“…It has been well established that a specific calcium (Ca 2+ ) signature is generated in response to a particular environmental stimulus (Trewavas and Malhó, 1998;Scrase-Field and Knight, 2003;Luan, 2009;Kudla et al, 2010). The Ca 2+ changes are primarily perceived by several Ca 2+ sensors such as calmodulin (Reddy, 2001;Luan et al, 2002), Ca 2+ -dependent protein kinases (Harper and Harmon, 2005), calcineurin B-like proteins (CBLs; Luan et al, 2002;Batisti c and Kudla, 2004;Pandey, 2008;Luan, 2009;Sanyal et al, 2015), and other Ca 2+ -binding proteins (Reddy, 2001;Shao et al, 2008) to initiate various cellular responses.…”

“…In several plant species, multiple members have been identified in the CBL and CIPK family (Luan et al, 2002;Kolukisaoglu et al, 2004;Pandey, 2008;Batisti c and Kudla, 2009;Weinl and Kudla, 2009;Pandey et al, 2014). Involvement of specific CBL-CIPK pair to decode a particular type of signal entails the alternative and selective complex formation leading to stimulus-response coupling (D'Angelo et al, 2006;Batisti c et al, 2010).…”

The role of calcium-mediated signaling has been extensively studied in plant responses to abiotic stress signals. Calcineurin Blike proteins (CBLs) and CBL-interacting protein kinases (CIPKs) constitute a complex signaling network acting in diverse plant stress responses. Osmotic stress imposed by soil salinity and drought is a major abiotic stress that impedes plant growth and development and involves calcium-signaling processes. In this study, we report the functional analysis of CIPK21, an Arabidopsis (Arabidopsis thaliana) CBL-interacting protein kinase, ubiquitously expressed in plant tissues and up-regulated under multiple abiotic stress conditions. The growth of a loss-of-function mutant of CIPK21, cipk21, was hypersensitive to high salt and osmotic stress conditions. The calcium sensors CBL2 and CBL3 were found to physically interact with CIPK21 and target this kinase to the tonoplast. Moreover, preferential localization of CIPK21 to the tonoplast was detected under salt stress condition when coexpressed with CBL2 or CBL3. These findings suggest that CIPK21 mediates responses to salt stress condition in Arabidopsis, at least in part, by regulating ion and water homeostasis across the vacuolar membranes.

“…Boron is involved in complexes which are components of the cell wall (e.g., mannitol and polymannuronic acid), influences enzyme activity (e.g., polyphenol oxidase and peroxidase) and is also involved in cell division and elongation (DORDAS; BROWN, 2005;MATOH;KOBAYASHI, 1998;TANAKA;FUJIWARA, 2008). Calcium interferes with the integrity of the cell wall, especially in meristematic growth regions, and it is considered one of the most important signaling agents in metabolic pathways (DAYOD et al, 2010;MATOH;KOBAYASHI, 1998;PANDEY, 2008).…”

ABSTRACT.The in vitro organogenesis of woody species plays an essential role in the improvement of forest products by providing saplings with high commercial value. Furthermore, mineral nutrition plays an important role in the induction of organogenic responses. The objective of this study was to evaluate the effects of boron and calcium in the organogenesis of nodal segments from seedlings of Eucalyptus grandis growing under in vitro conditions. The concentration of boron and calcium in MS medium was modified to induce organogenic responses in 45-day-old nodal segments used as explants. After 60 days, the fresh weight, dry weight, ratio of fresh and dry weight, relative water content and relative matter content accumulated by the explants were evaluated. The concentrations of boron and calcium in the culture medium influenced the in vitro organogenic control of Eucalyptus grandis. Reduced combinations of boron and calcium induced callus formation and dry matter accumulation in the explants. A boron concentration of 100% (1.10 mg L ) of calcium allowed the induction of well-developed buds, which can be used for the regeneration of micro-plants.Keywords: bud induction, callogenesis, tissue culture, mineral nutrition. Efeitos do boro e cálcio na organogênese in vitro de Eucalyptus grandis RESUMO.A organogênese in vitro de espécies lenhosas caracteriza-se como fator fundamental para a obtenção de mudas com interesse comercial, gerando aplicações práticas na área do melhoramento florestal. Adicionalmente, a nutrição mineral desempenha papel importante nas respostas de indução organogênica. Objetivou-se avaliar o efeito do boro e cálcio na organogênese de segmentos nodais oriundos de plântulas de Eucalyptus grandis germinadas in vitro. Segmentos nodais com 45 dias após a germinação foram utilizados como explantes. Os explantes foram submetidos a combinações de boro e cálcio em meio de cultura MS, visando induzir diferentes respostas organogênicas. Ao final de 60 dias de cultivo in vitro foram avaliados a matéria fresca, a matéria seca, relação entre matéria fresca e matéria seca, conteúdo relativo de água e conteúdo relativo de matéria acumulada pelos explantes. As concentrações de boro e cálcio no meio de cultura influenciaram o controle organogênico in vitro de Eucalyptus grandis. Combinações reduzidas de boro e cálcio induziram a formação de calo e acúmulo de matéria nos explantes.

“…In order to achieve specific physiological responses they activate a complex network analysis which consists of perception, transmission and processing of a specific signal. One of the early stages of the signal transduction pathway is the appearance of a large number of second messengers such as calcium ions and cyclic nucleotides (Pandey 2008).…”

Two calcium dependent protein kinases are differently regulated by light and have different activity patterns during seedling growth in Pharbitis nil

In this study using biochemical approaches we identified two calcium-dependent protein kinases (CDPKs) named PnCDPK52 and PnCDPK56 in soluble protein extracts from seedlings of Pharbitis nil. Both enzymes phosphorylated the specific substrate histone III-S in the presence of Ca 2? and cross-reacted with antibodies against the CDPK. PnCDPKs exhibited quite different activity and protein levels during germination and successive stages of seedling growth. PnCDPK52 protein level was high in seeds and during germination, whereas PnCDPK56 increased in the next stages of seedling growth, being the dominant enzymes in mature seedlings, of the light-and dark-grown plant. In all cases both activity and accumulation of protein PnCDPK56 was higher in dark grown plants whereas exposure to light reduced both factors. When etiolated cotyledons were exposed to light, the activity of PnCDPK56 was reduced to the basal level within 5 h. Conversely, increasing activity of PnCDPK56 in cotyledons of green plants shifted to darkness was extremely rapid, reaching the maximum level after just 1 h of darkness and then gradually decreased. Further lengthening of the darkness to 16 h resulted in a strong increase in activity at 12 h. These data indicate that at least two isoforms of CDPK are involved in germination and seedling growth of P. nil. The differences in PnCDPKs strongly argue for the pleiotropic role of these isoforms. It seems that PnCDPK52 is associated with the germination process and PnCDPK56 with seedling growth. Moreover it suggests that activity of PnCDPK56 is controlled by light via the photoreceptor-dependent pathway.
