The effects of cholera toxin on the responses of cultured Sertoli cells were compared with those elicited by follicle-stimulating hormone (FSH), and N6O2'-dibutyryl-3',5'-cyclic AMP (bu2cAMP). Addition of FSH or cholera toxin increased cAMP levels. Subsequently there was greater rates of conversion of testosterone to 17beta-estradiol, formation of(More)
Plant and animal pathogenic fungus Cochliobolus lunatus cause great economic damages worldwide every year. C. lunatus displays an increased temperature dependent-virulence to a wide range of hosts. Nonetheless, this phenomenon is poorly understood due to lack of insights on the coordinated secretome weaponries produced by C. lunatus under heat-stress(More)
Since translational start codons also occur internally, more-complex features within mRNA must determine initiation. We compare the potential secondary structure of 123 prokaryotic mRNA start regions to that of regions coding for internal methionines. The latter display an unexpectedly-uniform, almost-periodic pattern of pairing potential. In contrast,(More)
Since the introduction of the new genus Sinocalamus in 1940 which is now dissociated into Bambusa and Dendrocalamus, molecular markers have long been unable to discern members of the Bambusa–Dendrocalamus complex. Rapid concerted evolution governed by high level of transition/transversion at the noncoding DNA regions has limited the ability of internal(More)
Aspergillus terreus is one of the most harmful filamentous fungal pathogen of humans, animals and plants. Recently, researchers have discovered that A. terreus can cause foliar blight disease in potato (Solanum tuberosum L.). We used light and scanning electron microscopy, and performed proteomics analysis in an attempt to dissect the invasion process of A.(More)
Consumption of bamboo species with high level of total cyanogenic content (TCC) in Asia by many ethnic groups is significantly associated with food poisoning and occasionally Konzo (a neurological disorder). Adequate characterization of edible bamboo species with low level of TCC and high nutritious attributes is required for consumer's safety as well as(More)
We undertook an investigation to advance understanding of the host-range dynamics and biocontrol implications of Cochliobolus lunatus in the past decade. Potato (Solanum tuberosum L) farms were routinely surveyed for brown-to-black leaf spot disease caused by C. lunatus. A biphasic gene data set was assembled and databases were mined for reported hosts of(More)
Cochliobolus lunatus abundantly produces four-celled conidia at high temperatures (>30 °C) and under suitable conditions; the fungus colonizes potato (Solanum tuberosum L.) cultivars by adopting different invasion strategies at the microscopic level. Long-lasting defence during infection requires an upsurge in proteome changes particularly(More)
The current literature describes recovery from virus-induced symptoms as a RNA silencing defense, but immunity-related genes, including the structurally specific resistance gene analogs (RGAs) that may play a key role in tolerance and recovery is not yet reported. In this study, the transcriptome data of tolerant cassava TME3 (which exhibits a recovery(More)
High demand for edible bamboo shoots of Bambusa tulda and Melocanna baccifera in many Asian ethnic groups has led to the need for developing intensive bamboo farming. To achieve this, in vitro regeneration of bamboo plantlets is needed due to the long and irregular bamboo flowering cycle and scarcity of bamboo seeds. An effective protocol for plantlets(More)
