The CGIAR crop improvement (CI) programs, unlike commercial CI programs, which are mainly geared to profit though meeting farmers' needs, are charged with meeting multiple objectives with target populations that include both farmers and the community at large. We compiled the opinions from more than thirty experts in the private and public sector on key strategies, methodologies and activities that could the help CGIAR meet the challenges of providing farmers with improved varieties while simult...

OST1/SnRK2.6 is a critical component connecting abscisic acid (ABA) receptor complexes and downstream components, including anion channels and transcription factors. Because OST1 is a serine/threonine kinase, several autophosphorylation sites have been identified. S175 is known to be critical for the kinase activity of OST1. We previously reported that BAK1 interacts with and phosphorylates OST1 to regulate ABA signaling. Here, we mapped additional phosphosites of OST1 generated by autophosphory...
A fundamental question in developmental biology is how the progeny of stem cells become differentiated tissues. The Arabidopsis root is a tractable model to address this question due to its simple organization and defined cell lineages. In particular, the zone of dividing cells at the root tip, the root apical meristem, presents an opportunity to map the gene regulatory networks underlying stem cell niche maintenance, tissue patterning, and cell identity acquisition. To identify molecular regula...
In order to tackle the cumulative adverse effects of global climate change, reduced farmland and heightened needs of an ever-increasing world population, modern agriculture is in urgent search of solutions that can ensure world food security and sustainable development. Classical crop breeding is still a powerful method to obtain crops with valued agronomical traits, but its potential is gradually compromised by the menacing decline of genetic variation. Resorting to the epigenome as source of v...

Heterosis occurs when the F1s outperform their parental lines for a trait. Reciprocal hybrids are obtained by changing the cross direction of parental genotypes. Both biological phenomena could affect the external and internal attributes of fleshy fruits. This work aimed to detect reciprocal effects and heterosis in tomato (Solanum lycopersicum) fruit quality traits and metabolite content. Twelve agronomic traits and 28 metabolites identified and estimated by 1H-NMR were evaluated in five cultiv...

Arabidopsis flower primordia give rise to organ primordia in stereotypical positions within four concentric whorls. Floral organ primordia in each whorl undergo distinct developmental programs to become one of four organ types (sepals, petals, stamens, and carpels). The Arabidopsis transcription factors AINTEGUMENTA (ANT) and AINTEGUMENTA-LIKE6 (AIL6) are required for correct positioning of floral organ initiation, contribute to the specification of floral organ identity, and regulate the growth...
The evolution of photosynthesis and its associated metabolic pathways has been crucial to the successful establishment of plants, but has also challenged plant cells in the form of reactive oxygen species (ROS) production. Intriguingly, multiple forms of ROS are generated in virtually every plant cell compartment through diverse pathways. As a result, a sophisticated network of ROS detoxification and signaling that is simultaneously tailored to individual organelles and safeguards the entire cel...
Meiosis is a key feature of sexual reproduction. During meiosis homologous chromosomes replicate, recombine and randomly segregate, followed by the segregation of sister chromatids to produce haploid cells. The unique genotypes of recombinant gametes are an essential substrate for the selection of superior genotypes in natural populations and plant breeding. In this review we summarize knowledge on meiosis in diverse monocot and dicot crop species and provide a thorough resource of cloned meioti...

Indolamines are tryptophan-derived specialized metabolites that belong to the huge and ubiquitous indole alkaloids group. Serotonin and melatonin are the best-characterized members of this family, given their many hormonal and physiological roles in animals. Following their discovery in several plant families, the study of plant indolamines has flourished over the last few decades and their involvement in many important processes has been proposed, including stress responses, growth and developm...
Population growth has been closely associated with agricultural production, since the first famine predicted by Malthus (1798) up to the Green Revolution of the past century. Today, we continue to face increasing demand for food and crop production (Tilman et al., 2011). Considering the combined caloric or protein content of the 275 major crops used directly as human foods or as livestock and fish feeds, Tilman et al. (2011) forecast a 100% increase in global demand for crops from 2005 to 2050. ...
