Article
Full-text available
Lentil is an important pulse crop not only because of its high nutrient value but also because of its ecological advantage in a sustainable agricultural system. Our previous work showed that the cultivated lentil and wild lentil germplasm respond differently to light environments, especially to low R/FR-induced shade conditions. Little is known abo...
Article
Background and aims: Flowering time is important due to its roles in adaptation to different environments and subsequent formation of crop yield. Changes in light quality affect a range of developmental processes including flowering time, however little is known about light quality induced flowering time control in lentil. This study aims to inves...

Understanding environmental responses of pulse crop species and their wild relatives will play an important role in developing genetic strategies for crop improvement in response to changes in climate. This study examined how cultivated lentil and wild Lens germplasm responded to different light environments, specifically differences in red/far-red...

Lentil (Lens culinaris ssp. culinaris) is a nutritious and affordable pulse with an ancient crop domestication history. The genus Lens consists of seven taxa, however, there are many discrepancies in the taxon and gene pool classification of lentil and its wild relatives. Due to the narrow genetic basis of cultivated lentil, there is a need towards...

Widening the genetic base of minor grain legume crops such as lentil (Lens culinaris Medik.) is important for achieving future gains in productivity. In order to access genes from wild lentil species embryo rescue techniques are required to overcome reproductive barriers. Removing the seed coat from developing 14-day old immature hybrid seeds and c...
Chapter
Embryo abortion occurs frequently in wide crosses, and thus embryo rescue is required for survival of the next generation. Rescues are performed by either directly transferring the excised embryo to an artificial medium or indirectly through flower (ovary), immature seed (fertilized ovule), or pod (silique) culture. Various techniques used for oil...
Article
Cicer anatolicum, a perennial species, has ascochyta blight resistance superior to that found in the cultivated chickpea. However, hybridization barriers during early stages of embryo development curtail access to this trait. Since hormones play an essential role in early embryo development, we have determined the hormone profiles of 4-, 8-, and 12...
Article
Key message: Developmental context and species-specific hormone requirements are of key importance in the advancement of in vitro protocols and manipulation of seed development. Improvement of in vitro tissue and cell culture protocols in grain legumes such as embryo rescue, interspecific hybridization, and androgenesis requires an understanding o...
Article
Full-text available
Legumes are recalcitrant to androgenesis and induction protocols were only recently developed for pea (Pisum sativum L.) and chickpea (Cicer arietinum L.), albeit with low regeneration frequencies. Androgenesis is thought to be mediated through abscisic acid (ABA) but other phytohormones, such as auxins, cytokinins, and gibberellins, have also been...
Article
Faba bean (Vicia faba L.) was used as the rootstock for lentil scions to test the feasibility of using in vivo inter-generic grafting techniques as a substitute for root induction and as a tool in lentil genetic improvement. An accession of each of the six wild Lens species was used as the scion in grafts to faba bean breeding line FB50-9 rootstock...
Article
Wild European plum (Prunus ×domestica L.) is a rare and endangered species in China. To conserve this germplasm, a protocol for in vitro propagation of this species was developed. Nodal segments were used as the explants in our study. For the initiation of culture, B5 medium was better than Murashige and Skoog (MS) medium, which showed rapid growth...
Article
Strawberry (Fragaria ×ananassa Duch.) is one of the highly valuable and important fruit in the world. Strawberry fruits are highly perishable and vulnerable to tissue damage during postharvest storage. Besides, strawberry fruits can be easily infected with Botrytis cinerea during storage. Loss of strawberry fruit quality is mainly due to the onset...
Article
Phospholipase D, the key enzyme involved in membrane phospholipid catabolism, was localized in strawberry (Fragaria ananassa Duch.) fruits during development using immunohistochemical techniques. Typical structural features such as the nucleus, cell wall, plasma membrane, mitochondria and vacuole were noticeable in cells of young strawberry fruits....
Article
Turnover of membrane phospholipids is an integral feature of membrane biogenesis. During growth, membrane biogenesis keeps pace with the expanding and dividing cells, whereas during senescence, membrane phospholipids are catabolized leading to membrane deterioration. The growth of strawberry fruits is totally dependent on achene-derived auxins. The...
Article
Phospholipase D alpha (PLD, EC 3.1.4.4)) is a key enzyme involved in membrane deterioration that occurs during fruit ripening and senescence. The biochemical and molecular characteristics of PLD was studied in strawberry (Fragaria ananassa Duch) fruits, which are non-climacteric fruits. PLD activity was primarily associated with the mitochondrial a...
Article
Expressions of Ginlfy and GinNdly gene were studied by northern blotting in different organs and stages of Ginkgo Biloba. Ginlfy gene was expressed in different organs such as root, stem, leaf of juvenile tree, male tree and female tree, and in different stages of male flower bud and female flower bud. It was inferred that Ginlfy gene could be expr...
