“…Only Crepis vesicaria, a biennial or shortlived perennial forb, was unresponsive to warming. Cumulative annual temperature sums predict flowering in many species (12), but perennial species with high storage allocation may require multiple growing seasons to respond to altered environmental conditions (13). The effects of elevated CO 2 differed between grasses and forbs (significant CO 2 ϫ functional group interaction, P Ͻ 0.0001).…”

Shifting plant phenology (i.e., timing of flowering and other developmental events) in recent decades establishes that species and ecosystems are already responding to global environmental change. Earlier flowering and an extended period of active plant growth across much of the northern hemisphere have been interpreted as responses to warming. However, several kinds of environmental change have the potential to influence the phenology of flowering and primary production. Here, we report shifts in phenology of flowering and canopy greenness (Normalized Difference Vegetation Index) in response to four experimentally simulated global changes: warming, elevated CO 2, nitrogen (N) deposition, and increased precipitation. Consistent with previous observations, warming accelerated both flowering and greening of the canopy, but phenological responses to the other global change treatments were diverse. Elevated CO 2 and N addition delayed flowering in grasses, but slightly accelerated flowering in forbs. The opposing responses of these two important functional groups decreased their phenological complementarity and potentially increased competition for limiting soil resources. At the ecosystem level, timing of canopy greenness mirrored the flowering phenology of the grasses, which dominate primary production in this system. Elevated CO 2 delayed greening, whereas N addition dampened the acceleration of greening caused by warming. Increased precipitation had no consistent impacts on phenology. This diversity of phenological changes, between plant functional groups and in response to multiple environmental changes, helps explain the diversity in large-scale observations and indicates that changing temperature is only one of several factors reshaping the seasonality of ecosystem processes.

“…Due to large amount of water in plant tissues, the behavior of cell water under different temperatures is a key factor for cell survival. Depending on species and developmental stages, plants can grow healthy in wide ranges of temperatures (Went 1953). Beyond these ranges, plants could suffer from severe temperature damages.…”

Plants have evolved with complex signaling circuits that operate under multiple conditions and govern numerous cellular functions. Stress signaling in plant cells is a sophisticated network composed of interacting proteins organized into tiered cascades where the function of a molecule is dependent on the interaction and the activation of another. In a linear scheme, the receptors of cell surface sense the stimuli and convey stress signals through specific pathways and downstream phosphorylation events controlled by mitogen-activated protein (MAP) kinases and second messengers, leading to appropriate adaptive responses. The specificity of the pathway is guided by scaffolding proteins and docking domains inside the interacting partners with distinctive structures and functions. The flexibility and the fine-tuned organization of the signaling molecules drive the activated MAP kinases into the appropriate location and connection to control and integrate the information flow. Here, we overview recent findings of the involvement of MAP kinases in major abiotic stresses (drought, cold and temperature fluctuations) and we shed light on the complexity and the specificity of MAP kinase signaling modules.

Resumo A cultura do crambe surge como alternativa de produção, destacando sua precocidade e o potencial para a produção de óleo, em estação fria. A escassez de informações sobre parâmetros climáticos e fenológicos conduziu à determinação da temperatura basal inferior, da duração do ciclo e da constante térmica da cultura do crambe em Frederico Westphalen (RS). O trabalho foi composto por sete épocas de semeadura em 2009 e quatro em 2010. A temperatura basal inferior foi determinada pelos métodos do menor desvio-padrão e do desenvolvimento relativo. A temperatura basal para o subperíodo emergência-maturação (EME-MAT) foi de 9,5 ºC, enquanto para os subperíodos emergência-início da floração (EME-IFLO), emergência-fim da floração (EME-FFLO) e início da floração-fim da floração (IFLO-FFLO) foram, respectivamente, de 10,2 ºC, 10,8 ºC e 10,0 ºC, obtidas pelo método do menor desvio-padrão. O subperíodo compreendido entre EME-MAT variou de 74 a 136 dias, com duração média de 96 dias. Para os subperíodos EME-IFLO, EME-FFLO e IFLO-FFLO a duração média foi, respectivamente, de 52, 82 e 29 dias. Considerando-se os valores de temperatura basal para cada subperíodo, a duração média entre EME-MAT foi de 691 ºC dia, variando entre 576 ºC dia e 792ºC dia. Para os subperíodos EME-IFLO, EME-FFLO e IFLO-FFLO, a duração média do foi de 279 ºC dia; 444 ºC dia e 220 ºC dia, respectivamente. Palavras-chave:Crambe abyssinica Hochst., temperatura, fenologia. Basal temperature, crop growth cycle duration and growing degree-days of crambe AbstractCrambe is an alternative crop, precocious and with potential to produce oil during the cold season. The scarcity of information about climatic and phenological parameters led to the determination of basal temperature, crop growth cycle duration and growing degree-days of Crambe. The research was composed of seven sowing dates in 2009 and four in 2010. Basal temperature was determined by the methods of least variability and relative development. The basal temperature for the subperiod emergence-maturation (EME-MAT) was 9.5 °C, whereas for the subperiods seedling emergency-early flowering stage (EME-IFLO), seedling emergency-end of flowering (EME-FFLO) and early flowering-end of flowering (IFLO-FFLO) were 10.2 ºC, 10.8 °C and 10.0 ºC, respectively. The subperiod between EME-MAT ranged from 74 to 136 days with an average duration of 96 days. For EME-FLO, EME-FFLO and IFLO-FFLO the average duration was 52, 82 and 29 days, respectively. Considering the values of basal temperature for each period or subperiod, the average time between EME-MAT was 691 ºC day, ranging between 576 ºC day and 792 ºC day. For EME-IFLO, EME-FFLO and IFLO-FFLO, the average was 279 ºC day, varying between 444 °C day and 220 ºC day.
