“…To identify conserved and differential regulatory mechanisms in hot pepper and tomato, we investigated orthologous regulatory genes previously identified in tomato ripening. Expression of transcription factor genes (RIN 43 , TAGL1 (ref. 44) and NOR 45 ) and genes involved in ethylene signaling pathways (NR 46 , ETR4 (ref.…”

“…While redundant in Arabidopsis, SEP homologs have adopted different functions in other plants. A case in point is a tomato SEP homolog that is involved in fruit ripening but not in floral organ identity 49 . The SEP gene family has experienced further expansion in the monocotyledons.…”

Gene duplications, robustness and evolutionary innovations Gene duplications, robustness and evolutionary innovations AbstractMutational robustness facilitates evolutionary innovations. Gene duplications are unique kinds of mutations, in that they generally increase such robustness. The frequent association of gene duplications in regulatory networks with evolutionary innovation is thus a special case of a general mechanism linking innovation to robustness. The potential power of this mechanism to promote evolutionary innovations on large time scales is illustrated here with several examples. These include the role of gene duplications in the vertebrate radiation, flowering plant evolution and heart development, which encompass some of the most striking innovations in the evolution of life. Gene duplications, robustness, and evolutionary innovationsAndreas Wagner AbstractMutational robustness facilitates evolutionary innovations in biological systems. Gene duplications are unique kinds of mutations, in that they generally increase such robustness. The frequent association of gene duplications in regulatory networks with evolutionary innovation thus exemplifies a general mechanism linking innovation to robustness. I illustrate the potential power of this mechanism on large time scales with the role of gene duplications in the vertebrate radiation, flowering plant evolution, and heart development, which encompass some of the most striking innovations in the evolution of life. Mutational robustnessMutational robustness is a biological's system ability to withstand mutations. Such robustness exists on multiple levels of biological organization. A case in point are random mutagenesis experiments of various proteins. They suggest that only a small fraction of mutations affect protein function adversely. For instance, a study of the bacteriophage T4 lysozyme generated more than 2000 random amino acid changes in the protein. Only 16% of them affected lysozyme function 1 . Other examples come from regulatory gene networks, such as the molecular network specifying fruit fly segments. Such networks may tolerate much quantitative variation in interactions among network genes 2-5 . Examples at the highest level of organization include macroscopic traits. Even substantial genetic variation -ultimately caused by mutations -may leave such traits unchanged. Take the vulva of the nematode worms Caenorhabditis elegans and Pristionchus pacificus 6 . These organisms shared a common ancestor 200-300 million years ago. Their vulvae are very similar, yet the genetic and cellular networks producing them have diverged greatly. For example, whereas in C. elegans one specific cell -the anchor cell -induces vulva development, multiple gonadal cells are responsible for this induction in P. pacificus 7 . Similarly, the same key signaling molecules, such as Wnt, may play a positive role in the network for vulval induction in C. elegans, but a negative role in P. pacificus 8,9 . In sum, mutational robustness is everywhere, from proteins to or...

“…Além disso, é considerada uma espécie modelo para pesquisas básicas em genética e fisiologia vegetal, dada a disponibilidade de mutantes afetando importantes moléculas regulatórias como hormônios (ZSÖGÖN et al, 2008;CAMPOS et al, 2009;GRATÃO et al, 2009;LIMA et al, 2009) e fatores de transcrição do tipo MADbox (MAO et al, 2000;VREBALOV et al, 2002) e homeobox (CHEN et al, 1997;KIMURA et al, 2008 (VREBALOV et al, 2002), usada para produzir tomates com longa duração após a colheita, ou as mutações jointless (MAO et al, 2000) e ovate (LIU et al, 2002), que facilitam a colheita mecanizada. A mutação jointless faz com que os frutos maduros fiquem fortemente retidos no pedicelo, evitando que os tomates caiam das plantas por conta do choque mecânico, causado pela máquina colhedora.…”
