—We analyzed 621 lizard fecal pellets to assess the diet of the endemic lizard Gallotia galloti (Lacertidae) throughout one year in the thermophilous scrubland, the most threatened habitat in the Canary Islands. Indicating the importance of frugivory, 98.1% of pellets contained seeds from fleshy-fruited plant species (8,028 seeds in total), and the fruit volume reached 47.5%. The Canarian endem...

Key innovations may increase the number of taxa in a clade that possesses the proposed innovation in comparison to its sister group that lacks the trait through either increased speciation or reduced extinction rates. Comparing sister clades across several independent lineages provides statistical support that the trait has increased species diversity. Previous studies have indicated that there...

At Krymsk Experiment Breeding Station of VIR, as a result collecting, studying, and selective use myrobalan plum genetic diversity, the intraspecific taxonomy species Prunus cerasifera Ehrh. was clarified. Donors traits significant for breeding were identified and, with their use, adaptable cultivars plum, Russian clonal rootstocks stone fruit plants developed. Intraspecific classification P. i...

LTHOUGH self-compatible (SC) species frequently can hybridize as females A with related self-incompatible (SI) species, the reciprocal cross is often impeded by inhibition of pollen tube growth in the style. This unilateral incompatibility can also be demonstrated between species of widely separated genera, or even of different families, which suggests that it is of fundamental significance in ...

BACKGROUND AND AIMS Plants have evolved a variety of seed dispersal mechanisms to overcome lack of mobility. Many species embed seeds in fleshy pulp to elicit endozoochory, i.e. disseminating seed through the animal gut. In contrast to well-studied fleshy fruited plants, dry-fruited plants may exploit this dispersal mutualism by producing fleshy appendages as a nutritional reward to entice anim...

Pepper (Capsicum annuum L.) is one of the most widely grown vegetable crops in China, with widespread cultivation worldwide. Fruit weight (size) a complex trait controlled by multiple factors and an essential determinant pepper yield. In this study, we analyzed transcriptome two recombinant lines different fruit weights, ‘B302’ ‘B400’, at five developmental stages to reveal some differentially ...

In 1930 I described briefly a case of hybridity in which apparently there had been a union between an egg cell of Fragaria vesca L. (n = 7) from Hawaii and a single genom (n=7) of Fragaria virginiana Duchesne (n=28) from the eastern part of the United States. The variety of F . vesca used as the female parent had white fruit. This plant was isolated in a room containing no other plants and was ...
