TL;DR: Results show that studied Lathyrus species are rich in phenolic compounds with higher antioxidant activity than phenolics of widely consumed legumes such as soy, chickpea or lupin.
Abstract: Antioxidant activity of seed phenolics was studied in the following Lathyrus species: Lathyrus hirsutus , Lathyrus filiformis , Lathyrus sativus , Lathyrus cicera , Lathyrus angulatus , Lathyrus sphaericus , Lathyrus annuus , Lathyrus clymenum , Lathyrus pratensis , Lathyrus ochrus , Lathyrus aphaca , Lathyrus latifolius , Lathyrus setifolius , Lathyrus tingitanus and Lathyrus amphicarpos . Phenolic contents ranged from 3.8 mg/g meal in L. setifolius to 29.2 mg/g meal in L. sphaericus . In general, non-cultivated Lathyrus species contained higher phenolic contents than cultivated ones. A negative correlation between seed size and phenolic contents was observed and was related to the higher proportion of hulls in the smaller seeds. L. annuus possessed phenolics with highest specific antioxidant activity. These phenolics were more than two times more antioxidant than equivalent amounts of phenolics extracted from commercial chickpea, lupin or soy. On the other hand, L. aphaca possessed the highest antioxidant activity per mg of flour extract. This antioxidant activity was twice that observed in same amounts of extracted flours from commercial chickpea, lupin or soy. Results show that studied Lathyrus species are rich in phenolic compounds with higher antioxidant activity than phenolics of widely consumed legumes such as soy, chickpea or lupin. In conclusion, Lathyrus may represent an interesting source of phenolic compounds with high antioxidant activity that may be useful as natural antioxidants and contribute to revalorize the cultivation of these legumes.

TL;DR: It was concluded that stipules are the principal photosynthetic organs in L. aphaca.
Abstract: Occurrence of stipules of different shapes, sizes and varying configurations, has been reported in species of many angiosperm families. However, the functions of stipules in the biology of plants that carry them remain to be understood. There is perception that stipules that have the green coloration of chlorophyll are photosynthetically active. Here, total photosynthesis in the stipules and leaves of Lathyrus aphaca was investigated, together with the nature of heteroblasty and relative morphology and anatomy of stipules and leaves in this species. At each of the hundreds of nodes in the extensively branched post-flowering stage plants of L. aphaca, more than 95 % of photosynthesis occurred in the foliaceous stipules. The leaves in the form of simple tendrils at the nodes accounted for <5 % of photosynthesis. The stipules of L. aphaca were about as effective in photosynthesis as the foliaceous stipules of af and AF pea (Pisum sativum) plants. The L. aphaca stipules possessed all the cells/tissues that characterized photosynthetic leaves, stomata in epidermis, palisade and spongy mesophyll parenchyma, and vascular bundles. The tendrilled leaves were devoid of palisade tissue. The embryonic nodes bore stipule pairs of small size and compound leaves comprising of a pair of leaflets. Several nodes, above the embryonic nodes, bore fully developed stipule pairs but vestigial leaves (tendrils). It was concluded that stipules are the principal photosynthetic organs in L. aphaca.

TL;DR: The close homology of these proteins with the α subunits of the lectins from L. sativus and L. odoratus and various other members of the tribe Vicieae is discussed in relation to the phylogeny of the Leguminosae.

TL;DR: In L. tingitanus, constitutive heterochromatin showed two types of Q-band: one negative with quenched fluorescence at the centromeric regions of all the chromosomes and the other, positive with enhanced fluorescent at one or both sides of the negative bands.
Abstract: SUMMARYConstitutive heterochromatin was observed in Lathyrus aphaca, L. cicera, L. odoratus, L. sativus and L. tingitanus. C-bands in L. odoratus and L. tingitanus are centromeric or proximal in location. In L. tingitanus, only the short arm of Chromosome 3 showed a large telomeric band; this was detected by C-banding following Q-banding but not in directly C-banded preparations. In L. odoratus, while most C-bands showed as positive Q-bands with enhanced fluorescence, small telomeric bands showed no differentiation with quinacrine. In L. tingitanus, constitutive heterochromatin showed two types of Q-band: one negative with quenched fluorescence at the centromeric regions of all the chromosomes and the other, positive with enhanced fluorescence at one or both sides of the negative bands. No other species of Lathyrus investigated showed discrete negative Q-bands. In L. aphaca and L. cicera. Q-banding patterns are characterized by large telomeric positively fluorescent bands on most members of each complemen...
