Low rainfall remains a big
concern for
the agricultural industry
The South African Weather Service may have offered an optimistic outlook pointing towards the possibility of
above-normal rainfall between December and February 2019, but there has, so far, been little evidence of an
improvement in rainfall. Additionally, fears of an extreme dryness, typically called “El Niño”, later in the 2019

Space missions are a bit like a marathon with checkpoints – only once the first model of a satellite has been successfully
tested will construction commence on the actual flight model. The Eu:CROPIS satellite developed by the German
Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), which will operate two greenhouses under
Martian and lunar conditions, has now reached this milestone – construction of the flight model can now begin. The
finish line is already in sight: launched by Space-X, the satellite and its scientific payload took off for outer space on
board the Falcon 9 in the second half of 2017. “We constructed the model here at DLR Bremen, and conducted
rigorous flight tests,” explained engineer Hartmut Müller, Project Manager for satellite construction at the DLR Institute
of Space Systems.

The females lay eggs singly, usually on younger leaves or
flower buds. The young larvae start by eating these, then often
move on to the fruit and stems. They burrow into the fruit and

6 TAMATIENUUS • DESEMBER 2018Sticky, prickly and
heavily armed
Armed with long thorns and sticky stems, newly described plant
Solanum kollastrum might look like a villain by plant standards,
but a closer look on this curious new species will reveal its
star-like nature in the context of its ecosystem.
Recently described in open access journal PhytoKeys, this newly
discovered tomato relative boasts stems densely armed with prickles
of up to 17 mm long and to 2.3 mm wide at the base. In fact, the new
species is baptised after yet another showy defence mechanism. The
name kollastrum comes from the Greek words for glue and star, referring
to the peculiar sticky hairs that end in a star-like formation. While all this
heavy armour might at first fool you that this new species lives in isolation, a
closer look has revealed that, contrary to the expectations, S. kollastrum starts
as the good guy in its ecosystem. In its own right, Solanum is an extremely
diverse plant genus to which important crops such as potatoes, tomatoes and
eggplants belong. Endemic to eastern Brazil, the known records of the armed
new species are mostly concentrated along the Mucuri River watershed, where it
inhabits edge of small forest fragments. In fact, the species is especially seen in areas
at the base or on the peculiar and gigantic geological formations known as inselbergs or
‘sugar loaves’.Some populations were also found in disturbed sites near these rock outcrops,
such as borders of unpaved roads and pastures. “The discovery of S. kollastrum, a robust and
conspicuous plant growing at the roadsides in regions close to large urban centres, highlights how
insufficiently known the Brazilian flora is,” explain authors from the Universidade Federal de Minas
Gerais and Universidade Federal do Oeste do Pará, Brazil.“This highlights how urgent the need is to
describe, study and conserve the country’s plant diversity. Thus, we hope that this discovery encourages the
study on the most diverse aspects of this species’ biology.”

Genetics of Stress
While trying to understand genetics of stress to make tomatoes and other crops more productive,
Indian researchers have identified a gene that helps the tomato plant tackle pathogens as well as heat stress.
Source: Environmental and Experimental Botany.
Scientists at New Delhi-based National Institute of Plant Genome
Research (NIPGR) have deciphered critical role of a single gene -
SlDEAD35 - in tomato plant whose expression controls its response to
both heat stress and viral infection.
It has been known that RNA helicases, one of the largest gene
families that function in almost all aspects of RNA metabolism, play a
role in growth, development and stress response of a species. They
are present in most of the organisms ranging from bacteria to humans,
as well as plants.
However, its role in tomato plant’s response towards environmental
stresses was not known. The NIPGR team observed that two
genes (SlDEAD23 and SlDEAD35) help plants withstand biotic and
abiotic stresses. “We had looked into the transcriptome dynamics
of a tomato variety tolerant to Tomato leaf Curl New Delhi Virus
infection. Comparative transcriptome analysis of virus infected as
well as uninfected plants showed a significant upregulation of one DEAD-box RNA helicase gene which prompted us to go for its
characterisation,” says Dr Manoj Prasad, who led the research team. “We find that SlDEAD35 gene plays crucial role against virus as
well as heat stress, which might provide the framework for improved yield and tolerance against combined stress in tomato,” he adds.
Developing systems for tolerance or resistance against combined stresses is important for future crop production. “We have found
a candidate gene which might provide the framework to understand the science behind plants’ response against combined stresses.
We can introduce the gene through molecular breeding to develop varieties for the combined stress tolerance in tomato,” says the
lead author, Saurabh Pandey.
