Seed shape in the model legumes Lotus japonicus and Medicago truncatula is described. Based in previous work with Arabidopsis, the outline of the longitudinal sections of seeds is compared with a cardioid curve. L. japonicus seeds adjust well to an unmodified cardioid, whereas accurate adjustment in M. truncatula is obtained by the simple transformation of scaling the vertical axis by a factor ...

ALCAROIDES is a single-gene recessive mutation in Hordeum uulgare var. ‘Bonus having pleiotropic effects on plant development. A sac-like structure forms at the lemma awn base. and the leaves of calcaroides plants are occasionally twisted or curled, and acquires a brown mottled appearance after obtaining full maturity. In a previous publication (STEBBINS and PRICE 1971), evidence was presented ...

Question: Are seed mass and shape related to persistence in the soil seed bank among 54 species of the Israeli flora? Search method: Persistence was determined by soil seed bank investigations in which the fraction of non-germinated viable seeds was regarded as the persistent soil seed bank. When seedling emergence had ceased but before new seeds were shed, all soil from the upper 5 cm of 120 q...

The morphology of 11 species of the genus Vicia from Iran was studied using Scanning Electron Microscopy (SEM). The main pattern in seed coat sculpturing in the species was papillose, but the size and the number of side ribs in papillae and the density of papillae, were different in various species. Four morphological characters of seeds: relative hilum length and shape, relative position of th...

Seed development is important for agriculture productivity. We demonstrate that brassinosteroid (BR) plays crucial roles in determining the size, mass, and shape of Arabidopsis (Arabidopsis thaliana) seeds. The seeds of the BR-deficient mutant de-etiolated2 (det2) are smaller and less elongated than those of wild-type plants due to a decreased seed cavity, reduced endosperm volume, and integume...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

some cerasus sub-genus wild species that are used as rootstocks in sour and sweet cherry propagation can also be employed in breeding programs. the aim of this study was to clearly evaluate some characteristics of subgenus cerasus genotypes to be used in the future cherries' breeding programs. in order to evaluate some morphological characteristics of the vegetative parts as well as seeds ...

The Active Wavelet Network (AWN) [9] approach was recently proposed for automatic face alignment, showing advantages over Active Appearance Models (AAM), such as more robustness against partial occlusions and illumination changes. In this paper, we (1) extend the AWN method to a view-based approach, (2) verify the robustness of our algorithm with respect to unseen views in a large dataset and (...

Awns, important domestication and agronomic traits in rice (Oryza sativa L.), are conferred by polygenes and the environment. Near isogenic line (NIL) pairs BM33 and BM38 were constructed from crosses between awnless japonica cv Nipponbare as recurrent parent, and lines SLG or Funingxiaohongmang (awned japonica accessions), respectively, as donors. In order to study the genetic and molecular me...
