“…In recent years, there has been a concern about the increase of early blight in potato fields, even in areas where the disease barely caused problems. The climatic tendency of increases in the temperature has shown changes in the behavior of Alternaria, with a higher severity of early potato blight [17,30]. The fact was manifested in this study, in the region of A Limia, with a notable increase in total Alternaria spores in the last two years.…”

Interrupted Wet Period (IWP) to Forecast the Aerial Alternaria in Potato Crops of A Limia (Spain)

Potato early blight caused by Alternaria solani generates significant economic losses in crops worldwide. Forecasting the risk of infection on crops is indispensable for the management of the fungal disease, ensuring maximum economic benefit but with minimal environmental impact. This work aimed to calculate the interrupted wet periods (IWP) according to the climate conditions of A Limia (Northwest of Spain) to optimize the prediction against early blight in potatoes. The study was performed during nine crop cycles. The relative hourly humidity and Alternaria concentration in the crop environment were taken into account. Alternaria levels were monitored by aerobiological techniques using a LANZONI VPPS-2000 volumetric trap. The relationships between weather conditions and airborne Alternaria concentration were statistically analyzed using Spearman correlations. To establish the effectiveness of wetness periods, the first important Alternaria peak was taken into account in each crop cycle (with a concentration greater than 70 spores/m 3 ). Considering the six interrupted wet periods of the system, it was possible to predict the first peak of Alternaria several days in advance (between 6 and 38 days), except in 2007 and 2018. Automated systems to predict the initiation of early blight in potato crop, such as interrupted wet periods, could be an effective basis for developing decision support systems. The incorporation of aerobiological data for the calculation of interrupted wet periods improved the results of this system.

“…The earliness of tuberisation dictates the time to crop maturity and is therefore a crucial factor in potato agronomy. Varieties that reach maturity quickly are particularly beneficial when potato is used as an intercrop or in environments where growing seasons are short due to climatic conditions and disease pressure (Adavi et al ., 2018).…”

TERMINAL FLOWER‐1/CENTRORADIALIS inhibits tuberisation via protein interaction with the tuberigen activation complex

et al. 2020

SUMMARY Potato tuber formation is a secondary developmental programme by which cells in the subapical stolon region divide and radially expand to further differentiate into starch‐accumulating parenchyma. Although some details of the molecular pathway that signals tuberisation are known, important gaps in our knowledge persist. Here, the role of a member of the TERMINAL FLOWER 1/CENTRORADIALIS gene family (termed StCEN) in the negative control of tuberisation is demonstrated for what is thought to be the first time. It is shown that reduced expression of StCEN accelerates tuber formation whereas transgenic lines overexpressing this gene display delayed tuberisation and reduced tuber yield. Protein–protein interaction studies (yeast two‐hybrid and bimolecular fluorescence complementation) demonstrate that StCEN binds components of the recently described tuberigen activation complex. Using transient transactivation assays, we show that the StSP6A tuberisation signal is an activation target of the tuberigen activation complex, and that co‐expression of StCEN blocks activation of the StSP6A gene by StFD‐Like‐1. Transcriptomic analysis of transgenic lines misexpressing StCEN identifies early transcriptional events in tuber formation. These results demonstrate that StCEN suppresses tuberisation by directly antagonising the function of StSP6A in stolons, identifying StCEN as a breeding marker to improve tuber initiation and yield through the selection of genotypes with reduced StCEN expression.

“…The probabilistic discussion using a large number of meteorological data allowed us to examine more useful climate change adaptation in agriculture. Previous studies, such as Hijmans (2003) and Adavi et al (2018), have only been deterministic, discussing how yields will be reduced by global warming, or how they will be able to reduce the yield loss with adaptation. These deterministic discussions could not discuss the possibility of future climate extremes that almost seldom occur in the current climate.…”

“…Tito et al (2018) revealed that the increase in pests and diseases of potato due to global warming also reduce yields. Adavi et al (2018) revealed that potatoes were exposed to high temperatures during the tuber grow period, which would increase the risk of yield loss. Other studies also suggested the risk of potato yield loss in sub-Saharan Africa (Pironon et al 2019), India (Pradal et al 2019, northern China (Zhao et al 2016;Wang et al 2019), and northern Europe (Pulatov et al 2015).…”

“…These kinds of data samples can be now obtained from a large number of ensemble simulations at various levels of warming. However, no studies used a large number of ensemble data to assess the risk of potato yield to global warming, although some used the global climate model simulation with tens of years length (Hijmans 2003;Stöckle et al 2010;Adavi et al 2018).
