The potato (Solanum tuberosum L.), one of the most important food crops worldwide, is sensitive to environmental stresses. Sensor–responder complexes comprising calcineurin B-like (CBL) proteins and CBL-interacting protein kinases (CIPKs) not only modulate plant growth and development but also mediate numerous stress responses. Here, using a Hidden Markov Model and BLAST searches, 27 CIPK genes were identified in potato and divided into five groups by phylogenetic analysis and into two clades (intron-poor and intron-rich) by gene structure analysis. Quantitative reverse-transcription PCR (qRT-PCR) assays revealed that StCIPK genes play important roles in plant growth, development and abiotic stress tolerance. Up-regulated expression of StCIPK10 was significantly induced by drought, PEG6000 and ABA. StCIPK10 enhances both the ability of potato to scavenge reactive oxygen species and the content of corresponding osmoregulation substances, thereby strengthening tolerance to drought and osmotic stress. StCIPK10 is located at the intersection between the abscisic acid and abiotic stress signaling pathways, which control both root growth and stomatal closure in potato. In addition, StCIPK10 interacts with StCBL1, StCBL4, StCBL6, StCBL7, StCBL8, StCBL11 and StCBL12, and is specifically recruited to the plasma membrane by StCBL11.

Potato (Solanum tuberosum L.)  is the most popular tuber crop in West Bengal, India. Seed tuber is the single most important factor in potato cultivation and if the seed is not of good quality, then optimum production could not be achieved. Unavailability of good quality seed, high price and untimely supply of seed at the village level are the main limiting factors in potato production. Field experiments were conducted during rabi season of 2017-18 and 2018-19 at Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal to determine the effects of intra row spacing, dates of haulm cutting and fertilizer dose on disease free quality seed grade tuber production of potato. The experiment was laid out in a split split plot design with three replications having twelve treatment combinations. The results revealed that with the decrease in intra row spacing from 20cm to 15cm seed grade size (< 75g) tuber yield and numbers and total tuber numbers were significantly increased but marketable grade (> 75 g) tuber yield and numbers were significantly reduced. Haulm cutting at 65 DAP increased the seed grade size tuber yield and numbers over 75 DAP. With the decrease in fertility levels from 100% RDF of NPK to 50% RDF of NPK the seed grade tuber production and number were significantly increased at 5% level of significance. Disease incidence and intensity of Phoma leaf spot decreased and early blight increased with decreasing doses of fertilizers. No viral disease was observed. Dehaulming at 65 DAP was found safer so far as infestation and chances of viral disease transmission by the sucking pests were concerned. From the present study it may be concluded that, for quality seed tuber production of potato and to get highest net return under New Alluvial Zone of West Bengal, use of 50cm X 15cm spacing along with haulm cutting at 65 DAP, when planting is done on first week of November and grown with 50% RDF of NPK was found best.
