Cold stress alters transcription in meiotic anthers of cold tolerant chickpea (Cicer arietinum L.)

Abstract: BackgroundCold stress at reproductive phase in susceptible chickpea (Cicer arietinum L.) leads to pollen sterility induced flower abortion. The tolerant genotypes, on the other hand, produce viable pollen and set seed under cold stress. Genomic information on pollen development in cold-tolerant chickpea under cold stress is currently unavailable.ResultsDDRT-PCR analysis was carried out to identify anther genes involved in cold tolerance in chickpea genotype ICC16349 (cold-tolerant). A total of 9205 EST bands w… Show more

“…Since, male organ development is a complex phenomenon involving premeiotic and postmeiotic events and anther dehiscence (Zhang & Wilson, ; Wilson & Zhang, ; present study), and cold affects chickpea anther growth in an age dependent manner (present study); precise descriptions of floral/anther development will allow exactitude in understanding the effects of LT in chickpea. Such descriptions, if available earlier, Singh et al () and Sharma and Nayyar () might have focussed on specific stage(s) and reported genes involved in floral development or LT‐tolerance at specific anther development events such as meiosis, tetrad formation, etc. In addition to it, the study also has implications in identifying key players involved in abiotic stress tolerance.…”

“…LT in chickpea also induces pollen sterility, pollen tube distortion, ovule abortion, and reduces fruit set (Kumar et al, ; Srinivasan, Saxena, & Johansen, ; Thakur, Kumar, Malik, Berger, & Nayyar, ). Induction of pollen sterility under LT is considered to be the major reason for flower abortion in chickpea (Kumar et al, ); however, mechanisms underlying LT‐induced pollen sterility or the impact of LT at different stages of anther/pollen development and on microsporogenesis, microgametogenesis, and tapetum degeneration remained largely unexplored with the exception of reports on pollen structure deformities and hypertrophy of tapatum under LT (Kumar et al, ) It appears that anthers of tolerant chickpea under LT produce viable pollen by upregulating triacylglycerol and carbohydrate metabolism and by regulating specific set of genes that are involved in pollen development (Sharma & Nayyar, ). In other crops, LT disrupts carbohydrate pool in anthers of susceptible plants as a result of abscisic acid‐induced downregulation of tapetum cell wall bound invertases and monosaccharide transporter genes, thereby resulting in pollen sterility (Oliver et al, ; Oliver, Dennis, & Dolferus, ; Sharma & Nayyar, ).…”

“…These crops are unable to survive in cold temperatures and the development of cold-resistant cultivars has been suggested (Thakur et al, 2010). During the reproductive stage, cold stress reduces yields by affecting flower organs, inducing pollen sterility, pollen tube distortion, ovule abortion, or flower abscission, and thereby preventing the fruit from developing (Thakur et al, 2010;Sharma and Nayyar, 2014). Cold stress interrupts normal plant growth at the physiological, morphological, cellular, and genetic levels (Thakur et al, 2010;Wu et al, 2014).…”

“…This gene is involved in tapetal development, programmed cell death (PCD) and pollen grain sterility (Zhang et al, 2014). Many other genes such as 2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase superfamily protein (Leisner et al, 2014), cysteine/histidine-rich C1 domain family protein (Zhang et al, 2014), heat shock protein 18.2 (Kim and Hong, 2001), zinc finger (C3HC4-type RING finger) family protein (Wu et al, 2014), cellulose synthase like A14 (Park et al, 2013), homeodomain-like superfamily protein (Wilson et al, 2011), syntaxin of plants 71 (Sharma and Nayyar, 2014), cellulose synthase 5 (Park et al, 2013), plant selfincompatibility protein S1 family (Samuel et al, 2009), cytochrome P450 (Zhao et al, 2015), ubiquitin family protein (Mazzucotelli et al, 2006), malectin/receptor-like protein kinase family protein (Matschi et al, 2013), glutamine synthetase 1;4 (Bargaz et al, 2015), auxin response factor 19 (Li et al, 2016), AGAMOUS-like 24 (Yu et al, 2002), P450 reductase 1 (Bak et al, 2011) were also identified associated with the cytoplasmic male sterility, pollen tube and pollen coat development, boron deficiency, and seed pod development.…”
