Description

[ENG:]

The dataset contains results from experiments investigating the impact of arbuscular mycorrhizal fungi (Rhizophagus irregularis) on the responses of Lotus japonicus under full irrigation and during short-term (1 week) and long-term (3 weeks) drought. The data include morphological measurements such as shoot and root length, leaf number, and fresh and dry biomass, as well as root architecture parameters including total root length, volume, diameter, and number of tips. Physiological indicators such as leaf relative water content (RWC) and proline concentration are also included, along with chlorophyll fluorescence parameters such as Fv/Fm, Y, ETR, and NPQ. Additionally, the dataset provides information on the level of root colonization by AMF assessed using microscopy (gridline-intersect method) and quantified by qPCR. The dataset covers six experimental treatments: plants inoculated with mycorrhizal fungi and control plants supplemented with two phosphorus concentrations, under drought and full irrigation. Experiments were conducted in a phytotron at the Poznań University of Life Sciences, in the Biocentrum building at Dojazd 11, Poland. Methods included root scanning and image analysis (WinRHIZO), chlorophyll fluorescence measurements using an OS5p fluorometer, leaf water status assessment by the Weatherley method (1950), proline determination following Bates et al. (1973), and AMF colonization evaluation by microscopy and qPCR using species-specific gene markers.

Zbiór danych obejmuje wyniki eksperymentów dotyczących wpływu arbuskularnej mikoryzy (Rhizophagus irregularis) na reakcje Lotus japonicus w warunkach pełnego nawodnienia oraz podczas krótkotrwałej (1 tydzień) i długotrwałej (3 tygodnie) suszy. Dane zawierają pomiary morfologiczne, takie jak długość pędów i korzeni, liczba liści oraz biomasa świeża i sucha, a także parametry architektury korzeni, w tym całkowitą długość, objętość, średnicę i liczbę włośników. Uwzględniono również wskaźniki fizjologiczne, takie jak względna zawartość wody w liściach (RWC) i zawartość proliny, oraz parametry fluorescencji chlorofilu, w tym Fv/Fm, Y, ETR i NPQ. Dodatkowo zebrano dane dotyczące poziomu kolonizacji korzeni przez grzyby AMF ocenianego metodą mikroskopową (gridline-intersect) oraz ilościowo przy użyciu qPCR. Zbiór obejmuje sześć wariantów eksperymentalnych, w tym rośliny inokulowane grzybem mikoryzowym, oraz rośliny kontrolne, suplementowane dwoma stężeniami fosforu, w warunkach suszy i pełnego nawodnienia. Badania przeprowadzono w fitotronie na terenie Uniwersytetu Przyrodniczego w Poznaniu, w budynku Biocentrum przy ulicy Dojazd 11, Polska. Metody obejmowały skanowanie korzeni i analizę obrazu (WinRHIZO), pomiary fluorescencji chlorofilu za pomocą fluorometru OS5p, ocenę zawartości wody w liściach metodą Weatherley (1950), oznaczanie proliny metodą Bates i wsp. (1973) oraz ocenę kolonizacji AMF mikroskopowo i za pomocą qPCR z wykorzystaniem specyficznych markerów genowych.
