced plasticity in petiole length and leaf area is related to the mean trait value expressed under high-light conditions, and to what extent trait values expressed under high-light and shaded conditions affect plant performance. Thirty-four Trifolium repens genotypes were used with a wide range of petiole lengths and leaf areas. Plants were subjected to ...
متن کاملEffects of cell number and cell size on petiole length variation in a stoloniferous herb.
In stoloniferous species, the length of petioles is of pivotal importance because it determines the position of leaf blades within the canopy. From a mechanistic perspective, two developmental processes, cell division and cell elongation, are responsible for the length of a given petiole. This study aimed at quantifying the relative contributions of cell division and cell elongation to genotypi...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
Dehydrins (group 2 LEA proteins) tend to accumulate late in embryogenesis and in response to stress leading to cell dehydration (e.g., drought, low temperature, and salinity). The expression pattern of group 2 LEA genes is frequently associated with higher tolerance of crop plants to abiotic stresses such as cold and drought. All dehydrins have at least one conserved, lysine-rich 15-amino acid ...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
The recently described complex nature of some dehydrin-coding sequences in Trifolium repens could explain the considerable variability among transcripts originating from a single gene.1 For some of the sequences the existence of natural antisense transcripts (NAT s), which could form sense-antisense (SAS) pairs, was predicted. The present study demonstrates that cis-natural antisense transcript...
متن کاملOppositional Alleles Causing Cross-Incompatibility in Trifolium Repens.
N SEVERAL species in which cross-incompatibility is determined by I multiple oppositional alleles, different types of tests have shown that these series of alleles are very extensive. The test yielding the most decisive results and involving the fewest crosses consists of making all possible reciprocal combinations (that is, diallel crosses) between plants which have one S factor in common. Thi...
