Drought is one of the major abiotic factors affecting growth and productivity of plants by imposing certain morphological, physiological and biochemical changes at different growth stages. The objective of this work is to study key morphological, physiological and biochemical response of faba bean (Vicia faba L. var. 'minor') to soil water deficit stress and to assess the contribution of genetic factors in improving faba bean tolerance to water deficit. Plant of 11 faba bean cultivars were grown in the greenhouse and subjected to three levels of water deficit (90, 50 and 30% of field capacity (FC)) in a simple randomized design for 20 days. Water deficit effects on plant growth, relative water content (RWC), gaz exchange, chlorophyll a (Chla) and Chlorophyll b (Chlb) content, osmoprotectant accumulations (such as proline and soluble sugars), antioxydant enzyme activities and grain yield were determined. Soil water deficit stress reduced growth and affected physiological parameters, especially antioxidant enzyme activities. Water deficit also increased proline, soluble sugars and protein contents. The studied cultivars significantly differed in their responses to water deficit stress. Photosynthetic parameters were less affected in the 'Hara' cultivar. Furthermore, this cultivar produced the highest value of grain yield at 30% FC, and showed higher antioxidant enzyme activities (CAT, GPX and APX), osmoprotectant accumulations, Chlb and RWC. The 'Hara' cultivar was found to be more tolerant to water deficit stress than the other cultivars. Our methodology can be used for assessing the response of faba bean genetic resources to soil water deficit. The identified tolerant cultivar can be utilized as a source for water stress tolerance in faba bean breeding programs aimed at improving drought tolerance. [less ▲]

Humic substances (HS) are complex and heterogeneous compounds of humified organic matter resulting from the chemical and microbiological decomposition of organic residues. HS have a positive effect on plant growth and development by improving soil structure and fertility. They have long been recognized as plant growth-promoting substances, particularly with regard to influencing nutrient uptake, root growth and architecture. The biochemical and molecular mechanisms through which HS influence plant physiology are not well understood. This study evaluated the bioactivity of landfill leachate and leonardite HS on alder (Alnus glutinosa L. Gaertn) and birch (Betula pendula Roth) during root elongation in vitro. Changes in root development were studied in relation to auxin, carbon and nitrogen metabolisms, as well as to the stress adaptive response. The cDNA fragments of putative genes encoding two ATP-binding cassette (ABC) transporters (ABCB1 and ABCB19) belonging to the B subfamily of plant ABC auxin transporters were cloned and sequenced. Molecular data indicate that HS and their humic acid (HA) fractions induce root growth by influencing polar auxin transport (PAT), as illustrated by the modulation of the ABCB transporter transcript levels (ABCB1 and ABCB19). There were also changes in alcohol dehydrogenase (ADH) and glutamine synthetase (GS) gene transcript levels in response to HS exposure. These findings confirmed that humic matter affects plant growth and development through various metabolic pathways, including hormonal, carbon and nitrogen metabolisms and stress response or signalization.

The aim of this study was to describe the embryos abortion process and the inheritance of the embryos abortion trait in Phaseolus vulgaris plants deficient in seed development. These plants were isolated within the second generation of an ethyl methanesulfonate (EMS) TILLING population of P. vulgaris cv. 'BAT93'. Mutant embryos show abnormalities mainly in suspensors, shoot apical meristem (SAM) and cotylédons from the globular to the cotyledon stages and abort before maturity compared to those observed in wild-types samples. Mutant embryos show also hyperhydricity and contain low amount of chlorophyll. Genetic analyses of F1, F2 and F3 populations from the crosses carried out between the mutagenized plants with aborting embryos and the wild-type plants indicated that the embryo abortion phenotype is maternally inherited and controlled by a single recessive gene. These Phaseolus mutant plants with aborting embryos constitute a valuable material for plant embryogenesis studies. [less ▲]

This review describes and discusses recent attempts to analyze the embryogenesis process in higher plants, through combination of descriptive, experimental, and genetic approach. Analysis of gene expression profiles has permitted to build hypothesis concerning the induced mechanisms in early phases of embryogenesis in higher plants. Such mechanisms involve specific transcriptional and post-transcriptional regulatory pathways as well as diverse signal transduction processes at each stage of plant development. [less ▲]
