“…Cold stress during germination, i.e. germination at temperature below 20°C (Yoshida 1981), and ageing stress during seed storage bring about retardation of germination potential (cold stress- Peterson et al 1978;Kabaki et al 1982 andageing stress-Osborne 1980). Table 2 shows % reduction of root length at germination of stressed seeds compared to that of unstressed seeds.…”

Germination potential, i.e. vigour manifested at sensu stricto germination, was studied in 22 rice varieties to distinguish between the genetic control for low vigour (lv) at fresh harvest and lv after ageing of seeds. For identifying seed vigour-associated DNA marker(s), correlative studies between (1) physiological parameters viz. germination of (a) unaged seeds under optimum and cold stressed condition, (b) aged seeds under optimal condition and (2) growth-associated biochemical parameters viz. alcohol dehydrogenase (ADH) and esterase (EST) activity during early germination of fresh seeds and antioxidant potential in dry embryos of fresh and aged (1 year) seeds were undertaken. ADH and EST activity as well as antioxidant potential showed positive correlation with speed of embryo emergence and early seedling growth of seeds. The reduction of antioxidant potential in aged seeds also appeared proportional to germination performance. Random amplified polymorphic DNA analysis between the varieties was correlated with the abovementioned vigour parameters, using multiple regression analysis. This led to the identification of four bands associated with the vigour trait at 99% significance level; of these, the * 900-bp DNA fragment (named as HVAC 19), through basic local alignment search tool nucleotides analysis, revealed a sequence homology with acetyl CoA carboxylase (ACCase) gene of wheat at 94% similarity level.

Male reproductive development in rice is very sensitive to various forms of environmental stresses including low temperature. A few days of cold treatment (<20°C) at the young microspore stage induce severe pollen sterility and thus large grain yield reductions. To investigate this phenomenon, anther proteins at the early stages of microspore development, with or without cold treatment at 12°C, were extracted, separated by two-dimensional gel electrophoresis, and compared. The cold-sensitive cultivar Doongara and the relatively cold-tolerant cultivar HSC55 were used. The abundance of 37 anther proteins was changed more than 2-fold after 1, 2, and 4 days of cold treatment in cv. Doongara. Among them, one protein was newly induced, 32 protein spots were up-regulated, and four protein spots were down-regulated. Of these 37 protein spots, we identified two anther-specific proteins (putative lipid transfer protein and Osg6B) and a calreticulin that were down-regulated and a cystine synthase, a ␤-6 subunit of the 20 S proteasome, an H protein of the glycine cleavage system, cytochrome c oxidase subunit VB, an osmotin protein homologue, a putative 6-phosphogluconolactonase, a putative adenylate kinase, a putative cysteine proteinase inhibitor, ribosomal protein S12E, a caffeoyl-CoA O-methyltransferase, and a monodehydroascorbate reductase that were up-regulated. Identification of these proteins is available upon request. Accumulation of these proteins did not vary greatly after cold treatment in panicles of cv. Doongara or in the anthers of the cv. Rice (Oryza sativa L.) evolved in tropical and subtropical areas, and as a result it has the characteristic of being vulnerable to cold weather. In particular, the combination of the low temperature sensitivity and a maximal sensitivity to these temperatures at precise stages of pollen microspore development (1) makes cool midseason temperatures the major environmental limitation (other than soil and water) for growing rice in temperate regions and at high elevations in the tropics (2). During the life cycle of rice, pollen microspore development at the booting stage is known to be the most susceptible to cool weather damage (3). Cold damage at this reproductive stage of rice causes limitation to the yields of temperate-grown rice around the world and can reduce yields to 40% (3, 4). The main cause of this damage is pollen sterility resulting from low temperature damage at the early stage of microspore development (1). The developmental stage most sensitive to the various forms of environmental stress, including cold damage, is just after meiosis. That is tetrad to early microspore phase, or the young microspore stage (5). In cold-treated rice plants, both cytological and histological abnormalities are greater in the anthers than in the pistil or other organs of the flower, and the cold damage can be rescued by artificial pollination with healthy pollen (5). In this process of cold damage, anthers become smaller, and cells in the tapetal layer in the anthers that surrounds a...

“…Under field conditions, rice seedlings are exceptionally subjected to freezing periods, more regularly they endure chilling, whereas the most common situation is ST (Greaves 1996, Morsy et al 2005, Zhang et al 2012. Although some early studies demonstrated that rice growth rate and metabolism are noticeably inhibited in the range of 15-20°C (Kabaki et al 1982, Takanashi et al 1987, the physiological bases for rice growth delay by ST remain fairly unexplored. In contrast, numerous authors have focused on morphological, biochemical and molecular responses to chilling and freezing in this crop (Peng and Ismail 2004, Bertin et al 1996, Bonnecarr ere et al 2011, Wang et al 2013.…”

The physiological response of multiple rice cultivars, eighteen initially and eight cultivars later on, to suboptimal temperatures (ST) conditions was investigated in laboratory and outdoor experimental conditions. Treatment with ST decreased growth in different extents according to the cultivar and affected the PSII performance, determined by chlorophyll fluorescence fast‐transient test, and stomatal conductance, regardless the experimental condition. Two groups of cultivars could be distinguished on the base of their growth and physiological parameters. The group of cultivars presenting higher growths displayed optimal JIP values, and higher instantaneous water use efficiency (WUEi), due to a lower Gs under ST, unlike cultivars showing lower growth values, which presented worse JIP values and could not adjust their Gs and hence their WUEi. In this work, we detected at least two cultivars with superior tolerance to ST than the cold tolerant referent Koshihikari. These cultivars could be used as parents or tolerance donors in breeding for new crop varieties. On other hand, positive and significant correlations between data obtained from laboratory and outdoor experiments suggest that laboratory measurements of most of the above mentioned parameters would be useful to predict the response of rice cultivars to ST outdoor.
