    Members of Alliaceae; better source of plant lectins to combat resistance against sucking pests of crops
    (INT SOC HORTICULTURAL SCIENCE, 2016) Bakhsh, A.; Zia, M. A. B.; Hussain, T.; Tekeli, F. O.; Gokce, A. F.; Gokce, AF
    Transgenic Bt crops were planted on an area of approximately 45 million hectares in combination with herbicide resistance trait in recent years. The available scientific literature does not show any concrete evidence of cry gene exhibiting resistance against sucking pest particularly in commercialized crops. Therefore, the common crop protection practice against sucking pests is the application of chemical insecticides both for transgenic and non transgenic crops. The increased pest status and resistance to chemical insecticides provide impetus for the development of alternative management strategies. Lectins are carbohydrate-binding proteins that specifically recognize glycans of glycoproteins, glycolipids or polysaccharides with high affinity and mediate various cell-cell and host-pathogen interactions, besides innate immune responses. The ability of plant lectins to control sap-sucking insects is considered as most significant as these devastating pests are unresponsive to insecticidal Bt genes and are constant threat to crops by damaging them directly or by acting as vector for different pathogens. Different researchers worldwide have established the successful efficacy of plant lectins against sucking insect pest in transgenic rice, tobacco, oilseed rape, potato, wheat, maize, chickpea and cotton. Among various plant lectins introduced in crops, the monocot mannose binding lectins i.e. garlic (Album sativum L. leaf agglutinin, ASAL), onion (Album cepa L. agglutinin, ACA), snowdrop (Galanthus nivalis L. agglutinin, GNA) has exhibited quite promising and significant resistance to jassids (Amrasca devastans), whiteflies (Bernisia tabaci) and aphids (Aphis gossypii). The present study focuses the research endeavours in various transgenic crops expressing plant lectins gene(s) against sucking pests of crop plants.

    MUTATION BREEDING IN POTATO; ENDEAVORS AND CHALLENGES
    (Pakistan Agricultural Scientists Forum, 2018) Zia, M. A. B.; Bakhsh, A.; Caliskan, M. E.
    Mutation breeding is a resolute application of mutations to develop the desired characteristics in crops to get increased yield. Since the first release of mutant potato cultivar in Belgium in 1968, mutation breeding in potato found a niche in plant breeding because of the increased quality and yield improvements. Six mutated potato cultivars have been registered from all over the world. Many scientists are working on potato mutation breeding and have reported appreciable results especially quality improvement of the crop, decreased amylose contents, salt and heat tolerance, and resistance to late blight. However conventionally induced mutation has some distinct limitations, especially in the applications of crop-breeding, as percentage of desired mutation is very less in the field; by using in vitro techniques with the combination of routine mutagenesis has overawed this obstruction too. Thus this technique can be the part of the other plant breeding techniques to increase the yield and to nourish the rapidly increasing world's population. The present review focuses the achievements, endeavors and future challenges of mutation breeding in potato.
