“…Leaf rolling is a transient morphological expression of reduced turgor (e.g. O'Toole and Cruz 1980; Kadioglu et al 2012). Epicuticular waxes on the leaf surface minimise non-stomatal transpiration and enhance photoprotection (Shepherd and Wynne Griffiths 2006;Samuels et al 2008).…”

Drought is a predominant cause of low yields worldwide. There is an urgent need for more water efficient cropping systems facing large water consumption of irrigated agriculture and high unproductive losses via runoff and evaporation. Identification of yield-limiting constraints in the plant-soil-atmosphere continuum are the key to improved management of plant water stress. Crop ecology provides a systematic approach for this purpose integrating soil hydrology and plant physiology into the context of crop production. We review main climate, soil and plant properties and processes that determine yield in different water-limited environments. From this analysis, management measures for cropping systems under specific drought conditions are derived. Major findings from literature analysis are as follows. (1) Unproductive water losses such as evaporation and runoff increase from continental in-season rainfall climates to storage-dependent winter rainfall climates. Highest losses occur under tropical residual moisture regimes with short intense rainy season. (2) Sites with a climatic dry season require adaptation via phenology and water saving to ensure stable yields. Intermittent droughts can be buffered via the root system, which is still largely underutilised for better stress resistance. (3) At short-term better management options such as mulching and date of seeding allow to adjust cropping systems to site constraints. Adapted cultivars can improve the synchronisation between crop water demand and soil supply. At long term, soil hydraulic and plant physiological constraints can be overcome by changing tillage systems and breeding new varieties with higher stress resistance. (4) Interactions between plant and soil, particularly in the rhizosphere, are a way towards better crop water supply. Targeted management of such plant-soil interactions is still at infancy.We conclude that understanding site-specific stress hydrology is imperative to select the most efficient measures to mitigate stress. Major progress in future can be expected from crop ecology focussing on the management of complex plant (root)-soil interactions.

The holostemparasitic plant Cuscuta parasitizes various plants and sucks nutrients from the host stem. We used Cuscuta japonica as the parasite and Momordica charantia as the host plant, and described their interaction. The parasitized Momordica stems started swelling as a hypertrophic response within 3 days after parasitization. Concurrently, the Cuscuta stem grew rapidly and developed bigger scale leaves than usual. Parasitized Momordica stems reduced photosynthetic activity. Histological observation revealed no programmed cell death but an increased number of vascular bundles in the Momordica stem, especially near the Cuscuta hyphae. The defensive response of Momordica mainly involved the SA pathway. Drastic increase of tZ-and DZ-type cytokinins in Momordica stems would play an important role for hypertrophy. Cuscuta had higher cZ endogenously and our results imply that each subtype of CK might play different roles during parasitization process. Comprehensive plant hormone analysis provides new insights into plant interaction studies.

“…According to Chutia and Borah (2012), traditional rice varieties (such as Dular, Siam and Puteh Perak) had long and droopy leaves with larger leaf angle, are more susceptible to rolling due to their ability to conserved water in plant tissue. Reduction of transpiration rate by creating microclimate is one of the benefits of leaf rolling (KADIOGLU; TERZI, 2007;KADIOGLU et al, 2012). It has been reported that greater leaf rolling may be an important indicator linked to drought tolerance and may have a positive impact on crop yield under water stress conditions.…”

Drought stress has now become a severe threat to ensure food security in the developing world as well as in Malaysia. To dertermine physiological and molecular determinants of drought stress and screening of drought tolerant rice varieties, an experiment was conducted in a greenhouse at Universiti Putra Malaysia using eleven rice varieties and two irrigation regimes (well irrigated and water stressed). The present study indicated that traditional rice variety Puteh Perak and Siam is superior drought tolerant while IRRI 2011-IRLON Plot no: 064, MR 220 and BRRI Dhan 56 are moderately drought tolerant, and IRRI 2011-IRLON Plot no: 050 and MR 84 are drought sensitive rice variety. Drought tolerance of those varieties were measured based on rate of tiller reduction, leaf rolling score and drought score during water stress condition. Leaf rolling score was positively correlated to drought score, chlorophyll content and proline accumulation. Significant increase in the proline accumulation and antioxidant enzyme activities (peroxidase and catalase) were also observed under drought stress in all the rice varieties except Siam and Puteh Perak. All the rice varieties including drought tolerant and sensitive showed the existence of OsLEA 30 genes.
