Abstract

Lupin species provide essential nutrients and bioactive compounds. Within pulses, they have one of the highest contents of proteins and fibers and are among the poorest in carbohydrates. The Mediterranean region is an important cradle area of the origin and domestication of cultivated white lupin (Lupinus albus L.). In this work, we present the characterization of 19 white lupin landraces collected from several sites in southern Italy, characterized by different pedoclimatic conditions. The protein contents and electrophoretic patterns, total polyphenols, phytic acid, lipids and phosphorous content, and reducing and anti-tryptic activities have been determined for each landrace. The relationships of the compositional characteristics, the area of origin of landraces and between compositional characteristics and thermo-pluviometric trends that occurred in the genotype comparison field during the two-year period between 2019 and 2020 are compared and discussed. From a nutritional point of view, some of the analyzed landraces differ from the commercial reference. The panel of molecular analyses performed can help in building an identity card for the grain to rapidly identify those varieties with the desired characteristics. [ABSTRACT FROM AUTHOR]

Abstract

Recent experimental results suggest that human and nonhuman primates differ in how they process visual information to assemble component parts into global shapes. To assess whether some of the observed differences in perceptual grouping could be accounted for by the prevalence of different grouping factors in different species, we carried out 2 experiments designed to evaluate the relative use of proximity, similarity of shape, and orientation as grouping cues in humans (Homo sapiens) and capuchin monkeys (Cebus apella). Both species showed similarly high levels of accuracy using proximity as a cue. Moreover, for both species, grouping by orientation similarity produced a lower level of performance than grouping by proximity. Differences emerged with respect to the use of shape similarity as a cue. In humans, grouping by shape similarity also proved less effective than grouping by proximity but the same was not observed in capuchins. These results suggest that there may be subtle differences between humans and capuchin monkeys in the weighting assigned to different grouping cues that may affect the way in which they combine local features into global shapes.

22. STOMATAL CARPENTER 1 CONTROLS STOMATA DEVELOPMENT BY AFFECTING SPEECHLES ACTIVITY

Author

CASTORINA, GIULIA

Abstract

Stomata consist of two specialised epidermal cells termed guard cells (GCs) surrounding a pore, through which gas exchange can occur. In Arabidopsis thaliana, a dedicated cell lineage is initiated and undergoes a series of cell divisions to produce a stoma. A set of basic helix-loop-helix (bHLH) transcription factors regulates the differentiation events through the lineage. The initiation and proliferation of stomatal lineage cells is controlled by the transcription factor SPEECHLESS (SPCH), which drive the asymmetric division of meristemoid mother cell to originate a small triangular cell termed meristemoid. Which transcriptional events precede stomata lineage specification and are required for correct GC patterning, however, remain unclear. The DOF transcription factor STOMATAL CARPENTER 1 (SCAP1) has previously shown to be expressed in GC and involved in stomata function, by activating a set of GC?specific genes required for GC maturation and activity. We show that SCAP1 expression can also be observed in young leaf primordia, before any GC differentiation occurs. The study of transgenic plants carrying a proSCAP1:GUS-GFP transcriptional fusion coupled with quantitative PCR analyses indicate that SCAP1 expression is maximal in a stomatal lineage competence domain, coincident with SPCH expression. We found that SCAP1 modulates stomata development; independent scap1 loss-of- function mutants show a reduced number of GCs whilst SCAP1 over expression lines have an increased number of GCs in addition to altered GC distribution and spacing patterns. Confocal imaging of SPCH-GFP protein in a background carrying inducible SCAP1 shows that SCAP1 activation results in an increased number of nuclei expressing SPCH-GFP. Our results suggest an early role for SCAP1 in GC differentiation through SPCH protein stabilization. SCAP1 may thus link different aspects of GC biology including specification, maturation and function.
