A protein-linger strategy keeps the plant on-hold after rehydration of drought-stressed Beta vulgaris

ABSTRACT: A drought stress and recovery time course experiment was carried out under controlled environmental conditions. In order to find regulatory key mechanisms enabling plants to rapidly react to periodic stress events, beets were either subjected to 11 days of progressive drought, or were drought stressed for 9 days followed by gradual rewatering for 14 days. Based on physiological measurements of leaf water status and changes in morphology, plants experienced a switch from moderate to severe water stress between day 9 and 11 of drought.

Most crop plants are exposed to intermittent drought periods. To cope with these continuous changes, plants need strategies to prevent themselves from exhaustive adjustment maneuvers. Drought stress recovery has been shown to be an active process, possibly involved in a drought memory effect allowing plants to better cope with recurrent aridity. An integrated understanding of the molecular processes of enhanced drought tolerance is required to tailor key networks for improved crop protection. Du ...[more]

Project description:The experiment was carried out during two vegetation seasons from 25th of April to 10th of September. Two Polish potato cultivars, the drought-tolerant Gwiazda and drought-sensitive Oberon were used. Selected tubers with transverse diameters of 3 - 4 cm were pre-sprouted for 2 weeks before planting. Plants were grown in a vegetation hall in pots filled with a thin layer of gravel on the bottom and the universal vegetable soil substrate ‘Hollas’ (Agaris Polska Ltd., Poland) produced from peat with the addition of chalk at a pH range of 5.5-6.5. Additionally, in phase 20 of the BBCH-scale of plant development, MIS-3 (Intermag) fertilizer was applied. Water content (WC) in volumetric basis in soil pots was measured according Black (1965). Weather conditions during the years of study were monitored using a Weather Campbell Station (Campbell Scientific Inc.) located in close proximity, and a thermohygrograph placed between pots. Meteorological data of air temperature, the photosynthetically active radiation, and humidity were comparable in the years of study and favorable for potato development. Three weeks after the initiation of the tuberisation phase (56 DAP), plants were divided into 3 groups, each consisting of 6 plants. The first group of plants was subjected to soil drought (remained without irrigation, day/night temperature 22°C/18°C), the second one to high temperature (day/night temperature 38°C/25°C) and the third one was watered according to needs and at optimal temperature (control plants, day/night temperature 22°C/18°C). Stress application lasted 14 days and finished at 70 DAP. During this period, plants were placed in phytotron equipped with six Hortilux Schreder Lamps with Philips light bulbs of 1600 W each. Air humidity was in the range 65-70%. WC under 14 days of soil drought reached 30% (v/v), and remained 80% (v/v) in control and high temperature conditions. During the recovery period, after 14 days of stress treatment, WC reached control levels. Plant root material for proteomic research was collected on the 14th day of stress treatment (70 DAP).
