Leguminosae, the third largest angiosperm family, is a taxon displaying the exceptional diversity of flowers and having great agricultural significance. Despite the broad range of reproductive strategies in this group, floral nectar is a key reward of legumes. The paper aims to summarize the available data on structure, ontogeny, regulation, and po...
The third largest angiosperm family, Leguminosae, displays a broad range of reproductive strategies and has an exceptional practical value. Whereas annual legume species are mostly planted as crops, there is a significant interest in breeding and cultivating perennials. It is therefore of importance to compare reproductive traits, their interaction...
Flowers of Leguminosae, the third largest angiosperm family, display outstanding diversity and are adapted to different modes of pollination. However, floral nectar is their most common and important reward. The morphology and position of the specialized floral nectaries (FNs) have been described only in the minority of legumes to date, so the inve...
Floral nectar is a key reward in Leguminosae despite the exceptional diversity of flowers in this family. The paper aims to summarize the available data on structure, ontogeny, regulation, and possible evolution of the leguminous floral nectaries.

Despite the rich diversity of floral morphology and pollination adaptations in Leguminosae, floral nectar is their most common and important reward. The exact origin of floral nectaries (FNs) in legumes has been a matter of debate for more than a century. It was hypothesized that FNs are either derivatives of stamens or have no homology with any fl...
The seed yield in pea (Pisum sativum L.) depends on numerous environmental and genotypic factors. The ongoing climate changes draw one's attention to genetics and variation of underexplored reproductive traits. This study focuses on ovule number (ON) and flower size expressed as a length of flag petal (FL), in terms of their heritability, variabili...
Angiosperm flowers are subject to spontaneous fluctuations in their structure, so in the same individual plant normal and anomalous flowers may coexist. While extra or missing organs usually do not affect the efficiency of pollination in poly-symmetric flowers, such meristic changes may impair the interaction between floral parts in monosymmetric f...
The vast majority of angiosperms attracts animal pollinators with the nectar secreted through specialized floral nectaries (FNs). Although there is evidence that principal patterns of regulation of FN development are conserved in large angiosperm clades, these structures are very diverse considering their morphology and position within a flower. Mo...
Various regulatory genes encoding transcription factors and miRNAs regulate carpel number. Multicarpelly is normally associated with increased size of the floral meristem, and several genetic factors have been discovered that influence this characteristic. A fundamental understanding of the regulatory genes affecting carpel number can facilitate st...

The largest angiosperm genus Astragalus exhibits a wide range of morphological variation regarding flowers, inflorescences and especially pods. As a result, some of its species are widely distributed, while others are local endemics and often threatened. It is of significant interest to trace features which provide a higher success for some species...
The third largest angiosperm family, Leguminosae, exhibits a relatively wide range of variation in morphology of gynoecium. Some of gynoecial patterns found in this taxon are of special interest, as they resemble ones previously described in the earliest angiosperms. The different orientations of carpels in legumes appear easily switchable through...
The amount of DNA per nucleus, usually expressed in terms of the amount within a haploid chromosome set (C-value), is known to have significant impacts on morphological and physiological features in plants. Among these features, C-value influences replication time and hence duration of the whole cell cycle, as well as sizes of cells. The Fabeae tri...

Background. Breeding new crops is associated with a risk of decrease (erosion) in genetic polymorphism. It is associated mainly with the fact that only a limited range of pre-existing cultivars and forms are used for breeding new cultivars. The Russian cultivars of garden pea (Pisum sativum L.) are characterized by a high level of phenotypic variab...
Androecium and corolla morphology is characterized in the Pterocarpus clade (Leguminosae: Papilionoideae: Dalbergieae) with a special aim to compare genera with monosymmetric (Arachis, Centrolobium, Pterocarpus, Tipuana) and polysymmetric (Etaballia, Inocarpus) flowers. The study on epidermal features of petals indicates that monosymmetry in Etabal...
This paper aims to briefly review how a garden pea (Pisum sativum L.) is imprinted in the folk culture of Russian-speaking territories. Having been the most important legume of this territory for millennia, this plant left its traces in local and personal names, proverbs and idioms. Some of these pieces of folklore may help to reconstruct the pheno...
A significant diversity of flower structure in angiosperms is defined by few parameters, among which one may list floral merism and symmetry as the most important. However, observation of normal variation in different taxa indicates that high floral merism (more than six organs) is very rarely associated with a monosymmetry. Precise mechanisms unde...
Until recently, chemical derivatives of platinum group metals have not been in a systematic direct contact with living organisms. The situation has changed dramatically due to anthropogenic activity, which has led to significant redistribution of these metals in the biosphere. Millions of modern cars are equipped with automotive catalytic converter...

As a result of recent phylogenetic researches, water chestnut (Trapa, former Trapaceae) was found nested in Lythraceae. This work aims to review the existing publications on floral morphology and ontogeny of Trapa and to revisit these topics with the scanning electron microscopy. Although previously described as tetramerous, flowers of Trapa are di...
Pea ( Pisum sativum ) is one of relatively few genetically amenable plant species with compound leaves. Pea leaves have a variety of specialized organs: leaflets, tendrils, pulvini and stipules, which enable the identification of mutations that transform or affect distinct parts of the leaf. Characterization of these mutations offers insights into...
One of the approaches in plant breeding is introduction of different morphological mutations in a genotype of cultivated forms. The resulting phenotypic polymorphism among crops often goes far beyond the existing range of variation observed in wild-growing plants. This is also vital for a legume family (Fabaceae), with many of its members being imp...
The vast majority of the species of family Leguminosae have an apocarpous monomerous gynoecium. However, only a few taxa regularly produce multicarpellate gynoecia. The only known species of papilionoid legumes which has both a typical “flag blossom” and more than one carpel is Thermopsis turcica (tribe Thermopsideae). We studied the floral ontogen...
Most representatives of the third largest angiosperm family, Leguminosae, share monosymmetric flowers with a precisely defined number and morphology of all parts especially the corolla. However, in some lineages monosymmetry is lost. This alteration is usually associated with an increase of variation in number of floral organs. This paper reports t...
This work is dedicated to the problem of natural variability of flowers with different types of symmetry. We focus on a comparative study of floral merism in Leguminosae with mono-and polysymmetric flowers. With few exceptions, most of the analyzed species exhibit a certain level of variation. Generally, monosymmetric flowers appear more stable tha...

Detailed phenotypic analysis of pea accession marked with mutation determinate habit (deh) was carried out in comparison with indeterminate forms. Mode of inheritance of mutation deh was studied. Mutation appeared semidominant, as first filial progeny from crosses deh × DEH had an intermediate phenotype.
Our paper provides new data on genetic control of flower number per axillary inflorescence in garden pea (Pisum sativum L.). This trait is of both agricultural and evolutionary interest. Analysis of crosses enabled us to conclude that, in addition to previously proposed models of monogenic recessive and cumulative polymery, two genes can control a...
A comparison of floral and inflorescence morphology was conducted between normal and fasciated accessions of Pisum sativum and Lupinus angustifolius. Pea plants with a fasciation of the main stem exhibited fewer flowers per axillary inflorescence and in some cases fewer ovules per carpel. Flowers of fasciated peas of different origin appeared norma...

На примере гороха посевного кратко рассмотрены основные перспективы, открывающиеся для селекции по мере развития факториальной концепции наследственности. Проанализированы возможные последствия использования в селекции культуры принципов, действующих в природных популяциях. Обсуждается роль маркер-опосредованного отбора в выведении новых сортов.
Since investigations of Gregor Mendel, a garden pea (Pisum sativum L.) remains the convenient model object for studies on genetic control of different aspects of plant development. The most intriguing are the ontogeny of compound inflorescence, monosymmetric flower, symbiotic nitrogen fixation and compound leaf. The latter aspect is still in a stag...
Most papilionoid legumes (Leguminosae) are characterized by zygomorphic flowers. Features of monosymmetry are inherent to all floral whorls. We compare flowers of two species of papilionoid legumes with anomalously radialized corollas. Except for vexilloid mode of all five petals, these flowers were remarkable with their free androecium and (in cas...
The antidepressant properties of newly synthesized analog of arginine-vasopressin fragment analog, Ac-D-SPRG, were tested using Porsolt’s swimming test on white rats. It was demonstrated that this substance when injected intranasally decreases the depression in comparison with the control group.

Mutations which cause determinate growth pattern in different leguminous species are briefly reviewed. Both their molecular basis and breeding value are in scope. With rare exceptions, the most part of cultivated legumes are characterized with an indeterminate growth pattern, when annual shoot proliferates unlimitedly producing new leaves and axill...
A variety of gynoecium types in the legume family is briefly reviewed in terms of phyllotaxis and spatial patterning. All variations can be narrowed down to changes in sizes of floral meristem and time of its proliferation. Increase in floral meristem size results in the initiation of more carpels, so the phyllotaxis of floral apex changes from alt...
Polymerous gynoecia are normally found in some members of Fabaceae, although the vast majority of this family is characterized by a gynoecium consisting of a single carpel. Summarizing the variation of gynoecium features in these species together with analysis of floral structure and ontogeny in mutants of pea (Pisum sativum L.) suggests to propose...
Wild perennial pea, Vavilovia formosa is a rare representative of the alpine flora. and its growing in ex situ conditions is very complicated. The assumption that the border between cataphylls and true leaves of perennial Fabeae coincides with the border between wintering and annual plant parts is confirmed by observations on V. formosa samples gro...

A study of fasciated pea Pisum sativum L. (Fabaceae) mutant Shtambovy in comparison with the wild type (Nemchinovsky cultivar) has shown that fasciation is a result of abnormal cohesion of axial or other structures which arise in a superfluous amount due to uncontrolled meristic processes. In some cases, the organs with the same number and position...
Questions
Question (1)
For comparative work on floral morphology, I'm looking for material of Etaballia dubia Benth. (Leguminosae). According to available descriptions, it inhabits the northern regions of South America. The best is to obtain both flowers and floral buds on different developmental stages fized in ethanol but there may be serious problems with transferring such "wet" material abroad, so even dry herbarized flowers sent via a common post may be very valuable and helpful.
Many thanks in advance for any information.
UPDATE: Thanks for attention, it is not relevant any more.
