Aims and scope
Biologia plantarum, an international journal for experimental botany founded in 1959 by Professor Bohumil Nìmec publishes original scientific papers, brief communications, reviews and hypotheses in plant biology fields of plant physiology, plant development, plant biochemistry and biophysics, plant cell biology, large scale plant omics and systems biology, physiological anatomy, ecophysiology, genetics, molecular biology, phytopathology, plant evolution, structure-function relationship, functional traits in plants, and tree biology.

Ascorbic acid (AsA) and glutathione (GSH) contribute to defense responses under abiotic stresses. The present study explored the ascorbate-glutathione cycle and ascorbate regeneration under high concentration (30 mM) of cadmium in the tea plant (Camellia sinensis L.). The tea leaves showed speckles and necrosis from the third day of Cd treatment. The content of superoxide anion (O2.-) and hydrogen peroxide (H2O2) in the leaves were significantly higher until the seventh day after Cd treatment. The content of O2.- and H2O2...

Owing to cold resistance and a lack of heat resistance in spinach (Spinacea oleracea L.), heat is the primary constraint that limits its production in summer. This study examined the auxiliary effects of spinach rhizosphere microbes on improving the heat resistance of spinach. A strain isolated from the rhizosphere soil of heat-stressed spinach was identified as Bacillus subtilis and designated B. subtilis BE-L21. It produces indoleacetic acid, amylase, and protease and solubilizes phosphorus. Further research revealed that spinach seedlings inoculated with this strain of B. subtilis had increased content of soluble protein,...

Plants exhibit morphological plasticity in response to changes in the proportion of far-red radiation (FR). However, little is known about the response to a sudden increase of FR component. Cucumber seedlings were acclimatized to radiation without FR (FR-) for 1 - 5 d after germination, and then transferred to radiation containing FR (FR+) at levels similar to those in natural sunlight. Other seedlings were acclimatized to FR- or FR+, which was maintained continuously. The sudden increase in FR damaged the cotyledons and the first true leaf, especially when radiation was changed from FR- to FR+ at days 3 or 4 after germination. Necrosis of the damaged...

Preventing extinction is one of the greatest challenges facing the global community. Nursery stock breeding is an effective means to restore endangered species, such as Horsfieldia hainanensis Merr., with difficulty in natural regeneration period. In this study, we investigated the optimum combination of irradiance and nitrogen for the cultivation of H. hainanensis seedlings by comparing twenty treatments with different combinations of irradiances (100, 67.5, 45.7, 15.6 % of full natural irradiance) and five levels of N supply (0, 1.8, 3.6, 5.4, 7.2 g plant-1). We found that the growth and photosynthetic efficiency of seedlings...
Extracellular self-DNA induces local inhibition of growth, regulates production of reactive oxygen species, and gene expression in rice rootsOriginal Papers
T. O. S. TJIA, K. MEITHA, P. SEPTIANI, R. AWALUDIN, D. SUMARDI

The capacity of extracellular self-DNA (esDNA) to inhibit growth is getting more research attention as this could be explored for several purposes, including the development of specific bioherbicides. While the inhibitory effect has been studied in several dicotyledon species, little is known about the effects and subsequent signaling processes in monocots. Here, we measured the growth, counted the number of lateral and crown roots, determined greenness index, quantified the production of O2.- and H2O2, and determined the expressions of genes encoding antioxidant enzymes (SODs and CATs) in rice...
The influence of ABA on the photosynthesis of the rare and endangered Emmenopterys henryi under salt stressOriginal Papers

Emmenopterys henryi Oliv., a monotypic genus in family Rubiaceae with high scientific and application value, is currently endangered. Adaptability of E. henryi to environment is important for its cultivation, management, and application. In this paper, the effect of abscisic acid (ABA) on the photosynthesis of E. henryi under salt stress was discussed. Results showed that 0.3 % (m/v) NaCl led to reduction of net photosynthetic rate (PN), instantaneous carboxylation efficiency (ICE), and Rubisco activity but the increase of intercellular CO2 concentration (ci), which were remarkable relieved by ABA...
