Although orphan crops are also known by different names (e.g. underutilized-, lost- or disadvantaged-crops), they all refer to a group of crops that are vital to the economy of developing countries due to their suitability to the agro-ecology and socio-economic conditions, but remain largely unimproved due to less at- tention has been given by the world scientific community. In order to boost food production in Africa emphasis should be given, not only to the major crops but also, to the orphan crops. The topics covered in this issue range from germplam collection and conservation to the application of modern techniques (Bhattacharjee; Dominique & Daniel). Under ‘Comparative Ge- nomics’ Patterson and colleagues showed the relationships of different orphan crops at a molecu- lar level. The same group led the international group of scientists to complete the sequence of sor- ghum genome (Nature 457:551-556; 2009). Sorghum is also another important crop of Africa that was until recently considered as an orphan crop. But due to concerted efforts made by the national and international institutes, significant number of cultivars with desirable agronomic traits reached the farming community. Gedil presents how bioinformatic tools can be applied to the orphan crops. Recently, some orphan crops researchers got an opportunity to implement modern improvement techniques that have proved to be efficient in the improvement of major crops of the world. Among these, tissue culture (Dubois) and TILLING (Esfeld & Tadele) are discussed in detail. In addition, genome sequencing has been recently completed for orphan crops such as cassava and in pro- gress for tef (Plaza et al.). Lambein and colleagues report their efforts to remove toxic substances from the two orphan crops that are extremely tolerant to drought but cause neuro-degenerations when consumed without proper processing. ‘Who is who in African orphan crops’ presents the names and addresses of institutes di- rectly or indirectly involved in orphan crops research and development (Tadele). Some key organiza- tions might be missed from the list but the list provides useful information, at least, for orphan crops researchers who need to establish research partnerships and are seeking for grants. On behalf of orphan crops researchers, I take this opportunity to thank the editors of ATDF Journal for giving the chance to the African Orphan Crops. In addition, I would like to thank all or- ganizations who provide financial and technical supports for orphan crops research and develop- ment. Finally, my personal thanks to all contributors who managed to write the articles despite their other commitments.

Due to the time and energy required to extract resources from 15 morphologically complex flowers, these plant species potentially compete for pollinators with co- 16 flowering plants that have more easily accessible resources. A widespread floral mechanism 17 restricting access to pollen is the presence of tubular anthers that open through small pores or slits 18 (poricidal anthers). Some bees have evolved the capacity to remove pollen from poricidal anthers 19 using vibrations, giving rise to the phenomenon of buzz-pollination. These bee vibrations that are 20 produced for pollen extraction are presumably energetically costly, and to date, few studies have 21 investigated whether buzz-pollinated flowers may be at a disadvantage when competing for 22 pollinators’ attention with plant species that present unrestricted pollen resources.

    YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work.

  • Characterization of a Type 3 Metallothionein Isolated from Porteresia Coarctata
    BIOLOGIA PLANTARUM 55 (1): 119-124, 2011 Characterization of a type 3 metallothionein isolated from Porteresia coarctata B. USHA, N.S. KEERAN, M. HARIKRISHNAN, K. KAVITHA and A. PARIDA* Plant Molecular Biology Laboratory, M.S. Swaminathan Research Foundation, Taramani, Chennai-600113, India Abstract Metallothioneins are involved in detoxification of heavy metals. A cDNA encoding type 3 metallothionein (PcMT3) was isolated from the salt stressed leaf cDNA library of Porteresia coarctata (Roxb.) Tateoka (wild rice) that grows well in the heavy metal laden estuarine soils. The PcMT3 cDNA (581 bp) encodes a protein of 64 amino acids. PcMT3 is highly homologous (82 %) to OsMT-I-3a of rice, but is unique from other type 3 plant MTs due to the presence of an additional glycine residue in the C-terminal domain. Analysis of the 5′ upstream region of PcMT3 showed the presence of cis-acting elements like the CG box and STRE previously reported to be involved in gene expression under heavy metal stress. Southern analysis suggested the presence of more than one copy of PcMT3-like sequences in the P. coarctata genome. Analysis of genomic clone of PcMT3 revealed the presence of two introns. A comparison of the genomic sequence of PcMT3 with closely similar type 3 MTs from rice and mangrove species revealed conservation in the number and position of introns. Transcript profiling for PcMT3 in P. coarctata leaves in the presence of Cd, Cu and Zn showed an increase in transcript accumulation. Additional key words: cis-acting elements, heavy metals, salt stress, wild rice. Introduction Plants acquire heavy metal tolerance through various reported in plants like rice, hybrid poplar, oil palm and mechanisms like compartmentalization, sequestration, lichens (Abdullah et al.

Ex. A. Rich.) Harm. Adesoye, A. I. and Nnadi, N. C. Department of Botany and Microbiology, University of Ibadan, Ibadan, Nigeria. Accepted 21 October, 2011 In this study the chromosome number, chromosome length and mitotic indices of 21 accessions of African Yam Bean (AYB) were determined. To accomplish this, the best time to harvest growing root tips was identified by measuring mitotic index of chromosomes prepared from root tips of accession TSs148 collected at two hours interval within a 24 h study period from 8 am to 6 am of following day. Cell division occurred throughout the day and at night with the rate of division increasing to a peak at midday. The highest percentage of metaphase cells (34.01%) was obtained from roots harvested at about 12:00 noon. In terms of the root tip to shoot tip that gave a higher mitotic index a ratio of 13:8 was observed among 21 accessions studied. A diploid chromosome count ranging between 2n = 20 to 24 was observed with the chromosome number 2n = 22 being the most frequent. The chromosomes of the accessions studied were generally small in size ranging between 0.58 to 1.84 µm. On the basis of chromosome size, the different accessions of AYB could be divided into three different groups.

It is abundant and diverse, with complex taxonomic relations. In order to expand the knowledge about the classification of Kazakhstan species and compare it with classical studies, matK genes of nine local species in- cluding endemic were sequenced. The infrageneric rank of one of them (A. kotuchovii) had re- mained unknown. In this study, we analysed results of sequences using two methods — NJ and MP and compared them with a median-joining haplotype network. As a result, monophyletic origin of the genus and subgenus Dracunculus was confirmed. Closeness of A. kotuchovii to other spe- cies of Dracunculus suggests its belonging to this subgenus. Generally, matK was shown as a useful barcode marker for the identification and investigation of Artemisia genus. Key words: Artemisia, Artemisia kotuchovii, DNA barcoding, haplotype network. INTRODUCTION (Bremer, 1994; Torrel et al., 1999). Due to the large amount of species in the genus, their classification is still complex Artemisia of the family Asteraceae is a genus with great and not fully completed.
