Botanical Briefs: the Fig—Ficus Carica L
Close Encounters With the Environment Botanical Briefs: The Fig—Ficus carica L. Thomas W. McGovern, MD Clinical Importance Figs can cause irritant reactions with erythema, ulceration, or bullae; phototoxic reactions with bullae and hyperpigmentation sometimes followed by depigmentation and keloids; and chronic eczema with paronychia.1 These dermatoses occur in those who cultivate, gather, pack, or consume figs. The ability of fig plant extracts to stimulate pigmentation in vitiligo patients has been known for almost 2000 years,1 and in India fig extracts are used to treat eczema and psoriasis.2 In addition, the latex has been used as a treatment for warts.3 Family The family Moraceae (the mulberry family) contains 53 genera with about 1400 species, approximately 800 of which are in the genus Ficus. Family members include trees, shrubs, lianes, and herbs that usually have lacticifers with a milky latex.3 Distribution of Plant Ficus carica is probably a native of southwest Asia that rapidly spread to the Mediterranean region, where it was cultivated in Egypt at least 6000 years ago. Today the fig is cultivated mainly in temperate climates throughout the world but also thrives in tropical and subtropical regions. Ficus carica can grow among rocks, in woods, and in hot, dry soils. The first figs in the New World were planted in Figure 1. A young tree of Ficus carica L. about 3-feet Mexico in 1560. In 1669, Europeans sent figs to tall.

Altogether, 8 species under 3 subfamilies are already reported from Sunderban Biosphere Reserve. Present communication reports Batocera rufomaculata (De Geer, 1775) for the first time from this Biosphere reserve. Keywords: Sunderban Biosphere Reserve, Cerambycidae, Lamiinae, Batocera Introduction Sunderban region in India is 9600 sq km (4200 sq km of Reserved Forest and 5400 sq km of non-forest, inhabited region) which constitutes the Sunderban Biosphere Reserve (SBR). Indian Sunderban is bound on the west by river Muriganga and on the east by rivers Harinbhahga and Raimangal. Administrative boundary of the Sunderban is spread over two districts i.e. North 24-Parganas (Hingalganj, Hasnabad, Haroa, Sandeskhali - I,II, and Minakhan blocks) and South 24-Parganas (Sagar, Namkhana, Kakdwip, Patharpratima, Kultali, Mathurapur-I,II, Jaynagar-I,II, Canning-I,II, Basanti and Gosaba blocks).The extent of mangrove Reserve Forests in Indian Sunderban is around 4260 sq km, out of which 55% is under land vegetation cover and balance 45% is under water body/ inter-tidal zone. Studies on beetles and weevils (Coleoptera) in Sunderban region is very poor. -
Investigations Into Stability in the Fig/Fig-Wasp Mutualism
Investigations into stability in the fig/fig-wasp mutualism Sarah Al-Beidh A thesis submitted for the degree of Doctor of Philosophy of Imperial College London. Declaration I hereby declare that this submission is my own work, or if not, it is clearly stated and fully acknowledged in the text. Sarah Al-Beidh 2 Abstract Fig trees (Ficus, Moraceae) and their pollinating wasps (Chalcidoidea, Agaonidae) are involved in an obligate mutualism where each partner relies on the other in order to reproduce: the pollinating fig wasps are a fig tree’s only pollen disperser whilst the fig trees provide the wasps with places in which to lay their eggs. Mutualistic interactions are, however, ultimately genetically selfish and as such, are often rife with conflict. Fig trees are either monoecious, where wasps and seeds develop together within fig fruit (syconia), or dioecious, where wasps and seeds develop separately. In interactions between monoecious fig trees and their pollinating wasps, there are conflicts of interest over the relative allocation of fig flowers to wasp and seed development. Although fig trees reap the rewards associated with wasp and seed production (through pollen and seed dispersal respectively), pollinators only benefit directly from flowers that nurture the development of wasp larvae, and increase their fitness by attempting to oviposit in as many ovules as possible. If successful, this oviposition strategy would eventually destroy the mutualism; however, the interaction has lasted for over 60 million years suggesting that mechanisms must be in place to limit wasp oviposition. This thesis addresses a number of factors to elucidate how stability may be achieved in monoecious fig systems. -

Red palm weevil, Rhynchophorus ferrugineus Olivier, is one of the most destructive pests harming palm trees. However, genomic resources for R. ferrugineus are still lacking, limiting the ability to discover molecular and genetic means of pest control. Methods. In this study, PacBio Iso-Seq and Illumina RNA-seq were used to generate transcriptome from three developmental stages of R. ferrugineus (pupa, 7th-instar larva, adult) to increase the understanding of the life cycle and molecular characteristics of the pest. Results. Sequencing generated 625,983,256 clean reads, from which 63,801 full-length transcripts were assembled with N50 of 3,547 bp. Expression analyses revealed 8,583 differentially expressed genes (DEGs). Moreover, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that these Submitted 5 March 2020 Accepted 29 September 2020 DEGs were mainly related to the peroxisome pathway which associated with metabolic Published 2 November 2020 pathways, material transportation and organ tissue formation. -

Figs in Merced County Compared to the 92,000 Acres of Almonds in Merced County, the Modest 2,000 Acres of Figs Seems Insignificant
Merced County Figs In Merced County Compared to the 92,000 acres of almonds in Merced County, the modest 2,000 acres of figs seems insignificant. But that acreage makes Merced County the second most important fig county in North America – second only to Madera. The mild Mediterranean climate of the San Joaquin Valley and the availability of water during summer make this the perfect area to grow figs. Figs have a history in Merced County reaching back probably 100 years. At one time, one of the unofficial slogans for Merced County was “Home of the Fig”. Most common fig variety in the County is the Calimyrna, which is used for drying and for paste. The best fruits are sold whole and the rest are processed into paste for a variety of products – the most famous of which is the fig “New- ton”. The (black) Mission fig is harvested mostly for dried and paste, but some fruit is hand picked from the tree and marketed fresh – some to far away places. The light green Kadota fruit is dried, shipped fresh and sometimes canned. The only fig cannery in the country is here in Planada – Oasis Foods. Figs are interesting botanically. With very soft wood, morphologically, figs are somewhat similar to grapes. They can be damaged by very cold winter temperatures. The Ka- dota trees are trained very close to the ground and some- times can be confused as very large head-trained grape- vines. The Kadota orchards around Planada are a favorite subject for photographers, especially when the mustard is in bloom. -

Weiblen University of Minnesota, Department of Plant Biology, St. Paul, Minnesota 55108; e-mail: [email protected] Key Words Agaonidae, coevolution, cospeciation, parasitism, pollination ■ Abstract In the two decades since Janzen described how to be a fig, more than 200 papers have appeared on fig wasps (Agaonidae) and their host plants (Ficus spp., Moraceae). Fig pollination is now widely regarded as a model system for the study of coevolved mutualism, and earlier reviews have focused on the evolution of resource conflicts between pollinating fig wasps, their hosts, and their parasites. Fig wasps have also been a focus of research on sex ratio evolution, the evolution of virulence, coevolu- tion, population genetics, host-parasitoid interactions, community ecology, historical biogeography, and conservation biology. This new synthesis of fig wasp research at- tempts to integrate recent contributions with the older literature and to promote research on diverse topics ranging from behavioral ecology to molecular evolution.

NATIVE POLLINATORS Who Are They and Are They Important?
NATIVE POLLINATORS Who are they and are they important? Compiled by Jim Revell, Bedford Extension Master Gardener Reproduction – the goal One goal of all living organisms, including plants, is to create offspring for the next generation. One method for plants to accomplish this is by producing seed. Pollen – a fine-to-coarse yellow dust or powder – “bears a plant’s male sex cells and is a vital link in the reproductive cycle.” USDA Forest Service • Pollination is usually an unplanned event due to an animal’s activity on a flower Pollination • It is calculated that one out of every three or four mouthfuls of food or drink “The act of transferring consumed is provided by pollinators pollen grains from the • male anther of a flower to More than 150 food crops in the U.S. depend on pollinators; this includes almost all fruit the female stigma.” and grain crops (see Handout, “List of USDA Forest Service Pollinated Foods” by Pollinator Partnership) • 80% or more of all plants worldwide Pollinator Methods: (including food crops) are pollinated by animals (biotic pollination) ABIOTIC: Without • Of the ≤20% abiotic method involvement of • organisms 98% are pollinated by wind • 2% are pollinated by water BIOTIC: Mediated by • ±200,000 species of animals around the animals world act as pollinators • Of the ±200,000 about 1,000 species are vertebrates (birds, bats, small mammals) Abiotic Pollinators: Wind | Water Left: Diagram of how Wind Pollination works; picture of windblown pollen from male cone of a Lodgepole Pine.
